Binding Head Screw

A binding head screw is a machine screw with a rounded head that sits above the surface. It often has a slotted or cross recess drive and is used for general fastening.

A binding head screw secures materials by driving into a surface. It takes a nut of a matching thread and class.

This kind of screw is often made in stainless steel 304, which gives good corrosion resistance for indoor and some outdoor 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 and check the head marking, thread and finish on receipt. A mill test certificate can be requested for the material.
