A countersunk headed screw conforming with ISO 10642 or DIN 7991, requiring a hex key (otherwise known as an Allen key) to fit.

The head diameter is slightly larger than that of the equivalent DIN 965 Phillips or Pozi driven screw. UNBRAKO® branded and manufactured to be stronger than the other size for size high tensile versions. Includes a precision hex socket for maximum key engagement. Property class of 12.9.
