Product Description

Product appearance features

These Finished Hex Nuts come with a standard six‑sided outer shape that works with common hand tools and power sockets. The flat sides are evenly spaced, so tools can lock on without slipping during installation. The top and bottom surfaces stay flat and parallel, making sure they sit evenly against the mating part when tightened. The central through hole has precise internal threads cut to standard inch or metric specifications, with no rough edges or uneven grooves that could affect thread engagement. Overall height matches industry dimensional rules, so they fit within set clearance spaces in assemblies without adding extra bulk. Corner edges are slightly broken instead of being sharp, reducing chances of scratching parts or injuring hands during handling. Width across the flats follows regular grade specifications, ensuring compatibility with standard socket sizes used in most production and repair work. Each unit maintains consistent shape from piece to piece, so there’s no unexpected variation when used in large‑scale assembly work.

Q&A session

What surface treatment methods can you offer for Finished Hex Nuts?

Available finishes include plain, zinc plated, and hot dip galvanized options. Each finish serves different corrosion resistance needs for various working environments. Zinc plating is widely used for general industrial applications, while hot dip galvanized versions suit more humid or outdoor installation conditions.

Product mechanical performance parameters

These Finished Hex Nuts follow SAE J995 and ASME B18.2.2 standards for mechanical performance. For Grade 5 types in sizes 1/4” to 1-1/2”, proof load stress hits 90,000 psi for plain finish and 68,000 psi after zinc plating, matching bolts up to Grade 5 without deformation under test loads. Hardness stays controlled at HRC 32 maximum, checked via standard rockwell tests to keep batch consistency. They go through quenching and tempering to stabilize internal structure, so hardness and load resistance do not drop in regular working temperatures. Thread stripping strength meets minimum requirements set by ASTM A563, lowering risks of thread failure when tightened to recommended torque values. Dimensional tolerance stays within ASME B18.2.2 limits, with flat width and thickness variations small enough for reliable tool engagement and consistent clamping force in assembly lines.
