METRIC M22, THREAD PITCH 2.50 SOCKET HEAD CAP SCREW 12.9 COARSE ISO 4762 / DIN 912 SELF COLOUR

If you cannot find the required size, please get in touch as not all products are available online.

Socket Head Cap Screws are also known as SHCS, Allen screw or Allen bolt, or simply a cap screw. Conforming to ISO 4762 or DIN 912, the contact surfaces of this screw or bolt are protected from external damage. Generally manufactured with a partial thread beyond a certain length and nominal diameter combination, but occasionally some stock may include a fully threaded shank at the same combination.

Technical Info

  1. Conversion factors: 1MPa=1N/mm2 ; 1kgf=9.8N ; 1MPa=145 p.s.i. approximately

Thread height is approximately 0.6135p

  1. The self colour screw surface finish for self colour is “Black Oxide” after heat treatment.
  2. Metric thread: Grade 12.9 is 4g 6g thread class. Please refer to ISO 965 standard.
  3. The below specification is for coarse threads only.
  4. Suggested seating torque values, only apply to metric Grade 12.9 hex, socket head cap screws. The tightening torque will change, if fixing takes place with materials or surface finishes with variable fixing coefficient. The self colour table can only be applied to coefficient of friction in which the screw maintains its status, without any additional treatment after heat treatment and that the thread has anti-rustic oil protection.
  5. The data below should only be used as a reference guide. The proper torque can only be determined by analysing the design parameters which include temperature plating, lubrication, face material, washer type and condition of the mating threads. Short term tensile creep and stress relaxation should be considered for applications where the temperature exceeds 400⁰ F (204⁰C). Lower ductility, impact strength and fatigue life must be considered for screws subject to temperatures below -20⁰F (-29⁰C)
