Value Collection 643501PR Hex Head Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION 643501PR is a metric hex head cap screw designed for general-purpose mechanical fastening in industrial, commercial, and trade applications. It features a fully threaded shank in M8 x 1.25 thread size with an 80 mm length under the head, and is manufactured from Grade 8.8 steel with a bright uncoated finish. Grade 8.8 steel provides a medium-high tensile strength rating suitable for structural and mechanical assemblies where a standardized metric fastener is required. The 13 mm hex drive allows installation with standard hex wrenches or sockets. This screw conforms to DIN 933 and ISO 4017 standards.

This hex head cap screw is used across a wide range of mechanical and structural assembly applications, including equipment fabrication, machinery maintenance, HVAC equipment mounting, and general trade work. The fully threaded configuration makes it well suited for through-bolting applications and short clamping lengths. It is installed by licensed tradespeople, millwrights, and maintenance technicians wherever a metric-standard cap screw is called for in Grade 8.8 service conditions.

Compatibility

Designed as a standard DIN 933 and ISO 4017 compliant metric hex head cap screw, suitable for any mechanical or structural assembly specifying an M8 x 1.25 x 80 mm Grade 8.8 fully threaded fastener.

Installation Notes

Installation should be performed by qualified tradespeople using appropriately rated metric hand tools or power drivers. Always ensure the receiving threads or nut are the same thread standard and pitch before driving. Do not exceed the rated load capacity for Grade 8.8 fasteners in the specific joint application. Fastener selection and torque requirements should comply with applicable mechanical or structural codes for the installation environment.
