Value Collection 643625PR M8 Hex Cap Screw Grade 8.8 Steel

Product Description

The VALUE COLLECTION 643625PR is a metric hex head cap screw designed for general mechanical fastening applications. It features a fully threaded shank with an M8 x 1.25 thread profile and an 18 mm length under the head. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fastener meets DIN 933 and ISO 4017 standards. The 13 mm hex drive size makes it compatible with standard metric wrenches and sockets. This screw is a common choice for machinists, maintenance technicians, and fabricators working with metric hardware in structural and machine assembly contexts.

This fastener is suited for a wide range of industrial and mechanical assembly applications where a fully threaded metric cap screw is required. It is appropriate for use in equipment maintenance, frame assembly, bracket mounting, and general machine building. The M8 x 1.25 thread size is one of the most common metric thread sizes, making this screw a practical stock item for shops, service fleets, and production facilities that work to metric standards.

Key Features

• Fully threaded shank for maximum thread engagement along the entire fastener length
• Grade 8.8 steel construction provides a balance of tensile strength and ductility for demanding mechanical applications
• Bright uncoated finish suitable for dry or lightly oiled installation environments
• Meets DIN 933 and ISO 4017 dimensional and mechanical standards

Compatibility

Designed as an OEM-style metric fastener replacement or stock component for any application requiring a fully threaded M8 x 1.25 hex head cap screw conforming to DIN 933 or ISO 4017 specifications.

Installation Notes

Installation is typically performed by machinists, maintenance technicians, or fabricators using a standard 13 mm metric wrench or socket. Always ensure mating threads are clean and free of debris before installation. Verify that the fastener grade is appropriate for the load requirements of the application before use. Do not exceed the rated mechanical limits of Grade 8.8 hardware in high-cycle fatigue or impact-load environments without proper engineering review.
