Cap headed socket screws are useful as an alternative to a hex head bolt where there is no space for a spanner. They have a high tightening ability due to their relatively large hex key size compared to other socket screw head types. Often called cap head socket machine screws or cap head bolts, they are used in much modern machinery. These are the fully threaded version and conform to DIN 912 (ISO 4762).

This set contains a comprehensive selection of  M3, M4, M5, M6 and M8 (3mm, 4mm, 5mm, 6mm & 8mm thread diameter) screws,
