Category: Socket Flat Head Vent Screw

DIN 7991 hexagon socket cap screws feature a flat countersunk head and an internal hexagonal drive, making them suitable for use with a hex/Allen key or wrench. The internal drive is particularly advantageous in scenarios where externally wrenched screws are impractical, especially in applications with limited available space.

A vented screw is designed with a hollow core, featuring a hole drilled through it, to facilitate the release of gases, contaminants, and pressure through the fastener. Widely employed in vacuum systems, Vented Screws contribute to a quicker and more efficient pump-down process for HV, UHV, and EUV systems.
