Cheese Head Screw

A cheese head screw has a cylindrical head with a flat top and a slotted drive. It is used for general fastening in machine assembly.

A cheese head screw fastens small parts and sits in a slot for a flat screwdriver. It often takes a nut or a tapped hole of the same thread. It can be used in light duty work where a low head is needed.

This kind of screw is often made in steel, stainless steel or brass. The material choice affects corrosion resistance and strength.

This is a general guide to checking this kind of part. It says nothing about any supplier's parts.

Ask for a certificate of conformance and check the slot, thread and head dimensions on receipt. A mill test certificate can be requested for the material.
