Pan Head Screw

A pan head screw is a machine screw with a rounded top and a flat underside. It is used to fasten metal parts, often in electrical and electronic equipment. The head sits above the surface.

A pan head screw clamps two or more parts through a drilled hole. It takes a nut and often a washer of the same thread and class. It is turned with a slotted or cross recessed screwdriver.

Pan head screws are usually made in steel, stainless steel or brass. Steel is strong, stainless steel resists corrosion, and brass is used for electrical conductivity. Choose the material to suit the application.

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 screws. Check the thread with a gauge and the head dimensions. On receipt, inspect for burrs and correct recess type.
