Value Collection 643054PS M8x1.25 55mm Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643054PS is a metric hex head cap screw designed for general mechanical fastening applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fully threaded fastener meets DIN 933 and ISO 4017 standards. The M8x1.25 thread size with a 55 mm length under head makes it a common choice for machine assembly, equipment maintenance, and structural fastening tasks where a reliable, standardized metric fastener is required. The 13 mm hex drive allows installation with standard metric wrenches or sockets.

This screw is suited for use in manufacturing, maintenance, and repair operations across industrial and commercial settings. Typical applications include machinery assembly, fixture fabrication, and equipment repair where DIN 933 or ISO 4017 compliant fasteners are specified. The Grade 8.8 rating indicates medium-high tensile strength, appropriate for general structural and mechanical connections. This fastener is commonly installed by machinists, millwrights, maintenance technicians, and mechanical contractors.
