A socket head cap screws are machine screws with a cylindrical barrel shaped head containing a hexagonal socket. The head has a smaller diameter than most other machine screw heads, typically just 1.5 times the nominal thread diameter.
Low head cap screws are same as socket head cap screws that feature a head containing a hexagonal socket. The socket head makes it easy to securely install the screws with hex keys or hex socket bits, while their low head makes them suitable for installation in situations where there is limited clearance.
The Flat head screws have a large head and a cylindrical shaft with external threads. The head has a larger diameter than the threaded portion, this provides a positive mechanical stop when tightening the screw. Cap screws are tightened directly into a threaded or tapped hole, usually without a nut.
The Button head cap screws have a low domed type head with a wider bearing surface than standard heads. Designed for light fastening applications, button head cap screws lack the strength of standard socket screws.
This socket shoulder screw, often called a “stripper bolt”, is used for a wide range of punch and die operations. The shoulder screws are commonly used as fulcrums or pivots in machine designs that involve links, levers or other oscillating parts.
