- Socket cap screws are precision fasteners often used in machine parts, die fixturing and clamping.
- A low head socket cap screw offers a reduced profile head height and uses a smaller drive recess.
- An internal hex socket drive is also known as an Allen drive.
- Alloy steel fasteners are significantly stronger than standard low carbon steel fasteners.
