These steel screws cut threads in drilled holes as they’re turned, so they require less driving torque and cause less stress on your material than thread forming screws.

A Torx drive has more points of contact than a Phillips drive, allowing you to apply extra force with less slippage or damage to the recess.

Made from 410 stainless steel, these screws are strong, wear resistant, and mildly chemical resistant.

These screws have a hex head for a secure grip with a wrench.

These metric thumb screws have arms that provide a flat surface to push your fingers against.

These metric thumb screws have wings that provide more leverage than spade-head thumb screws for greater torque while tightening. A zinc plating provides corrosion resistance in wet environments.

Mount these knobs into a threaded hole. They provide a secure grip to position, tighten, and hold fixtures, equipment, and machinery.

Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.

Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects.
