Value Collection 644572PR Hex Head Cap Screw M5x0.80x45mm

Product Description

The VALUE COLLECTION 644572PR is a metric hex head cap screw designed for general industrial fastening applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fastener delivers reliable clamping strength in assemblies where a medium-strength metric bolt is required. The M5 x 0.80 thread profile and 45 mm length under head make it a standard choice for light mechanical assemblies, equipment fabrication, and maintenance work. It conforms to DIN 931 and ISO 4014 standards, confirming its partially threaded shank geometry and dimensional accuracy.

This screw is suited for use in metal fabrication shops, maintenance facilities, and production assembly environments where metric fasteners are specified. The partially threaded shank provides a bearing surface in the unthreaded portion, which is useful when fastening through clearance holes or in applications where the shank must span a joint without thread engagement throughout. The 8 mm hex drive accommodates standard metric wrenches and sockets commonly found in trade toolkits.

Key Features

• Grade 8.8 steel construction provides medium-high tensile strength for general mechanical fastening
• Partially threaded shank per DIN 931 and ISO 4014 for use in clearance-hole and through-bolt applications
• M5 x 0.80 mm thread pitch in standard metric sizing
• 45 mm length under head for appropriate grip range in light assemblies
• Bright uncoated finish suitable for dry or indoor environments
• 8 mm hex head drive compatible with standard metric wrenches and sockets

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 931 and ISO 4014 dimensional standards, suitable as a direct replacement or specification-grade fastener wherever an M5 x 0.80 x 45 mm partially threaded hex bolt is required.

Installation Notes

Installation is performed with a standard 8 mm open-end, box, or socket wrench. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated load for Grade 8.8 fasteners, and follow applicable engineering or equipment manufacturer torque specifications for the joint being assembled. Minimum order quantity is 100 pieces; plan procurement accordingly for production or maintenance stocking.
