Value Collection 4554 M6 X 1 Smooth Flange Bolt 25mm Zinc-plated

Product Description

The VALUE COLLECTION 4554 is a partially threaded smooth flange bolt designed for metric fastening applications requiring a larger bearing surface and a clean, low-profile seating area. Built from Grade 10.9 alloy steel with a zinc-plated finish, this bolt delivers high tensile strength and corrosion resistance in a single fastener. The integrated smooth flange eliminates the need for a separate washer, distributing clamp load evenly across the mating surface. With an M6 x 1.00 thread, 25 mm length under head, and 20 mm of thread engagement, it suits a range of light structural and mechanical assembly tasks. Sold in packages of 25.

This bolt is suited for mechanical assemblies, light structural connections, and equipment fabrication where metric fasteners are specified. The smooth flange design is commonly used in automotive, industrial machinery, and general manufacturing applications where load distribution and surface contact consistency are important. The hex drive configuration is compatible with standard metric hex wrenches and sockets. Installation is typically performed by millwrights, assembly technicians, and mechanical tradespeople working to JIS B 1189 fastener standards.

Key Features

• Grade 10.9 alloy steel construction for high tensile strength in demanding fastening applications
• Smooth flange with 14.2 mm diameter provides a built-in bearing surface, eliminating a separate washer
• Zinc-plated finish offers corrosion resistance for general indoor and light industrial environments
• Partially threaded shank with 20 mm thread length on a 25 mm length-under-head body
• Hex drive with 9.78 to 10.00 mm drive size for use with standard metric hex tooling
• Conforms to JIS B 1189 fastener standard

Compatibility

Designed as an OEM-style metric flange bolt for applications specifying M6 x 1.00 partially threaded hex flange fasteners per JIS B 1189.

Installation Notes

Installation is performed by qualified mechanical tradespeople or assembly technicians using appropriate metric hex wrenches or sockets. Always verify thread engagement depth and mating material compatibility before installation. Do not exceed the torque range specified by the equipment manufacturer for Grade 10.9 M6 fasteners. Inspect zinc plating for damage before use in environments where corrosion resistance is critical.
