Oval Head Machine Screw

An oval head machine screw is a screw with a domed head and a cross recess. It is used where a low profile head is wanted and the screw sits in a countersunk hole.

An oval head machine screw fastens metal parts or panels with a neat, low profile head. It often takes a nut and washer of the same thread and is driven with a cross recess screwdriver.

This kind of screw is often made in stainless steel 304, which gives good corrosion resistance for indoor and 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 a mill test certificate if the material grade matters. On receipt, check the head shape, the recess depth and the thread form.
