Value Collection 427727MSC M12 X 1.75 Flange Bolt 50mm

Product Description

The VALUE COLLECTION 427727MSC is a smooth flange bolt engineered for metric fastening applications requiring high-strength clamping in confined or load-distributing installations. Built to Grade 10.9 alloy steel with a phosphate and oil finish, this bolt provides reliable corrosion resistance and consistent torque performance. The M12 x 1.75 thread with a 50 mm length under head and 40 mm of partial threading suits a wide range of structural and mechanical assembly tasks. The integrated smooth flange — measuring 26.6 mm in diameter — distributes clamping load across the mating surface, eliminating the need for a separate washer in many applications.

This bolt is suited for industrial, mechanical, and structural assembly work where metric fastening standards are required. Partial threading provides a smooth shank section that supports precise alignment in clearance holes. The hex drive accepts standard metric wrenching tools. It conforms to DIN 6921 and DIN ISO 898-1 standards, making it appropriate for applications where certified fastener standards govern the installation. Typical users include machine builders, maintenance technicians, fabricators, and field service professionals working in metric-standard environments.

Key Features

• Grade 10.9 alloy steel construction for high tensile and proof load strength
• Smooth flange design at 26.6 mm diameter distributes clamping load without a separate washer
• Partially threaded shank with 40 mm thread length allows precise fit in clearance holes
• Phosphate and oil finish provides corrosion inhibition and lubricity for consistent torque values
• Conforms to DIN 6921 and DIN ISO 898-1 fastener standards
• Hex drive with 15.73 to 16 mm drive size compatible with standard metric wrenching tooling

Compatibility

Designed as a DIN 6921 compliant smooth flange bolt suitable for metric M12 x 1.75 fastening applications in mechanical assemblies, fabricated structures, and industrial equipment where Grade 10.9 strength class is specified.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using calibrated metric tooling appropriate for the 15.73 to 16 mm hex drive. Always degrease mating surfaces if lubrication-free clamping force values are required, noting that the phosphate and oil finish factors into friction-based torque calculations. Confirm thread engagement depth and hole clearance prior to torquing. Do not mix metric and unified thread fasteners in the same joint.
