Machine screws are typically designed with finer, more accurate threads than alternative fastener types. They are generally intended for use with a pre-drilled interior tapped hole or a nut. Machine screws are most often used for fastening metal parts securely together in various types of machinery or construction.A pan head screw is a machine screw with a large circular head that is slightly rounded on the top. It is free from pointed edges for safety and aesthetic purposes. They are also available from Accu with a larger head for a greater distribution of the load to avoid embedment. 

The stainless steel machine screw has a plain finish and a button head with a pin-in-star drive. Stainless steel resists corrosion and may be magnetic. The pin-in-star drive has a six-pointed indentation with a center pin that resists tampering by requiring a special driver to tighten or loosen the screw.
