Vented Socket Countersunk Screws

Vented Socket Countersunk Head Machine Screws, created to DIN 7991 specifications, have a hexagonal recess and are driven using a hex wrench or insert bit – making the screws more efficient than the slotted screw products, due to the hex socket drive having more resistance to cam out. They can also be used with power drivers, enabling faster use and higher achievable torque.

The vent in this screw would be to let air voids left from the fastener being threaded into a hole escape, avoiding a virtual leak.

Available in steel grade 10.9, A2 and A4 Stainless Steel, brass, aluminium and titanium, from M3 to M30, with larger diameters and lengths available as specials.
