Unbrako Socket Head Countersunk Screws ISO 10642 M20mm in Black oxide high tensile steel class 12+

A countersunk headed screw conforming with ISO 10642 or DIN 7991, requiring a hex key (otherwise known as an Allen key) to fit. The countersunk head is typically used in conjunction with a countersunk hole providing a flush, snag free 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.
