Value Collection MP4553 M6 X 1 Smooth Flange Bolt 25 Pack

Product Description

The VALUE COLLECTION MP4553 is a smooth flange bolt designed for metric fastening applications requiring a clean bearing surface and reliable clamping force. Threaded to M6 x 1 and measuring 20 mm in length under the head, this bolt features a 14.2 mm smooth flange diameter that distributes load without the need for a separate washer. Manufactured from Grade 10.9 alloy steel and finished with a zinc plating for corrosion resistance, it conforms to JIS B 1189 fastener standards. This bolt is driven by a hex drive and is suitable for mechanical assemblies, equipment mounting, and structural connections in metric-standard environments. Each package contains 25 bolts.

This smooth flange bolt is used in a wide range of trade and industrial applications where metric hardware is specified, including HVAC equipment assembly, mechanical enclosures, pump and motor mounting, and sheet metal fabrication. The smooth flange face is appropriate for use against finished surfaces or softer materials where a serrated flange could cause damage. Installation is suited for millwright, mechanical, and HVAC service work wherever JIS B 1189 compliant fasteners are required.

Compatibility

Designed as a JIS B 1189 compliant smooth flange bolt suitable for metric M6 threaded applications in mechanical, HVAC, and industrial equipment assembly where a load-distributing flange is required.

Installation Notes

Installation is performed by millwright, HVAC, or mechanical service technicians using standard metric hex sockets or wrenches sized to the 9.78 to 10 mm drive. De-energize and lock out all equipment before fastening or removing hardware in electrical or mechanical enclosures. Verify thread engagement and mating material compatibility before torquing. Do not use impact tools on Grade 10.9 fasteners without verifying that proper torque limits are observed per the equipment manufacturer's specifications.
