These are the very small screws which you'll see mounting truss rod covers in place on the headstock

6-32 UNC bolts usually turn up on American/Mexican/UK made instruments and parts - primarily pickups and switches, but they are becoming more common on Eastern made things too nowadays - its a little bit confusing, because theres a few different "types" (and you do get guitars that have a mix of different heads/lengths) - so as a quick, rough and ready guide.

Mount screw used to fix the base plate to a P90 bobbin, the base plate to single coils and Telecaster pickups, and various other jobs on the guitar.

#3 Round head Screw

Good quality Springs to hold Pickups against pick guards or mounting rings reliably, with a little bit of play.

Quite a specific screw to be honest - i cant think I've seen them being
used for anything else apart from mounting Filtertron pickups.

Silicone tuning used on single coils, traditionally used in place of the springs (which have become much more common nowadays) - but the old silicone tubing has a bit of vintage charm about it.

These are our basic “accessory mounting screws” that we  use on everything from scratch plates right through to jack sockets. For  simplicities sake, we just call them pickguard screws, but they really do a  multitude of jobs on a guitar.

A standard Arch Top pickguard bracket, designed to sit under a Les Paul® or 335® style pickguard, supporting the scratch plate in line with the stroke of the pick to protect the guitars finish.

Please note – these are not official Gibson® parts.

This is a slight adaptation on the standard arch top pickguard bracket. Basically, it’s an elongated version that sometimes appears on larger bodied guitars such as import hollow bodies.

We’ve called these screws “All Purpose” for so long now,
that I’ve actually struggled to get my head around the idea of calling them by
their “real” name - #3 x ¾”, Oval head screws!

A mandolin style pickguard bracket that’s occasionally seen on hollow bodied arch tops such as the ES series by Gibson, such as the 335, 339 and 330.

Available in the following colours.

"In House", we call these screws PSH's, but to give them their real name, they're #3 Countersunk screws! They're, in very simple terms, the "truly countersunk" version of our All Purpose screws, giving a slightly cleaner finish, (assuming) your recess is for a #3 screw head.

A twist on a common these with these "small guitar screws" - #2 countersunk screws!

If I was to be VERY strict about this, I've only ever seen these turn up on guitars in places i would expect to see #3 screws - almost entirely cross compatible (thread diameter is 2.2mm rather then 2.4mm) but, importantly, the heads are slightly smaller on the #2s vs. the #3s. (2.4mm vs 2.8mm)

Set of 8 3/4 Thread, Phillips, Pan head Screws designed to screw into a guitar body/nut and hold a Bass pickup or P90 against its supporting springs/Foam. Available in Nickel, Black or Gold.

A slightly strange screw in the grand scheme of things - most definitely
a #4 screw based on its thread, but with a #2 sized head.

Full Thread, slot head bolts used to mount a humbucker through the pickguard or mounting ring.
Available in Nickel, 33mm thread lengths
