Value Collection 426995MSC M5 X 0.8 Flange Bolt 20mm

Product Description

The VALUE COLLECTION 426995MSC is a smooth flange hex bolt designed for metric fastening applications requiring a stable, load-distributing bearing surface. Built from Grade 10.9 alloy steel with a phosphate and oil finish, this bolt delivers high tensile strength with corrosion-inhibiting surface protection. The integrated smooth flange measures 11.8 mm in diameter, eliminating the need for a separate washer in many assemblies. At M5 x 0.8 thread pitch with 20 mm of thread length under the head, it fits a wide range of light-duty to medium-duty metal fabrication, automotive, and mechanical assembly applications. Installation is performed with a 7.78 to 8.00 mm hex drive.

This bolt is suited for use in mechanical assemblies, automotive subframes, brackets, and industrial equipment where a metric fastener with a built-in flange is specified. It conforms to DIN 6921 and DIN ISO 898-1 standards, making it appropriate for use in engineered assemblies with defined fastener grade requirements. Tradespeople in manufacturing, millwright work, and automotive service will recognize this as a standard metric flange bolt used in both OEM and aftermarket assembly scenarios. Sold individually, with a minimum order quantity of 100 units.

Compatibility

Designed for use in metric fastening applications requiring an M5 x 0.8 smooth flange bolt conforming to DIN 6921 dimensional standards and DIN ISO 898-1 mechanical property requirements.

Installation Notes

Installation is performed by machinists, automotive technicians, millwrights, or maintenance trades using a standard hex wrench or socket sized to the 7.78 to 8.00 mm drive. Always de-energize, depressurize, or lock out the assembly before fastener removal or replacement. Torque to the value specified in the equipment manufacturer documentation for M5 Grade 10.9 fasteners — do not substitute a lower-grade bolt in a Grade 10.9-specified joint. Inspect the mating threads for damage before installation.
