Socket Countersunk Head Machine Screws are made to DIN standard 7991 and host a hexagonal recess. They can be driven using a hex wrench or insert bit.
The driving of this screw with a hex wrench or insert bit makes these screws more efficient than slotted screw products, as the hex socket drive has more resistance to cam-out, and can be used alongside power drivers, enabling faster installation and higher torque to be achieved.
Available from Fastenright in Steel grade 10.9, in A2 and A4 Stainless Steel, and in Brass, Aluminium or Titanium if required.
Socket Countersunk Screws to DIN 7991 are available from M2 to M36, with lengths ranging from 3mm onwards. Imperial and other threads (UNC, UNF, BSW and BSF) are also available.
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.
