Value Collection 643372PR M8x1 20mm Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643372PR is a metric hex head cap screw engineered for precision fastening applications requiring fine-thread engagement. Sized at M8 x 1.00 with a 20 mm length under head, this screw is fully threaded along its entire shank, providing maximum thread engagement in tapped holes or with nuts. It is manufactured from Grade 8.8 steel in a bright, uncoated finish. The hex drive measures 13 mm across flats, accommodating standard metric wrenches and sockets. Licensed to DIN 961 and ISO 8676 standards, this fastener suits applications where dimensional consistency and mechanical strength are required. Machinists, millwrights, and general maintenance trades install these in assemblies calling for metric fine-thread hardware.

This fastener is suited for use in machinery, equipment frames, fabricated assemblies, and mechanical fixtures that specify M8 fine-pitch metric fasteners. The fully threaded configuration makes it particularly useful in thin-material applications or where full thread engagement along the bolt length is necessary. It conforms to DIN 961 and ISO 8676, making it interchangeable with other fasteners produced to those standards across metric-dimensioned equipment.

Key Features

• M8 x 1.00 fine-pitch metric thread, 20 mm length under head
• Fully threaded shank for maximum engagement in tapped holes
• Grade 8.8 steel construction for reliable mechanical strength
• Bright, uncoated finish — no coating buildup on thread flanks
• 13 mm hex drive fits standard metric wrenches and sockets
• Conforms to DIN 961 and ISO 8676 dimensional standards

Compatibility

Designed as a standard metric fine-thread hex head cap screw suitable for any tapped hole or nut conforming to M8 x 1.00 thread form per DIN 961 and ISO 8676 specifications.

Installation Notes

Installation is performed using a 13 mm wrench or socket; confirm the mating thread is M8 x 1.00 fine pitch before installation, as this pitch differs from the coarse M8 x 1.25 standard. Degrease or inspect the tapped hole for damage before threading in the fastener. Follow applicable torque specifications from the equipment manufacturer or relevant fastener standards for Grade 8.8 hardware. Minimum order quantity is 100 pieces.
