Fixaball UNF 1/2" Socket Cap Screw High Tensile 12.9 Self Colour DIN912

For fine thread fastening applications, the Fixaball UNF 1/2" socket cap screw is produced in high tensile steel with a self-colour black finish. This Allen hex socket cap head fastener has a 1/2" UNF thread with 20 TPI and conforms to DIN 912, ISO 4762 and BS 2470, Series 1960.

Available in a range of lengths, it includes fully threaded and partially threaded options. The cylindrical cap head is tightened with a 3/8" hex key. The self-colour finish offers low corrosion resistance without further surface treatment and is suited to conditions with no exposure to moisture, often greased or oiled.
