Hexagon Setscrews

A hexagon setscrew is a fully threaded fastener with a hex head, designed to be used without a nut by threading directly into a tapped hole or a threaded insert. At the DIY Hardware Store, our hexagon setscrews are available in the metric sizes used across engineering, machinery, and structural connections where a fully threaded fastener with a spanner-driven head is required.

The distinction between a setscrew and a bolt is that a setscrew is fully threaded from head to point, whereas a bolt has an unthreaded shank below the head. This makes setscrews the correct choice where thread engagement is needed along the full length of the fastener - in blind tapped holes, threaded insert connections, and any application where the fastener needs to develop clamping force along its entire length. Used extensively in machinery, gearboxes, motor mounts, structural steelwork, and general engineering. Available in zinc-plated and stainless steel at the DIY Hardware Store.
