Frequently Asked Questions

What is a thumb screw?

A thumb screw is a hand‑tightened fastener with a knurled head that allows tool‑free tightening/loosening.

Where is the 159760 thumb screw used?

It’s used in Graco assemblies where a 3/8‑16 UNC screw is specified, often for securing guards, brackets, or covers.

Can I replace it with a generic screw?

OEM screws ensure correct thread, fit, and strength — generic screws may not match tolerance or thread pitch and could damage the assembly.
