Introduce

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.

Feature

The stainless steel machine screw has a plain finish and a pan head with a Phillips drive. The pan head has a flat top and short vertical sides with a rounded top edge. Machine screws are threaded fasteners that are typically used with nuts or drilled and tapped (threaded) holes.

• Although this isn’t always the case, most machine screws are fully threaded.
• Machine screws are usually stronger than many other screw types.
• Standard machine screws tend to be somewhat smaller than many other types of bolts and fasteners.
• Machine screws are typically designed with finer, more accurate threads than alternative fastener types.
• Machine screws are almost always blunt-ended (flat-tipped), unlike many other screw types which taper to a sharp point at the tip.
