The AU-VE-CO PRODUCTS 15326 is a metric hex nut designed for general mechanical fastening applications across HVAC, plumbing, electrical, and equipment assembly work. It features an M5 x 0.80 thread size, manufactured from Grade 9 steel for high tensile strength, and finished with a phosphate coating that provides corrosion resistance and improved paint adhesion. The width across flats measures 10 millimeters, making it compatible with standard 10 mm wrenches and sockets. Tradespeople and equipment technicians use this nut wherever a compact, high-strength metric fastener is required. The phosphate finish also aids in lubrication retention, reducing galling during installation.
This hex nut is suited for residential and commercial mechanical assemblies, equipment mounting, panel fabrication, and general maintenance applications. It is appropriate for use in HVAC equipment assembly, electrical enclosure work, plumbing bracket installations, and similar trade scenarios where M5 metric fasteners are specified. This part is sold individually but carries a minimum order quantity of 50 units, making it practical for technicians who need a reliable supply on hand for recurring service work.
Designed as a standard M5 x 0.80 metric hex nut suitable for general mechanical and trade equipment assemblies requiring a Grade 9 steel fastener with phosphate finish.
Installation is performed by qualified tradespeople using a 10 mm wrench or socket driver. De-energize and isolate any equipment before fastener work on electrical or mechanical assemblies. Follow applicable equipment manufacturer torque guidelines and relevant codes such as NEC or IFGC where fastener specifications are referenced. Inspect threads for damage before installation to ensure proper engagement and clamping force.
