Technical Specifications

Parameter	Key Details
Material	Brass (C36000/C37700/C26000: high corrosion resistance, excellent electrical conductivity, good machinability for precision threads)
Processing	CNC lathe turning, thread rolling/tapping, knurling, drilling, deburring, chamfering, polishing; customized for non-standard fastener geometries
Tolerance	Dimensional tolerance ±0.005–±0.02mm; thread tolerance 6g/6H (ISO standard); concentricity ≤0.01mm (ensures stable assembly and sealing)
Size Range	Screws/nuts: M1–M50 (metric), #000–2” (imperial); Rods: Diameter 2–100mm, length 10–2000mm; Pipe fittings: OD 4–150mm, thread types (NPT/BSP/UNC/UNF)
Surface Finish	Polishing (mirror finish for decorative applications), nickel plating, chrome plating (anti-tarnish, wear-resistant); passivation (enhances corrosion resistance in humid environments)
Mechanical Properties	Tensile strength ≥350 MPa; hardness 60–90 HRB; excellent thermal conductivity (110–120 W/m·K); operating temperature -20°C to 250°C
Compatibility	Fits hydraulic/pneumatic pipelines, electronic equipment, plumbing systems, marine hardware, and precision instrument assemblies; compatible with rubber gaskets and sealants for leak-free connections
