Value Collection 4553 M6 X 1 Smooth Flange Bolt 50 Pack

Product Description

The VALUE COLLECTION 4553 is an M6 x 1 metric smooth flange bolt designed for secure fastening in applications that require a broad bearing surface without a separate washer. The integrated smooth flange distributes clamping load evenly across the joint face, reducing the risk of surface damage or fastener pull-through. Manufactured from Grade 10.9 alloy steel with a zinc-plated finish, this bolt delivers high tensile strength and corrosion resistance. The length under head measures 20 mm, making it well-suited for medium-duty assemblies in mechanical, industrial, and equipment maintenance work. This package contains 50 bolts.

This bolt is commonly used in machinery assembly, automotive components, industrial equipment, and general metal fabrication where a metric M6 thread pattern is specified. The smooth flange face provides a clean seating surface without serrations, making it appropriate for applications where marring or loosening from vibration is a concern but a locking flange is not required. Technicians and maintenance professionals working to JIS standards will find this fastener a direct fit for compliant assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using the appropriate metric hex socket or wrench sized for the 9.78 to 10 mm drive. Ensure mating threads are clean and free of debris before installation. Follow the torque specifications defined by the equipment manufacturer or applicable engineering standards for Grade 10.9 hardware. Do not mix with non-metric or non-compliant fasteners in the same joint.
