Machine Screws - Slotted Countersunk - BSW

A machine screw is a type of screw that is commonly used in industrial and manufacturing applications to secure components within engines, electronic products and general machinery.

Countersunk machine screws are designed for installation in countersunk holes to enable them to sit flush within the finished surface. This type of fastener should be installed with a flat-bladed screwdriver or bit.

They are available in zinc plated, brass and stainless-steel finishes.
