Cheese Head Screw

A cheese head screw is a machine screw with a slotted cylindrical head. It fastens metal parts and sits flat or slightly proud on the surface.

A cheese head screw fastens light parts and panels where a low, rounded head is wanted. The slotted head takes a flat screwdriver. It often matches a tapped hole or a nut and washer of the same thread.

This kind of screw is often made in brass, stainless steel 304 or stainless steel 316. Brass gives good machinability and moderate corrosion resistance. Stainless steel 304 suits general use.

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 for the material and dimensions. On receipt, check the slot for burrs, the thread for damage, and the head for cracks. Confirm the thread size and length match your order.
