Thank you for your time.

Consider the difference: irreversible mods to original parts vs. saving the originals while using replacement parts. Thanks for your kind concern, though.

No, I don't plan to sell it, but I do wish to keep this ES-135 as stock. A replacement mounting plate is an excellent idea, however, so thanks for that. I'll look into it.

Thanks, but I wish to keep the guitar as stock. The plate's thickness is about 1/16", so cannot be re-tapped. There's also no guarantee to finding a screw of 1.5" length. The screws have tiny Phillips heads and they are white steel--soft and easily corroded. The Phillips points have degraded over the 32 years since the guitar left the plant.

No, it's Gibson who's under a rock. All Gibson had to do was use #3-48 tap to mount the P-100, but they went with some untraceable 1.5" fastener and f'd-up tooling that doesn't exist anymore. The neck on the ES-135 is absolutely perfect and the thinline profile is like stage armour. Perfect guitar except for the 1940s throwback pickup mounts.

Pitch describes the number of threads per unit length. Gibson's standard pickup height adjuster screw is #3-48, which means a screw of .099" diameter and 48 threads per inch of length. That standard Gibson fastener does not fit the P-100 mounting plate in my Gibson ES-135. I'm considering Gibson may have used a #3-56 screw.

The nearest Metric equivalent is 2.5 mm diameter, slightly smaller than #3-48, but the pitch is wrong.

Talked to Gibson some time back ... runaround. As for the diameter, there are only Metric and Imperial out there. The thread Gibson used is either an in-house limited batch or some arcane foreign type they bought up in quantity. I prefer to keep my 135 stock. Also, the screw has to fit through the P-100 pickup body, so, no drilling is possible.

Thanks, but length is not the problem. Diameter is the problem. Have tried the following: 2.0mm 2.5mm #2-56 #3-48 (Gibson's standard pickup height screw) Not one is a fit. Whatever screw Gibson used on the P-100, it's NOT a #3-48. It's slightly smaller but not as small as #2-56. This means the necessary screw is of diameter 0.0925". What the hell type is THAT? The four mount holes on the plate all take this unknown size.

Hi, The Phillips heads have worn out on my P-100 height adjusters. I am told they're #3-48 at 1.5". Impossible to find. So, I got new #3-48 size screws at 1.25". Standard Gibson pickup height screws. These are long enough to serve the neck pickup. NOPE. They bind in the mount plate. I tried a gold Gibson #3-48 x 1.25" I have on hand. NOPE. Binds in the mount plate. In desperation, I got M2.5 x 40 mm. NOPE. Binds in the mount plate. What thread did Gibson use for this ES-135?

Hello! Does anyone know a supplier for P-100 mounting screws? These are #3-48, the same thread as standard Gibson humbucker height adjustment screws, but they're 1.5" long. The original screws are Phillips type with small dome head. They corrode and bend after years of use. I've found #3-48 in 1-1/2" length as socket cap screws, but need the tiny Phillips dome head type. Thanks! John
