Value Collection 815139PR M12x1.75x70mm Hex Cap Screw

Product Description

The VALUE COLLECTION 815139PR is a metric hex head cap screw engineered for general industrial and mechanical fastening applications. Manufactured from Grade 8.8 steel with a zinc-plated finish, this screw delivers a balance of tensile strength and corrosion resistance suited for moderate-exposure environments. The M12 x 1.75 thread profile and 70 mm length under head make it a standard choice for bolted assemblies requiring partial threading. The 19 mm hex drive is compatible with common metric tooling. Conformance to DIN 931 and ISO 4014 standards ensures dimensional consistency and interchangeability across metric fastener specifications. Installation is performed by maintenance mechanics, millwrights, and general industrial trades.

This screw is appropriate for structural and mechanical assemblies in manufacturing, equipment maintenance, and fabrication settings. Its partially threaded shank provides a bearing surface between clamped components, which is preferred in applications where full thread engagement into the clamped material is not required or where shear loads are present. Grade 8.8 steel is widely used in non-safety-critical bolted joints across general machinery and structural steel applications.

Key Features

• M12 x 1.75 metric thread size conforming to DIN 931 and ISO 4014 standards
• 70 mm length under head with partial threading for bearing-surface bolted joints
• Grade 8.8 steel construction for reliable tensile and yield strength in general fastening service
• Zinc-plated finish provides baseline corrosion resistance for indoor and moderate-exposure environments
• 19 mm hex drive compatible with standard metric wrenches and sockets

Compatibility

Designed as a standard DIN 931 and ISO 4014 metric hex head cap screw for use in any assembly specifying an M12 x 1.75 partially threaded bolt with a Grade 8.8 strength rating.

Installation Notes

Install using a 19 mm metric wrench or socket. Power down and de-energize any equipment before accessing fastener locations on live machinery. Follow applicable equipment manufacturer torque specifications for M12 Grade 8.8 fasteners — do not substitute values not provided by the equipment OEM. Inspect the mating threaded bore for damage or contamination before installation.
