Value Collection 4571 M10 X 1.25 Smooth Flange Bolt 25mm

Product Description

The VALUE COLLECTION 4571 is a smooth flange bolt designed for metric fastening applications where a built-in load-distributing flange eliminates the need for a separate washer. Threaded to the M10 x 1.25 pitch standard, the bolt features a 25 mm fully threaded shank measured under the head, delivering full thread engagement across the grip length. Manufactured from Grade 10.9 alloy steel, it provides high tensile strength suitable for demanding mechanical assemblies. A zinc-plated finish adds corrosion resistance for general-purpose indoor and light industrial environments. This bolt conforms to JIS B 1189, making it appropriate for applications requiring Japanese Industrial Standard compliance.

This bolt is used in mechanical, automotive, and industrial assembly work wherever a metric fine-thread flange bolt is specified. The smooth flange face seats cleanly against flat surfaces without serrations, making it suitable for assemblies where the clamped material must not be marred. The fully threaded design allows use across a range of stack-up thicknesses within the 25 mm shank length. Sold in a package quantity of 25, it suits bench stock, service kits, or low-volume production builds.

Key Features

• Grade 10.9 alloy steel construction for high tensile strength in demanding assemblies
• M10 x 1.25 metric fine thread for precise thread engagement and reduced vibration loosening
• Smooth flange face distributes clamp load without marring mating surfaces
• Fully threaded 25 mm shank provides maximum thread engagement flexibility
• Zinc-plated finish for corrosion resistance in general-purpose environments
• JIS B 1189 compliant for applications requiring Japanese Industrial Standard fasteners

Compatibility

Designed as an OEM-style metric flange bolt for use in mechanical and industrial assemblies specifying M10 x 1.25 fully threaded smooth flange bolts per JIS B 1189.

Installation Notes

Installation is performed by mechanics, millwrights, or maintenance technicians using a standard 14.73 to 15 mm hex drive. Verify thread engagement depth and mating thread condition before torquing. Apply fastener torque per the assembly specification for Grade 10.9 hardware. Do not mix metric fine-thread bolts with coarse-thread nuts or tapped holes.
