Value Collection MP4574 M10 X 1.5 Flange Bolt 40mm Grade 10.9

Product Description

The VALUE COLLECTION MP4574 is a smooth flange bolt designed for metric fastening applications requiring high strength and a clean bearing surface. Built from Grade 10.9 alloy steel with a zinc-plated finish, this bolt delivers reliable clamping force in demanding mechanical assemblies. It features an M10 x 1.5 thread, a 40 mm length under head, and a 35 mm threaded section, making it a partially threaded configuration. The integrated 22.3 mm smooth flange distributes load evenly across the mating surface, eliminating the need for a separate washer. Installed by machinists, millwrights, and general mechanical tradespeople, it conforms to JIS B 1189 standards.

This bolt is suited for metric mechanical assemblies in manufacturing, industrial equipment, and general fabrication environments where a smooth flange seating surface is required. The partially threaded shank provides a precise grip length for applications where thread engagement must be controlled. It is appropriate for use in both light-duty and medium-duty assemblies where Grade 10.9 tensile strength is specified. Sold in a package quantity of 10 with a minimum order quantity of 1.

Key Features

• M10 x 1.5 metric thread, partially threaded with 35 mm thread length
• 40 mm length under head for controlled grip length in precision assemblies
• 22.3 mm smooth flange distributes clamping load without a separate washer
• Grade 10.9 alloy steel construction for high tensile strength
• Zinc-plated finish provides corrosion resistance in general service environments
• Conforms to JIS B 1189 fastener standard

Compatibility

Designed as an OEM-style metric flange bolt for use in assemblies specifying M10 x 1.5 partially threaded smooth flange fasteners per JIS B 1189.

Installation Notes

Installation is performed using a 14.73 to 15 mm hex drive. Ensure mating threads are clean and free of debris before installation. Apply appropriate torque per the assembly specification for Grade 10.9 fasteners — do not exceed the rated clamp load. Inspect the flange seating surface for burrs or damage that could affect load distribution before torquing.
