Value Collection MP4563 M8 X 1.25 Flange Bolt 35mm

Product Description

The VALUE COLLECTION MP4563 is a smooth flange bolt designed for metric fastening applications requiring a broad bearing surface without a separate washer. Manufactured from Grade 10.9 alloy steel with a zinc-plated finish, this bolt delivers high tensile strength and corrosion resistance suited for demanding mechanical assemblies. The M8 x 1.25 thread pitch, 35 mm length under head, and 18 mm smooth flange diameter make it a direct-fit choice for JIS B 1189 compliant applications. Licensed tradespeople and mechanical assemblers working in automotive, industrial, and equipment maintenance will find this bolt a reliable hardware option.

This bolt is suited for metric fastening in residential and commercial mechanical assemblies, automotive components, and industrial equipment where a flanged bearing surface is required to distribute clamp load. The partial threading allows for a stronger grip in through-bolt and tapped-hole configurations. The zinc-plated finish provides moderate corrosion protection in indoor and light outdoor service environments. Sold in packages of 10 with a minimum order quantity of 1 package.

Key Features

• 18 mm smooth flange diameter distributes clamping load without a separate washer
• Grade 10.9 alloy steel construction provides high tensile and proof load strength
• Zinc-plated finish offers corrosion resistance for general-purpose service environments
• Conforms to JIS B 1189 fastener standard

Compatibility

Designed as a JIS B 1189 compliant smooth flange bolt for metric M8 x 1.25 threaded applications requiring a Grade 10.9 alloy steel fastener with a partially threaded shank.

Installation Notes

Installation should be performed by a qualified mechanic or assembler familiar with metric fastener specifications. Confirm the mating thread is M8 x 1.25 before installation to prevent cross-threading. Use a 12.73 to 13 mm hex drive tool for proper engagement. Apply torque values according to the equipment manufacturer specifications for Grade 10.9 metric fasteners; do not exceed the rated torque for the mating material.
