Engineered for reliability in mechanically demanding setups, the Square Head Set Screw in Case Hardened Steel with a Cup Point delivers secure clamping and lasting performance. Designed for shafts and components where a low-profile drive head is preferred, this screw combines precision threading with a robust, wear-resistant finish.

With a 5/16-18 thread size and a length of 5 inches, these set screws are a versatile choice for a wide range of applications, from industrial machinery to DIY projects. The square head provides a flat driving surface that resists rounding, while the cup point ensures a firm, even seating to reduce marring on the mating surface.
