Value Collection 427117MSC M6x1 Flange Bolt 45mm Partial Thread

Product Description

The VALUE COLLECTION 427117MSC is a smooth flange bolt designed for high-strength metric fastening applications. This partially threaded bolt features an M6 x 1 thread pitch, a 45 mm length under head, and a 20 mm thread length. Manufactured from Grade 10.9 alloy steel with a phosphate and oil finish for corrosion resistance, it meets DIN 6921 and DIN ISO 898-1 standards. The integrated smooth flange distributes clamping load over a wider bearing surface, reducing the need for a separate washer. It is installed by licensed mechanics, millwrights, and industrial maintenance technicians working on machinery, automotive assemblies, and structural steel applications.

This bolt is suited for both light industrial and heavy-duty mechanical assemblies where precise metric fastening and consistent clamp load are required. The M6 thread size and 45 mm shank length make it a common choice in automotive subassemblies, equipment frames, and fabricated metal structures. The phosphate and oil finish provides baseline corrosion protection during storage and in moderate service environments. Minimum order quantity is 100 pieces, making this bolt well-suited for production and maintenance operations that require bulk fastener inventory.

Key Features

• M6 x 1 metric thread with 20 mm thread length - partially threaded shank for accurate load bearing
• Grade 10.9 alloy steel construction for high tensile and proof load strength
• Smooth flange with 14.2 mm flange diameter distributes clamping load without a separate washer
• Phosphate and oil finish provides corrosion inhibition and lubricity during installation
• Hex drive with 9.78 to 10 mm drive size for standard metric tooling
• Compliant with DIN 6921 and DIN ISO 898-1 fastener standards

Compatibility

Designed as a DIN 6921 standard smooth flange bolt suitable for metric M6 threaded assemblies in automotive, industrial machinery, and structural fabrication applications.

Installation Notes

Installation should be performed by qualified mechanics or maintenance technicians using calibrated metric hex tooling. Always verify thread engagement depth and mating thread condition before assembly. Grade 10.9 fasteners require appropriate tightening procedures per the applicable engineering specification for the assembly - do not substitute Grade 10.9 hardware with lower-grade fasteners without engineering review. Follow all applicable equipment manufacturer service procedures and relevant industry standards when installing in safety-critical assemblies.
