Value Collection 427551MSC M10 X 1.5 Smooth Flange Bolt

Product Description

The VALUE COLLECTION 427551MSC is a smooth flange hex bolt manufactured to DIN 6921 and DIN ISO 898-1 standards. It features an M10 x 1.5 metric thread with a 35 mm length under head and a 22.3 mm smooth flange diameter. The bolt is made from Grade 10.9 alloy steel, placing it in the high-strength fastener category suitable for demanding mechanical assemblies. A phosphate and oil finish provides baseline corrosion resistance and lubricity during installation. The hex drive measures 14.73 to 15.00 mm across flats. This fastener is installed by machinists, millwrights, equipment technicians, and maintenance mechanics working on metric-threaded assemblies.

This bolt is suited for metric fastening applications in industrial machinery, automotive equipment, and mechanical assemblies where a built-in flange bearing surface is required to distribute clamping load without a separate washer. The smooth flange design seats evenly against flat surfaces, making it appropriate for sheet metal, stamped, and machined component joints. It is commonly used in production and MRO (maintenance, repair, and operations) settings where DIN-standard hardware is specified.

Compatibility

Designed as a DIN 6921 standard smooth flange bolt for metric M10 x 1.5 threaded applications in industrial, automotive, and mechanical assemblies where Grade 10.9 high-strength fasteners are specified.

Installation Notes

Installation should be performed by qualified mechanics or technicians familiar with metric fastener torque specifications for Grade 10.9 hardware. Always verify thread engagement depth and mating thread condition before installation. Use a calibrated torque wrench and follow the equipment manufacturer torque specifications for M10 Grade 10.9 fasteners. Do not mix metric and imperial hardware in the same joint.
