M12 x 45mm Unbrako Socket Head Csk Screw Full Thread in Black Oxide - ISO 10642 (DIN 7991)

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. Please note that due to the nature of the surface finish on Unbrako products, some surface corrosion may be evident. This does not affect the performance of the product. Property class of 12.9.
