Value Collection 427686MSC M12 X 1.75 Flange Bolt 25mm

Product Description

The VALUE COLLECTION 427686MSC is a smooth flange bolt designed for metric fastening applications requiring a high-strength, fully threaded connection. It features an M12 x 1.75 thread profile with a 25 mm length under head and a 26.6 mm smooth flange diameter that distributes clamping load across the mating surface without the need for a separate washer. Constructed from Grade 10.9 alloy steel with a phosphate and oil finish, this bolt delivers elevated tensile strength and corrosion resistance suited to industrial and mechanical assembly environments. It conforms to DIN 6921 and DIN ISO 898-1 standards. Licensed tradespeople and industrial assemblers working with metric-fastened equipment are the typical installers.

This flange bolt is used in mechanical, structural, and equipment assembly applications where a metric M12 fastening point calls for a smooth-flange head style. The fully threaded shank allows engagement along the entire bolt length, making it well suited for shorter through-bolt configurations and threaded insert applications. The phosphate and oil surface finish provides baseline corrosion protection for indoor and lightly exposed service environments. Minimum order quantity is 50 pieces; this listing covers a package quantity of 1.

Key Features

Compatibility

Designed for metric M12 x 1.75 threaded assemblies requiring a smooth flange head style per DIN 6921 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or assembler familiar with metric fastener torque requirements for Grade 10.9 hardware. Always verify thread engagement depth and ensure mating threads are clean and free of debris before installation. Do not mix metric and imperial fasteners in the same assembly. Follow applicable equipment manufacturer specifications and relevant industry standards for proper tightening procedure.
