Value Collection 427946MSC M16 X 2 60mm Flange Bolt

Product Description

The VALUE COLLECTION 427946MSC is a smooth flange hex-drive bolt manufactured from Grade 10.9 alloy steel with a phosphate and oil finish. It features an M16 x 2 metric thread with 50 mm of thread engagement and a 60 mm length under head. The bolt is partially threaded and includes an integrated 35 mm smooth flange that distributes clamping load across the bearing surface without requiring a separate washer. This fastener meets DIN 6921 and DIN ISO 898-1 standards. It is installed by millwrights, maintenance mechanics, and industrial technicians in structural and mechanical assemblies requiring high-strength metric fasteners.

This flange bolt is suited for medium-to-heavy industrial applications where a controlled clamp load and a clean bearing surface are required. Typical uses include machine frames, equipment mounting, automotive subassemblies, and structural steel connections where metric fasteners conforming to DIN standards are specified. The Grade 10.9 strength rating makes it appropriate for high-stress joints in both OEM manufacturing and field maintenance settings.

Key Features

• M16 x 2 metric thread with 50 mm thread length for reliable engagement depth
• 60 mm length under head for versatile joint stack-up options
• Integrated 35 mm smooth flange eliminates the need for a separate flat washer
• Grade 10.9 alloy steel construction for high tensile and proof load capacity
• Phosphate and oil finish provides baseline corrosion resistance and lubricity
• Conforms to DIN 6921 and DIN ISO 898-1 for dimensional and mechanical compliance

Compatibility

Designed as a DIN 6921-compliant metric flange bolt for industrial and mechanical assemblies requiring M16 x 2 partially threaded fasteners with a smooth flange bearing surface.

Installation Notes

Installation should be performed by qualified mechanics or millwrights familiar with metric fastener torque specifications for Grade 10.9 hardware. Ensure mating threads are clean and free of debris before assembly. Apply torque with a calibrated torque wrench sized for the 20.67 to 21.00 mm hex drive. Do not use impact tools without a final torque verification, as over-torquing can stress the bolt beyond its proof load.
