Vented 6-Lobe Torx Countersunk Machine Screw

Our Vented 6 Lobe Torx Countersunk Machine Screws, to DIN 7985 with added vent, have a 6 lobular recess and is driven using a mating wrench or insert bit. This makes these screws much more efficient than slotted screws and hex socket drive screws.

Due to this, it has more resistance to cam out and can be used with power drivers enabling faster use and higher torque.

Manufactured from A2 / 304 Stainless Steel and A4 / 316 Stainless Steel as standard.

Available at Fastenright in thread sizes M4 to M8 as standard, with length from 4mm to 50mm.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.
