Button Socket Head Cap Screws
Stainless Steel 304 (18/8)
Button head socket cap screws are precision threaded fasteners with an internal socket drive (also called allen hex drive) for installing in areas with limited side clearance. The internal hex drive requires an Allen wrench. They are known for their efficient application performance and endurance widely used in a variety of industries such as construction, manufacturing, engineering, assembling, aircraft and so on.
- For professionals, amateurs, landlords, repairmen and DIYers.
- These screws are available with a variety of head shapes, which determine how the screw interacts with the mating surface, and drive styles.
- Made of Stainless Steel 304 (18-8) which provides good strength and corrosion resistance in bad environments.
