Value Collection 643623PR M8x1.25x14mm Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 643623PR 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 M8 x 1.25 thread pitch and 14 mm length under head make it suitable for medium-duty clamping and assembly work. A 13 mm hex drive allows installation with standard open-end, combination, or socket wrenches. This screw is used by maintenance technicians, millwrights, and mechanical contractors in production, repair, and assembly environments.

This fastener is appropriate for metric-threaded assemblies in industrial machinery, equipment frames, automotive components, and structural brackets. The fully threaded shank provides consistent thread engagement along the full length under the head, making it well suited for through-hole applications and thin-member clamping. Grade 8.8 steel provides a medium-high tensile strength suitable for a wide range of mechanical load applications where hardened fasteners are not required.

Key Features

• Grade 8.8 steel construction for reliable medium-high tensile strength
• Fully threaded shank for maximum thread engagement in through-hole applications
• Meets DIN 933 and ISO 4017 dimensional standards
• Bright uncoated finish suitable for indoor and controlled-environment use
• 13 mm hex drive compatible with standard metric wrenches and sockets

Compatibility

Designed as a standard metric replacement fastener for any M8 x 1.25 threaded application conforming to DIN 933 or ISO 4017 specifications.

Installation Notes

Install using a calibrated torque wrench or socket set sized for a 13 mm hex. Ensure mating threads are clean and free of debris before installation. Follow applicable engineering or equipment manufacturer torque specifications for Grade 8.8 M8 fasteners, as no torque value is specified in the product data. Power down or de-energize any equipment before performing fastener service on live assemblies.
