Value Collection 815052PR M8x1.25x50mm Hex Cap Screw Gr8.8

Product Description

The VALUE COLLECTION 815052PR is a metric hex head cap screw designed for general mechanical fastening in industrial and trade applications. It features an M8 x 1.25 thread with a 50 mm length under the head and a 13 mm hex drive. The fastener is manufactured from Grade 8.8 steel, which provides a tensile strength suitable for medium-duty structural and machine assembly work. A zinc-plated finish delivers baseline corrosion resistance for indoor and light-exposure environments. The screw is partially threaded per DIN 931 and ISO 4014 standards, making it well suited for applications that require a shoulder or clamping length on the shank. Machinists, millwrights, and general maintenance mechanics are the typical installers.

This screw is used in metric-dimensioned mechanical assemblies across manufacturing, equipment maintenance, and structural fabrication. The partial thread geometry is particularly useful when bolting through flanges, brackets, or mating components where full thread engagement is not required or where the smooth shank must bear shear loads. Sold individually, but ordered in multiples of 50 units per supplier minimum order requirement.

Key Features

• M8 x 1.25 metric thread with 50 mm length under head for precise dimensional fit
• Grade 8.8 steel construction for reliable medium-duty tensile performance
• Zinc-plated finish provides corrosion resistance in indoor and light-duty environments
• Partially threaded shank per DIN 931 and ISO 4014 standards
• 13 mm hex drive compatible with standard metric wrenches and sockets

Compatibility

Designed as a standard metric replacement fastener conforming to DIN 931 and ISO 4014 specifications, compatible with any M8 x 1.25 threaded application requiring a partially threaded hex head cap screw.

Installation Notes

Installation is typically performed by machinists, maintenance mechanics, or millwrights using a standard 13 mm wrench or socket. Always verify thread engagement depth and mating material thread condition before installation. Do not exceed the load ratings appropriate for Grade 8.8 fasteners in the given joint configuration. Follow applicable industry standards for torque guidance based on joint type and lubrication condition.
