Value Collection 643058PR M8x1.25 Hex Cap Screw 70mm Grade 8.8

Product Description

The VALUE COLLECTION 643058PR is a fully threaded metric hex head cap screw designed for general-purpose mechanical fastening applications. Built to Grade 8.8 steel with a bright uncoated finish, this fastener meets DIN 933 and ISO 4017 dimensional standards. The M8x1.25 thread profile and 70 mm length under head make it well suited for medium-duty assemblies where reliable clamping force and dimensional consistency are required. The 13 mm hex drive allows installation with standard metric wrenches or sockets. Machinists, millwrights, equipment technicians, and general maintenance professionals commonly use this fastener in fabrication, machine assembly, and structural fastening work.

This screw is appropriate for use in industrial equipment assembly, mechanical fixtures, structural brackets, and general maintenance applications across commercial and light industrial settings. Its fully threaded shank provides thread engagement along the entire usable length, which is advantageous in thin material applications or where maximum thread contact is needed. The metric sizing conforms to ISO standards, making it a common choice in imported machinery and equipment with metric hardware specifications.

Key Features

• Grade 8.8 steel construction for consistent tensile and yield strength in medium-duty fastening
• Fully threaded shank per DIN 933 and ISO 4017 standards
• M8x1.25 metric thread profile for broad compatibility with standard metric hardware
• 13 mm hex drive compatible with standard metric wrenches and sockets
• Bright uncoated finish suitable for indoor and dry-environment applications
• 70 mm length under head for deeper engagement in thicker assemblies

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 933 and ISO 4017, suitable for use wherever an M8x1.25 fully threaded fastener is specified.

Installation Notes

Installation is performed by qualified mechanical technicians or maintenance professionals using a 13 mm metric wrench or socket. Ensure mating threads are clean and free of debris before installation. Apply thread engagement appropriate to the base material and consult relevant fastener standards for torque guidance specific to Grade 8.8 hardware. Do not use an impact driver without torque control, as overtorque can compromise fastener integrity.
