Value Collection 815355PR Hex Cap Screw M12x1.75 140mm Grade 8.8

Product Description

The VALUE COLLECTION 815355PR is a metric hex head cap screw designed for general industrial and mechanical fastening applications. It features an M12 x 1.75 thread profile with a 140 mm length under head, manufactured from Grade 8.8 steel with a zinc-plated finish for corrosion resistance. The shank is partially threaded per DIN 931 and ISO 4014 standards, with a 19 mm hex drive. Grade 8.8 designates a medium-high strength carbon steel fastener suitable for structural and machine assembly work. Zinc plating provides a barrier against oxidation in moderately exposed environments. Machinists, millwrights, maintenance technicians, and mechanical contractors install this type of fastener across a wide range of equipment and structural assemblies.

This screw is suited for metric-dimensioned assemblies in industrial machinery, fabrication, maintenance and repair operations, and general mechanical construction. The partial threading along the shank allows for precise clamping force distribution in bolted joint applications where a full-thread grip length is not required. It is commonly used wherever DIN 931 or ISO 4014 hex cap screws are specified on engineering drawings or equipment service documentation.

Key Features

• M12 x 1.75 metric thread size with 140 mm length under head
• Grade 8.8 steel construction for medium-high tensile strength
• Zinc-plated finish for corrosion resistance in moderately exposed environments
• Partially threaded shank per DIN 931 and ISO 4014 standards
• 19 mm hex drive for standard hex wrenches and sockets
• Metric thread standard for use in metric-dimensioned assemblies

Compatibility

Designed as a DIN 931 and ISO 4014 compliant metric hex head cap screw for use in M12 x 1.75 threaded applications requiring a partially threaded fastener.

Installation Notes

Installation should be performed by a qualified mechanic, millwright, or maintenance technician familiar with metric fastener torque requirements for Grade 8.8 hardware. Always verify thread engagement depth and hole condition before installation. Use a calibrated torque wrench and consult the equipment manufacturer's service documentation for specified torque values, as no torque specification is provided with this fastener alone. Inspect the zinc plating for damage before installing in corrosion-sensitive environments.
