Square Head Set Screws
Set screws are often used to keep a pulley, gear, or similar disc-shaped object attached to a shaft. One advantage of a square head set screw over a socket set screw is that it is externally wrenched. With a socket set screw grease and dirt may pack into the broach and render it incapable of disassembly.

Various point styles are available on set screws. The choice depends on the application. Point choices include cup, knurled cup, flat, half dog, full dog, and cone.

Most of the square head set screws in inventory at Nickel Systems have a cup point. Our shop can readily modify existing parts to provide other point styles. Current inventory includes Hastelloy® (Alloys C276, C22, C2000), Alloy 20 (Carpenter 20®), AL6XN®, Nickel 200, 18-8, 316, 316L, and 317L Stainless.
