Value Collection 428047MSC M16 X 2 Flange Bolt 120mm

Product Description

The VALUE COLLECTION 428047MSC is a metric smooth flange bolt designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. This partially threaded hex-drive bolt features an M16 x 2.00 thread size with 50 mm of thread engagement and a 120 mm length under head. It is manufactured from Grade 10.9 alloy steel with a phosphate and oil finish that provides baseline corrosion resistance and consistent torque behavior during installation. The integrated smooth flange distributes clamping load across a wider bearing surface, reducing the need for a separate washer in many applications.

This bolt is suited for use in medium-to-heavy industrial assemblies where high tensile strength and controlled clamp load are required. Typical applications include machinery frames, structural steel connections, automotive subassemblies, and industrial equipment mounting. The partial thread geometry makes it appropriate for through-bolt applications where an unthreaded shank is needed to bear shear loads. It conforms to DIN 6921 and DIN ISO 898-1 standards, making it compatible with metric fastening specifications used across European and global manufacturing environments.

Key Features

• M16 x 2.00 metric thread with 50 mm thread length for positive engagement in heavy assemblies
• 120 mm length under head with partial threading to handle shear loads along the shank
• Grade 10.9 alloy steel construction provides high tensile and proof load strength
• Smooth flange distributes bearing load without requiring a separate flat washer
• Phosphate and oil finish resists corrosion and supports consistent installation torque
• Conforms to DIN 6921 and DIN ISO 898-1 for metric fastener dimensional and mechanical standards

Compatibility

Designed as a DIN 6921 compliant metric smooth flange bolt suitable for M16 tapped holes or nuts conforming to metric coarse thread standards in industrial and mechanical assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench sized for the 20.67 to 21.00 mm hex drive. Follow applicable DIN ISO 898-1 torque specifications for Grade 10.9 fasteners at the joint design load. Inspect mating threads and flange bearing surfaces for damage or contamination before assembly. Never reuse fasteners that show signs of galling, thread damage, or yield deformation.
