Button Head Cap Screws are very common in industrial applications. A cap screw is a fastener for machine parts, threaded along the whole length of its shank and held by threads tapped in the hole in which it is screwed. These screws provide high-torque capability and the drive system is a hexagon-shaped hole.
- Tighten with an Allen-style wrench
- Contains a recessed driving area and offers holding power at high torque levels
- Ideal for use in confined areas where the head needs to be flush or below the surface
