Bone & Ivory Guitar Bridge Pins with Size Chart
Guitar bridge pins of bone and fossil mammoth ivory (FMI). Beautifully hand crafted sets of guitar bridge pins made in our shop in Dover, Ohio. Bone and fossil mammoth pins can sell and ship internationally but no FMI sales to the US states of NY, NJ or CA.
These bone and ivory guitar bridge pins are available for Martin, Gibson and many other makes and models. We encourage you to look over our extensive PIN SIZE CHART BELOW (Scroll a lot to get it all) to select the pin size that is right for your make and model. Our pins have 3 mm dot inlays of abalone (US customers only), black dot (Industry standard and favorite), faux tortoise or plain head (No inlay).
Your pins are made in our Dover, Ohio shop by two fastidious American craftsmen who enjoy making great pins. Ivory and bone pins are nearly identical in sound transmission and either is a significant improvement over soft materials such as plastic or wood. Because the materials are acoustically nearly identical and that all our pins are machined to the same high standards we recommend the bone over the ivory as they are about one third the price. Fossil Mammoth Ivory has a beauty all its own and is ideal for the ultimate in guitar pin beauty for that very special guitar. FMI can vary from off white to dark tan and we strive to make most of these pins from the high grade almond colored material.

If possible, it is VERY good to measure any pin that fits your guitar with a dial caliper or a micrometer so as to obtain an accurate reading of the pins that fit your instrument. The measurement you are looking for is the diameter at the top of the tapered shaft. This measurement, along with the pin information below should pinpoint exactly what size you need to order. The chart above and information below, without the measurement, is very likely to work but the measurement is added security in knowing you have selected the right pin size for your instrument. Best to measure two or more pins you know fit your instrument.
In addition, we send an instruction sheet with each set of pins that covers the installation and proper fitting of your new pins.
Also, if you wish, you can mail us a pin and we can tell you if we can make it. If it is a non-standard size we can most likely make it but we cannot offer our money back guarantee. If we cannot make it you will need to pay return shipping of $ 6 for your pin. Select a pin or pins to send that fit in all of the holes of your instrument. See our contact page for mailing instructions and contact us by email prior to mailing.
Below the information on sizes will be additional information on specific guitars that you will want to read.
Pin SIZE 1 :
3 degree pin with .210" diameter at the top of the tapered shaft. Used for Martin guitars that were made before 1994, also Larrivee, Blanchard, Garrison, Goodall, Ryan, Lakewood,McPherson, Santa Cruz and Taylor guitars.These also work with Collings guitars made prior to 2002. These pins are slotted the full length of the tapered shaft and TO the skirt but NOT through the skirt (See photo above). If you need size 1 UNSLOTTED pins just purchase these and then email us through our contact page and let us know you need an UNslotted set and we will do that (price is the same for slotted or unslotted).
Pin Size 1T :
A size 1T is the same as a size 1 pin (3 degree and .210" diameter) but these are slotted THROUGH the skirt not just TO the skirt as it is on a size 1. We actually recommend the size 1T for any guitar needing the size 1. The slot extending through the skirt is helpful when setting the pins and goes unnoticed as a feature of the pin once installed.
Pin Size 1.3T :
This is a 3 degree pin with the slot through the skirt like the size 1T pin but with a slightly smaller shaft diameter. These are .203" diameter at the top of the tapered shaft rather than the .210" of the size 1.
PIN SIZE 2A :
5 degree pin with .220" diameter at the top of the tapered shaft. For modern Martin guitars (after 1994) and Gibson guitars. For Martin guitars see also our size 2C (listed below) for additional information to help you select the right pin and then scroll down further on this page to read the details under " Martin Guitars ".
These pins are slotted the full length of the tapered shaft and THROUGH the skirt. If you need UNSLOTTED pins just purchase the size pins you need and then email us through our contact page and let us know you need an UNslotted set and we will do that with no extra cost. Identify your order on the email by your name and city/state.
PIN SIZE 2A .223 :
5 degree pin with .223" diameter at the top of the tapered shaft. For Collings (after 2002) and Bourgeois/Pantheon guitars. These are 3 thousandths of an inch larger in diameter than the standard size 2A pins so they are also ideal for folks needing a larger 2A because their 2A pin fits sloppy. These come standard as un-slotted pins. If you need them slotted just place your order and then email us through our contact page and let us know you want them slotted. There is no extra charge. Identify your order on the email by your name and city/state.
PIN SIZE 2A .230 :
5 degree pin with .230" diameter at the top of the tapered shaft. These are for Martin Authentics. This is an un-slotted pin that fits all modern made Martin Authentic Line models.
PIN SIZE 2C :
5 degree pin with .215" diameter at the top of the tapered shaft. If you own a newer Martin guitar, chances are the bridge pins are installed so the head of the pin sticks up about 1/4" above the bridge. Our size 2A pins will fit the same way. Size 2C is the same degree of taper but with a reduced shaft diameter (.215 " diameter at the top of the tapered shaft just below the skirt) so they will sit further down in the bridge (usually flush with the bridge but this is a situation where measuring a pin will be most helpful).
IMPORTANT NOTES ABOUT SPECIFIC MAKES :
MARTIN GUITARS :
Martin guitars prior to 1994 are almost always size 1 which is a 3 degree pin with a measurement of .210" diameter at the top of the tapered shaft. If somebody modified the instrument it may have a different pin size but Martin was extremely consistent with this size prior to 1994. We recommend the 1T for these guitars which is the same as size 1 but with the slot extending through the skirt for ease of installation.
Martin went to a size 2A some time in 1994. The size 2A is .220" diameter at the top of the tapered shaft and is a 5 degree pin. Most Martin pin holes are drilled to .215" diameter at the factory so the size 2A, at .220", will stick up about 1/4" above the bridge. If your pins stick up about 1/4" above the bridge then the chances are high a size 2C will sit flush and you should buy size 2C. If your pins sit flush to the bridge the chances are high you should buy a set of 2A pins.
This is where measuring a pin that fits will come in handy and you can determine if you want a 2A (.220") or a 2C (.215"). It is our opinion that one should purchase the industry standard size 2A and if they stick up beyond your comfort level then you should have them fitted to the instrument by sizing the holes to accept the industry standard 2A. Any luthier worth his salt will have the 5 degree reamer and the skill to gently remove what will amount to dust from these holes for a perfect fitting of your new pins.
The recent Authentic models take UNSLOTTED pins. When the Authentics first came out they accepted 2A UNslotted pins.Then they went to the 2A.230 pin. This is .230" diameter at the top of the tapered shaft rather than the .220" diameter and it is also UNslotted.
Gibson Guitar specifies a size 2A for their instruments and we recommend this size. The chances are very high these will fit right. If you can measure the pins beforehand this will be helpful as some folks have found their Gibson pins to measure .210" at the top of the tapered shaft and have purchased size 1T which is a 3 degree pin.
The Gibson Epiphone usually takes the 1.3T (3 degree pin but smaller in shaft diameter than the 1T) but Epiphone pin sizes vary so it is best to measure the diameter at the top of the tapered shaft before buying.
Not Sure What You Have ???
For any instrument you may need help with on selecting the correct size please email us through our contact page with the following information and we will help you as best we can :
We cannot assure you we will have the pin you need but we assure you we will try to help:
1) Make, model and approximate year of manufacture of the guitar you need pins for.
2) Is the pin slotted and does the slot continue through the skirt or stop below it?
3) Measure the diameter of your pin at the top of the tapered shaft just under the collar. It is IMPORTANT that this measurement be done with a dial/digital caliper, or micrometer that will give you the dimension in decimal form to the thousandth of an inch (.210" for example). It is best to do this on a couple pins to get a common reading.
Lastly, PLEASE ensure your measurements are correct ! If in doubt, it's always best to purchase slightly over-sized pins and fit them to the guitar.
Last Resort !!!
As a last resort you can mail in a few pins that you know fit your guitar. See our contact page for our address to ship them to. We can analyze your pins and determine if we can make them. If they are a standard size we will call or email (put your contact info in with the pins you send) and let you know. If they are non-standard we may or may not be able to help you depending on the pins. If we cannot help you then you will need to pay $ 6 shipping if you want your pins returned. Chances are high we can make them. If standard size they are $ 39.95 per set (6 pins) and custom size pins are $ 60.00 per set for bone pins.
End Pin Size
Our standard end pin has a diameter of .315 " at the top of the tapered shaft. This fits most guitars including Martin. It has a 5 degree taper. It is very seldom this size does not fit but we also make custom size end pins when customers provide a size (diameter at top of tapered shaft). There is no extra charge for making a custom size end pin but we cannot accept returns on custom orders.
Strap Button Size
The strap button can be fitted to any instrument that uses this style of neck strap button. The final bit of class for those who want a totally tricked out guitar. Installation instructions are seen on the page selling the strap buttons - click on the "more information" button there.
