Value Collection 4581 M8 Flange Nut Zinc-plated 50-pack

Product Description

The VALUE COLLECTION 4581 is a metric M8 flange nut manufactured from steel with a zinc-plated finish. The integrated flange distributes clamping load over a wider bearing surface, reducing the need for a separate washer in most fastening applications. Key dimensions include a 17.5 mm flange diameter, 12 mm width across flats, and 8 mm height. Manufactured to JIS B 1190 standards, this nut is suited for general mechanical assembly, fabrication, and maintenance work where a reliable metric flange fastener is required. Each package contains 50 nuts.

This flange nut is appropriate for use in light to medium industrial and mechanical assembly applications. The M8 thread size is common in equipment panels, brackets, HVAC equipment frames, pump housings, and general sheet-metal assemblies. The zinc plating provides a basic level of corrosion resistance suitable for indoor and protected outdoor environments. Installers working on equipment requiring JIS B 1190 compliant hardware will find this nut a direct fit for standard M8 threaded fastener applications.

Key Features

• M8 metric thread size with 17.5 mm flange diameter for wider load distribution
• Steel construction with zinc-plated finish for basic corrosion resistance
• Meets JIS B 1190 fastener standard
• 12 mm width across flats fits standard metric wrenches and sockets

• Packaged in quantities of 50 for shop stock and service truck inventory

Compatibility

Designed as a standard JIS B 1190 compliant M8 flange nut for use with any M8 metric threaded bolt or stud in general mechanical, fabrication, or equipment assembly applications.

Installation Notes

Installation requires a standard 12 mm metric wrench or socket. Ensure mating bolt or stud threads are clean and free of debris before assembly. Do not exceed the torque rating of the base material or mating fastener. For applications in wet or corrosive environments, evaluate whether additional corrosion protection beyond the zinc finish is required.
