M8 304 SS Coupling Nut Pack

Pack of 50 M8 female-threaded coupling nuts, each cut from solid AISI 304 stainless steel billet using CNC turning and thread-rolling processes. Thread specification: ISO metric M8 × 1.25, Class 6H tolerance (tight fit for minimal play). Hex head measures 13 mm across flats, height 12 mm, typical density ~7.9 g/cm³ resulting in ~4.2 g per nut. No heat treatment beyond solution annealing — preserving optimal corrosion resistance and ductility. Unlike standard nuts, these coupling variants feature full-length internal threading with chamfered entry — easing initial rod insertion and guiding threads into engagement without binding. Their symmetrical geometry allows bidirectional use and simplifies inventory management, as orientation does not affect function. Load capacity is rated for static tensile loads up to 12 kN when paired with matching M8 Grade 8.8 rods — sufficient for most structural DIY and light commercial tasks. Frequently applied in retrofitting aluminium extrusion systems, extending flagpole sections, rebuilding bicycle rack mounts, anchoring acoustic panel frames, and assembling modular storage racks — wherever disassembly, adjustment or weather resilience is essential and visible hardware must remain visually clean and functional over time.
