What is a socket button head cap screw?

A socket button head cap screw has a domed, smooth head that sits flush or slightly proud of the surface. It uses an Allen wrench (hex key) to tighten, offering a clean and low-profile appearance compared to hex head bolts.

Why use stainless steel for this screw?

Stainless steel is used because it resists corrosion and rust, which is important for engine components that can be exposed to heat and moisture. The polished finish also adds to its aesthetic appeal.

What does '5/16-18 UNC' mean?

This refers to the screw's thread specifications. '5/16' is the diameter in inches, '18' is the number of threads per inch, and 'UNC' stands for Unified National Coarse thread, a common thread standard.

This particular screw is a 5/16-18 UNC thread size with a length of .500 inches. It's made from stainless steel and features a polished finish.
