Value Collection 4555 M6 X 1 Smooth Flange Bolt 30mm 25 Pack

Product Description

The VALUE COLLECTION 4555 is a smooth flange bolt in the M6 x 1 metric thread size, designed for bolted assemblies that require a built-in load-distributing flange face in place of a separate washer. The bolt is partially threaded with 20 mm of thread engagement and a total length under head of 30 mm. Constructed from Grade 10.9 alloy steel with a zinc-plated finish, it delivers high tensile strength and corrosion resistance suitable for industrial and mechanical applications. The smooth flange measures 14.2 mm in diameter. Drive is hex, with a drive size ranging from 9.78 to 10 mm. This fastener conforms to JIS B 1189. Each package contains 25 bolts.

This bolt is used in mechanical assemblies, light machinery, automotive components, and general industrial fabrication where metric fasteners are specified. The smooth flange bearing surface spreads clamp load across a wider area, reducing the risk of surface damage on softer substrates. Partially threaded shanks are preferred when a grip section is needed to control shear load or maintain bolt alignment through clearance holes. Licensed tradespeople, machine assemblers, and maintenance technicians working in metric environments will find this fastener appropriate for standard JIS B 1189 applications.

Key Features

• M6 x 1 metric thread with 20 mm thread length — partially threaded for shear-load control
• 30 mm length under head for adequate grip in common joint thicknesses
• Grade 10.9 alloy steel construction for high tensile and proof load ratings
• Smooth flange (14.2 mm diameter) distributes clamp load without a separate washer
• Zinc-plated finish provides baseline corrosion protection
• Conforms to JIS B 1189 fastener standard
• Sold in a 25-bolt package with a minimum order quantity of 1

Compatibility

Designed as a JIS B 1189 metric smooth flange bolt suitable for M6 threaded assemblies requiring a partially threaded hex-drive fastener with an integrated flange bearing surface.

Installation Notes

Installation is performed by machine assemblers or maintenance technicians using a standard hex wrench or socket sized to the 9.78 to 10 mm hex drive. Ensure mating threads are clean and free of debris before installation. Torque to the value specified by the joint design engineer or equipment manufacturer for Grade 10.9 M6 fasteners — do not rely on generic torque values without verifying joint requirements. Zinc plating provides light corrosion protection and is not a substitute for a heavy-duty coating in continuously wet or chemical environments.
