Value Collection 643547PR M4 Hex Head Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643547PR is a metric hex head cap screw engineered for general-purpose fastening in mechanical assemblies, fixtures, and fabricated components. It features an M4 x 0.70 thread with a 30 mm length under head, fully threaded shank, and a 7 mm hex drive. Manufactured from Grade 8.8 steel, this fastener meets the mechanical strength requirements defined by DIN 933 and ISO 4017. The bright, uncoated finish is suitable for indoor and dry-environment applications where coating is not required or where post-installation finishing will be applied by the installer.

This fastener is used in metric-dimensioned assemblies across industrial maintenance, light manufacturing, HVAC equipment mounting, electrical enclosure fabrication, and general mechanical work. The fully threaded shank makes it well-suited for shorter clamping lengths where full thread engagement is needed throughout the grip. It is commonly installed by maintenance technicians, millwrights, and equipment fabricators working to metric fastener standards.

Key Features

• M4 x 0.70 thread pitch, fully threaded shank for maximum engagement
• 30 mm length under head for standard metric fastening applications
• Grade 8.8 steel construction meets DIN 933 and ISO 4017 standards
• 7 mm hex drive compatible with standard metric wrenches and sockets
• Bright, uncoated finish for use in dry or controlled environments

Compatibility

Designed as a standard DIN 933 and ISO 4017 compliant metric hex head cap screw suitable for M4 x 0.70 threaded holes in mechanical assemblies and equipment.

Installation Notes

Install using a standard 7 mm metric wrench or socket driver. Ensure the mating thread is clean and free of debris before installation. De-energize or shut down any equipment before fastening components in electrical or mechanical enclosures. Do not exceed the rated mechanical load limits of Grade 8.8 fasteners in high-cycle or impact applications without engineering review.
