Value Collection 4556 M6 X 1 Smooth Flange Bolt 35mm 25 Pack

Product Description

The VALUE COLLECTION 4556 is a smooth flange bolt designed for metric fastening applications requiring a clean bearing surface and positive load distribution. Manufactured from Grade 10.9 alloy steel with a zinc-plated finish, this bolt meets JIS B 1189 standards for dimensional accuracy and mechanical performance. The M6 x 1 thread with a 35 mm length under head and 20 mm of partial threading makes it well suited for assemblies where a grip length is required before thread engagement begins. The 14.2 mm smooth flange diameter spreads clamping force across a wider area without the need for a separate washer. Sold in a pack of 25 individual fasteners.

This bolt is used across a broad range of mechanical, industrial, and equipment assembly applications where metric JIS-standard fasteners are specified. It is commonly installed in sheet metal assemblies, light structural brackets, and equipment panels where controlled clamping and vibration resistance matter. The zinc-plated finish provides baseline corrosion protection suitable for indoor and sheltered environments. Technicians and maintenance professionals working on machinery, HVAC equipment frames, or fabricated steel assemblies will find this fastener a direct-fit option wherever an M6 x 1 partially threaded smooth flange bolt is called out on a parts list or engineering drawing.

Key Features

• 14.2 mm smooth flange diameter distributes clamping load and eliminates the need for a separate washer
• Zinc-plated finish offers corrosion resistance for general indoor and sheltered use
• Conforms to JIS B 1189 fastener standard for dimensional and mechanical compliance
• Sold in a 25-piece pack to support batch work and inventory replenishment

Compatibility

Designed as a standard metric replacement or service fastener for any assembly specifying an M6 x 1 partially threaded smooth flange bolt per JIS B 1189.

Installation Notes

Installation is performed with a 9.78 to 10 mm hex drive and should follow the torque specifications outlined in the applicable equipment service documentation for Grade 10.9 M6 fasteners. Ensure mating threads are clean and free of debris before installation. For structural or safety-critical joints, verify that the selected fastener grade matches the joint design requirements before torquing to final value.
