½-13x1 Hex Head Cap Screw

Crafted from high-quality materials, this hex head cap screw from MSC Industrial Supply is plenty durable for demanding environments like machine shops.

For general machinery assembly and equipment maintenance, that size handles plenty of real work. The 1/2-13 threading is a common standard pitch, so it seats cleanly into most tapped holes and pairs up with standard 1/2-13 nuts without any fuss. The hex head means you can get a wrench or socket on it and put some actual torque to it, which makes it solid for assembly tasks where you need a fastener that stays put under load.

For a 1/2-13 threaded hole, you want a fastener with 1/2 inch diameter and 13 threads per inch, and that matches this cap screw. The length on this one is 1 inch, so it fits when that is the reach you need.
