Pan Head Screw

A pan head screw is a machine screw with a rounded, slightly domed head and a cross recess drive. It fastens metal parts, brackets and panels where the head sits on the surface.

A pan head screw fastens metal, plastic and wood in light assemblies. It takes a nut or a tapped hole of the same thread, and a cross recess driver sets it. A washer can sit under the head, and a sems version carries its own.

This kind of screw is often made in brass, stainless steel 304 or stainless steel 316. Brass gives good corrosion resistance and electrical conductivity. Stainless steel 304 suits general indoor and outdoor use, while 316 offers better resistance to salt and chemicals.

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 to confirm the material and dimensions. On receipt, check the head shape, thread form and drive recess for damage. Confirm the material grade with a test certificate if the application is critical.
