Value Collection 427280MSC Flange Bolt M8 X 1.25 25mm Grade 10.9

Product Description

The VALUE COLLECTION 427280MSC is a smooth flange hex bolt designed for metric fastening applications requiring a broad-bearing surface without a separate washer. Manufactured from Grade 10.9 alloy steel with a phosphate and oil finish for corrosion resistance, this bolt features an M8 x 1.25 thread pitch and a 25 mm length under head with full threading throughout the shank. The integrated smooth flange measures 18 mm in diameter, distributing clamp load evenly across the mating surface. It is installed by maintenance technicians, machinists, and mechanical assemblers working to DIN 6921 and DIN ISO 898-1 standards.

This bolt suits general-purpose metric assembly in industrial, automotive, and equipment fabrication environments. Its fully threaded shank allows engagement along the entire fastened length, making it well suited for thin-material joints and close-tolerance assemblies. The hex drive accepts a 12.73 to 13 mm socket or wrench. Conformance to DIN 6921 and DIN ISO 898-1 makes it a direct fit in metric fastener specifications calling out those standards. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• M8 x 1.25 metric thread, 25 mm length under head, fully threaded shank
• Grade 10.9 alloy steel for high tensile strength in demanding assemblies
• Integrated 18 mm smooth flange distributes bearing load without a separate washer
• Phosphate and oil finish provides baseline corrosion and galling resistance
• Hex drive with 12.73 to 13 mm drive size for standard metric tooling
• Conforms to DIN 6921 and DIN ISO 898-1 fastener standards

Compatibility

Designed as a direct-fit replacement or standard supply item for metric assemblies specifying an M8 x 1.25 smooth flange bolt per DIN 6921. Suitable wherever the application requires a Grade 10.9 alloy steel metric flange bolt with a 25 mm grip length and full threading.

Installation Notes

Installation should be performed by qualified mechanical assemblers or maintenance technicians familiar with metric fastener torque specifications for Grade 10.9 hardware. Verify mating thread condition and clean the bore before installation. Do not mix with inch-standard hardware or Grade 8.8 fasteners where 10.9 strength is specified. Apply consistent torque using calibrated tooling to avoid yielding the bolt or distorting the flange.
