Value Collection 427767MSC M12 X 1.75 Flange Bolt 70mm

Product Description

The VALUE COLLECTION 427767MSC is a smooth flange bolt engineered to metric DIN 6921 standards. It features an M12 x 1.75 thread with a 70 mm length under the head and 30 mm of partial threading. The integrated smooth flange distributes clamping load across a 26.6 mm diameter bearing surface, eliminating the need for a separate washer. Manufactured from Grade 10.9 alloy steel with a phosphate and oil finish, this fastener delivers high tensile strength and corrosion resistance suitable for demanding mechanical and structural assemblies. It is installed using a 15.73 to 16 mm hex drive.

This flange bolt is suited for metric fastening applications in industrial machinery, automotive assemblies, and structural fabrication where a smooth flange seating surface is required. The partial thread design allows controlled engagement depth in blind-hole applications and is appropriate for joints requiring precise preload. The DIN 6921 and DIN ISO 898-1 compliance makes it a standard choice for OEM and MRO use across manufacturing and maintenance environments. Minimum order quantity is 50 pieces; each unit is individually packaged.

Key Features

• M12 x 1.75 metric thread with 70 mm length under head

• Meets DIN 6921 and DIN ISO 898-1 fastener standards

Compatibility

Designed as an OEM-style metric flange bolt for use in machinery, automotive, and structural applications requiring DIN 6921 compliant M12 x 1.75 partially threaded fasteners with a smooth flange bearing surface.

Installation Notes

Install using a 15.73 to 16 mm hex wrench or socket driver. Confirm mating thread condition and clean fastener holes before installation. Do not exceed the preload limits appropriate for Grade 10.9 fasteners in the joint material. Follow applicable industry torque standards for M12 Grade 10.9 metric bolts as published by the fastener manufacturer or relevant DIN specifications.
