Value Collection 643030PR M8 Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643030PR is a metric hex head cap screw designed for general-purpose fastening in mechanical assemblies, equipment fabrication, and structural connections. Sized M8 x 1.25 with a 12 mm length under head, this screw is fully threaded from tip to bearing surface. It is manufactured from Grade 8.8 steel with a bright, uncoated finish. The 13 mm hex drive allows installation with standard metric wrenches or hex sockets. Grade 8.8 indicates a medium-high strength carbon or alloy steel fastener suitable for demanding load-bearing applications. This part conforms to DIN 933 and ISO 4017 standards, ensuring dimensional consistency across compatible metric hardware.

This screw is suited for use in industrial machinery, HVAC equipment frames, plumbing fixture mounting, electrical enclosure assembly, and general trade applications requiring a reliable metric fastener. The fully threaded design maximizes thread engagement across the full grip length, making it well suited for short-clamp-length joints. It is installed by mechanics, millwrights, HVAC technicians, plumbers, and electricians wherever a metric M8 fastener is specified. Minimum order quantity is 100 pieces per order.

Compatibility

Designed as a standard metric replacement or service fastener for any application specifying an M8 x 1.25 x 12 mm fully threaded hex head cap screw conforming to DIN 933 or ISO 4017.

Installation Notes

Install using a metric wrench or socket sized to the 13 mm hex head. Ensure mating threads are clean and free of debris before driving. Power down or de-energize any equipment before replacing fasteners on live assemblies. Do not exceed the rated load capacity of Grade 8.8 fasteners or substitute them in applications specifying a higher grade without engineering review.
