Hillman 332222 1/4-20 X 3/8 Socket Head Set Screw – Cup Point, 100-Pack, Fully Threaded For Mechanical Applications

About This Product

If you need to lock a collar, gear, or pulley onto a shaft, these set screws are the answer.

They're 1/4-20 thread, 3/8 inch long, with a cup point that bites into the mating surface for a secure hold.

Headless and fully threaded, they sit flush or below the surface – perfect for tight spaces where a regular screw head would get in the way.
The socket head (hex drive) makes them easy to tighten with an Allen wrench, even in cramped spots.

You get a 100-pack, so you'll have plenty for mechanical assemblies, repairs, or hobby projects.
Hillman is a trusted name for hardware, and these are made to standard specs.
Solid, dependable, and priced right for bulk use.

Grab a pack and keep it in your parts bin.
