Value Collection 643034PR M8 X 1.25 X 20 Mm Hex Cap Screw

Product Description

The VALUE COLLECTION 643034PR is a fully threaded metric hex head cap screw conforming to DIN 933 and ISO 4017 standards. It features an M8 x 1.25 thread profile with a 20 mm length under head and a 13 mm hex drive. The fastener is manufactured from Grade 8.8 steel, a medium-carbon alloy heat-treated to provide a minimum tensile strength appropriate for structural and mechanical assemblies. The bright uncoated finish leaves the base steel exposed, which suits applications where a topcoat or locking compound will be applied after installation. Maintenance technicians, millwrights, and general assemblers are the primary installers of this hardware.

This cap screw is suited for metric mechanical assemblies across industrial, commercial, and light structural applications. It is commonly used in machine frames, equipment mounting, and general fabrication where a fully threaded M8 fastener is specified. The DIN 933 and ISO 4017 compliance ensures dimensional interchangeability with other metric hardware in the same standard family. Minimum order quantity is 100 pieces; each package contains 1 piece.

Key Features

Installation Notes

Installation is performed by mechanics, millwrights, or assembly technicians using a standard 13 mm metric wrench or socket. Verify that mating threads are clean and free of debris before assembly. Apply thread-locking compound or anti-seize as required by the application specification. Do not exceed the torque rating specified in the applicable assembly documentation for Grade 8.8 M8 fasteners.
