Thompson Buttstock Screw

Thompson Buttstock Screw

This is a replacement wood screw for the buttstock of a Thompson submachine gun, made by United Defense. Reach for it when an original screw has stripped, gone missing, or had its slot chewed up by repeated removal. Owners restoring a Thompson, or keeping a shooter in working order, tend to keep a spare in the parts box.

Features

• Slotted Oval Head — A single straight slot across the head takes a standard flat-blade screwdriver.
• Countersunk Profile — The underside of the head tapers so it seats into a countersunk hole, a cone-shaped recess, and sits close to level with the surrounding surface.
• Coarse Wood-Screw Thread — Widely spaced, sharp-edged threads are cut to grip wood rather than a tapped metal hole.
• Gimlet Point — The tip is sharpened to a cone, which helps the screw start straight in its pilot hole.
• Smooth Upper Shank — An unthreaded section just below the head lets the screw draw the parts together snugly as it tightens.
• Black Finish — The head and threads carry a uniform black finish that suits dark metal hardware.
• United Defense Manufacture — A commercially made replacement part, so you do not have to hunt down an original to fill an empty hole.

Fit and Installation

The screw is made for the Thompson buttstock and drives into the wood with an ordinary flat-blade screwdriver. Use a blade that fills the slot fully, since a narrow or worn tip is the usual reason slotted heads get damaged. A hole that has already stripped may need repair before any new screw will hold firmly.
