Value Collection 815243PR M12x1.25x30 Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 815243PR is a metric hex head cap screw designed for fastening applications that require a fine-pitch thread and reliable clamping strength. Built to Grade 8.8 steel with a zinc-plated finish, this screw delivers solid mechanical performance while resisting surface corrosion in general industrial and mechanical environments. It is fully threaded along its 30 mm length under head, providing consistent thread engagement throughout the fastened joint. The 19 mm hex drive allows installation with standard metric wrenches or sockets. This fastener conforms to DIN 961 and ISO 8676 standards, making it a direct fit for precision metric assemblies across manufacturing, maintenance, and repair operations.

This cap screw is suited for use in machinery assembly, equipment maintenance, and structural fastening where a fine-pitch M12 thread is specified. The fine 1.25 mm pitch offers improved resistance to vibration loosening compared to coarse-thread equivalents, making it a preferred choice in automotive, industrial, and OEM equipment applications. It installs in any setting where metric fasteners are called out by print or specification. Maintenance technicians, millwrights, and mechanical assemblers commonly source this screw for planned maintenance kits and equipment rebuilds.

Installation Notes

Installation is performed by mechanical assemblers or maintenance technicians using a 19 mm metric wrench or socket. Always ensure mating threads are clean and free of debris before installation. Apply thread-locking compound or washers as required by the equipment manufacturer or applicable assembly specification. De-energize and lock out equipment before replacing fasteners on live machinery.
