What is an Allen CSK Bolt?

An Allen CSK Bolt (Allen Countersunk Bolt) is a type of fastener with a flat, conical head designed to sit flush with the surface when installed. It features an internal hexagonal (Allen) socket that allows tightening using an Allen key (hex key). These bolts are commonly used in applications where a smooth and seamless finish is required, preventing protrusions that could cause obstructions or safety hazards.
