Iso7380 Button Head Hex Hexagon Socket Bolt

Iso7380 Button Head Hex Hexagon Socket Bolt

Button socket cap Screws feature a low profile, cylindrical head with a plain finish. The internal hexagonal drive hole, also known as a hex-socket drive, requires a hex socket wrench drive — commonly called an Allen wrench, hex key or Allen key driver — for quick and easy insertion. With its flush profile, button socket cap screws are ideally utilized in areas with little overhead or side clearance and suitable for light duty applications like machine assembly with removable parts and panels.
