Machine Screw Threads

Machine style screw thread are used on Non-Wood attachments of the guitar.

Parts such as Switch & Pickup mounts, String Saddles, Jack Mounts and Knob set Screws commonly use machine screw threads.  Practically every other Part used have Wood style Guitar Screws.

Popular machine screw thread names are ISO, UTS, UNC, UNF and UNEF,

What do these identifiers mean?

The two most common thread identifiers are ISO (International Organization for Standardization) Metric and UTS (Unified Thread Standard) American/Canadian.  Additional designations are determined by TPI (Threads per Inch)

UN(C) - Coarse Thread
UN(F) - Fine Thread
UN(EF) - Extra Fine

There are older types of thread identifiers also still in use such as:

USS - Coarse Thread - United States Standard,
developed by the Navy

SAE- Fine Thread - Society of Automotive Engineers

Pitch of the thread is the other identifier.   Pitch combined with TPI is unique to each thread style.  TPI and Pitch differences are why a UTS nut won't screw onto an ISO thread of the approximate same size.

 Modern import guitars and some American made guitars use ISO Metric style screw threads. 

If replacing parts on an older or Vintage Guitar, check carefully before replacing.  A quick look at the existing Screws will reveal if the Guitar Thread used is Coarse, Fine or Extra Fine.

Guitars produced in the '70's and '80's can have both ISO and UTS style Screw threads on the same guitar.  

Wood (Sheet Metal) Screws

Manufacturers of Wood Screws use a Number System for sizing Screws.

This system standardizes Head size, Thread width, Shank diameter and TPI.

Vintage Telecaster Guitar Screw Threads and Sizes

Here are the Style and sizes of traditional Guitar screws used on Telecasters, Stratocasters and other Vintage guitars. 

When examining a Vintage Telecaster the big surprise is that most of the hardware mounted to wood was attached with Sheet Metal screws.  The original Screws were Chrome plate on Magnetic Steel and on later versions  were predominately Nickel Plating on Stainless Steel, not regular steel as most of today's screws.   Here are some of the Screws sizes used on early Telecasters.

  2. 4 - Neck Mounting Screws -   #8 x 1 3/4" Nickel Oval Head, Phillips
