Value Collection 815521PR Hex Head Cap Screw M8 X 1.25

Product Description

The VALUE COLLECTION 815521PR is a metric hex head cap screw designed for general mechanical fastening in industrial, commercial, and trade applications. Manufactured from Grade 8.8 steel with a zinc-plated finish, this screw meets DIN 931 and ISO 4014 standards for partially threaded metric fasteners. It features an M8 x 1.25 thread profile, a 160 mm length under head, and a 13 mm hex drive. The zinc coating provides corrosion resistance suitable for typical indoor and light-duty outdoor environments. Machinists, millwrights, and general maintenance technicians install this type of fastener across a wide range of structural and mechanical assemblies.

This cap screw is suited for metric-dimensioned assemblies in manufacturing, equipment maintenance, and light structural applications. The partial threading is appropriate for clamping applications where a shoulder or grip length is required to span unthreaded material. It is commonly used in machine frames, brackets, flanges, and mechanical sub-assemblies where a standard metric coarse-thread fastener is specified. Minimum order quantity is 25 pieces.

Key Features

• Grade 8.8 steel construction provides a good balance of tensile strength and ductility for general fastening
• Zinc-plated finish offers basic corrosion resistance for indoor and sheltered environments
• Partially threaded shank allows the fastener to function as a shoulder bolt in clamping joints
• Conforms to DIN 931 and ISO 4014 standards for dimensional consistency and interchangeability
• 13 mm hex drive accepts standard metric hex sockets and wrenches

Compatibility

Designed as a standard metric replacement or stocking fastener for M8 x 1.25 coarse-thread applications conforming to DIN 931 and ISO 4014 specifications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance tradespeople using calibrated torque tools appropriate for Grade 8.8 metric fasteners. Always clean and inspect mating threads before installation. Do not exceed the recommended torque for the fastener grade and size as specified by engineering references or applicable standards. Replace any fastener showing corrosion, deformation, or thread damage.
