Value Collection 428007MSC M16x2 90mm Flange Bolt Grade 10.9

Product Description

The VALUE COLLECTION 428007MSC is a metric hex flange bolt designed for high-strength fastening applications where a built-in flange provides load distribution without a separate washer. Sized at M16 x 2 with a 90 mm length under head and 50 mm of partial threading, this bolt meets DIN 6921 and DIN ISO 898-1 standards. Manufactured from Grade 10.9 alloy steel with a phosphate and oil finish for corrosion resistance, it is suited for mechanical assemblies, industrial equipment, and structural connections requiring reliable torque retention. Maintenance technicians, millwrights, and mechanical contractors are the typical installers.

This bolt is used in applications where a smooth flange bearing surface is required to distribute clamping load across a wider area than a standard hex bolt head. The 35 mm smooth flange diameter and 20.67 to 21.00 mm hex drive size make it compatible with standard metric tooling. Partial threading over 50 mm of the 90 mm shank length provides shank grip in through-bolt and clearance-hole installations. Typical applications include heavy equipment assembly, frame fastening, and industrial machinery maintenance where metric high-strength fasteners are specified.

Key Features

• Grade 10.9 alloy steel construction for high tensile and proof load strength
• Smooth flange eliminates need for a separate flat washer in many assemblies
• Partial threading retains an unthreaded shank for shear-load and clearance-hole applications
• Phosphate and oil finish provides baseline corrosion and galling resistance
• Meets DIN 6921 and DIN ISO 898-1 dimensional and mechanical standards
• Hex drive compatible with standard metric wrenches and sockets

Compatibility

Designed as an OEM-style metric replacement or service fastener for M16 x 2 threaded applications requiring a DIN 6921 smooth flange bolt with Grade 10.9 strength rating.

Installation Notes

Installation is performed by millwrights, mechanical contractors, or maintenance technicians using a standard 21 mm metric hex wrench or socket. Confirm mating thread condition and clearance hole diameter before installation. Apply appropriate torque per the assembly specification for Grade 10.9 M16 fasteners as outlined in the relevant engineering standard or equipment service manual. Clean and inspect mating surfaces before fastening to ensure full flange seating.
