Product Feature :
Machine screws used to hold parts together in tools, appliances, machines, electronics, engines, and industrial manufacturing equipment. The threads remain the same diameter throughout the entire length. This is opposed to tapered threads with a pointed end which can cut their own thread into the materials, so mostly machine screws are threaded through pre-drilling, tapped holes. The most common head types of this kind of screw are round head, flat head, oval head, pan head, truss head, and hex head.
