Value Collection 644127PR Hex Head Cap Screw M12x1.75x50mm

Product Description

The VALUE COLLECTION 644127PR is a metric hex head cap screw designed for general mechanical fastening applications. It features an M12 x 1.75 thread profile with a 50 mm length under the head and partial threading along the shank. Manufactured from Grade 8.8 steel with a bright, uncoated finish, this fastener meets DIN 931 and ISO 4014 dimensional standards. The 19 mm hex drive size is compatible with standard metric wrenches and sockets. This screw is a common choice for structural and machine assembly work where a medium-strength metric fastener is required.

This fastener is suited for a wide range of industrial, mechanical, and structural assembly applications. It is typically used in machinery, equipment fabrication, and general metalworking where metric fasteners conforming to DIN 931 or ISO 4014 are specified. The partial threading design allows the unthreaded shank to bear shear loads, making it appropriate for bolted joint assemblies where alignment and load transfer across the joint interface are important considerations.

Key Features

• M12 x 1.75 metric thread profile conforming to DIN 931 and ISO 4014 standards
• 50 mm length under the head with partial threading along the shank
• Grade 8.8 steel construction for medium-to-high tensile strength fastening
• 19 mm hex head size compatible with standard metric drive tools
• Bright, uncoated finish suitable for indoor or controlled-environment applications

Compatibility

Designed as a standard-dimension metric hex head cap screw per DIN 931 and ISO 4014, suitable for use wherever an M12 x 1.75 partially threaded hex bolt is specified.

Installation Notes

Installation should be performed by a qualified mechanic or assembler familiar with metric fastener specifications. Always verify thread engagement depth and joint design before installation. Use a calibrated torque wrench and apply the torque value specified by the equipment manufacturer or applicable engineering standard for Grade 8.8 hardware. Inspect threads and seating surfaces for damage or contamination before assembly.
