Value Collection 42749 M8 X 1.25 Hex Socket Cap Screw 50 Pack

Product Description

The VALUE COLLECTION 42749 is a fully threaded hex socket cap screw in M8 x 1.25 metric thread, with a 20 mm length under head. Manufactured from alloy steel to material grade 12.9, it carries a black oxide coating for corrosion resistance. This fastener meets DIN 912 and ISO 898-1 standards, making it a reliable choice for high-strength bolted joints in mechanical assemblies, equipment frames, and structural connections. Installation requires a hex (Allen) key drive. This SKU ships in a 50-piece pack, suited for maintenance shops, production lines, and field service kits.

Grade 12.9 alloy steel socket cap screws are commonly used where high clamp loads and compact fastener heads are required. Typical applications include machine tool assemblies, hydraulic components, jigs and fixtures, and industrial equipment where access space is limited. The black oxide finish provides mild corrosion resistance in indoor and light-duty environments. These screws are installed by millwrights, maintenance technicians, and fabricators working to mechanical or structural assembly specifications.

Installation Notes

Installation is performed using a properly sized hex key or Allen socket driver rated for high-torque applications. Always verify that the mating threaded hole or nut meets the same metric standard and strength grade to avoid thread stripping or joint failure. Follow the torque specifications provided by the equipment manufacturer or applicable assembly standard, as no torque value is specified for this fastener in the available data. Inspect threads for damage before installation and do not use lubricants unless specified by the assembly procedure.
