Product description

This custom stainless steel threaded flange shaft integrates multi-step flange, external thread and internal serrated teeth in one-piece machining. CNC turning ensures high concentricity of stepped outer circle and thread; milling accurately forms the internal serrated structure to realize anti-slip torque transfer. At Chenrong Precision, we use thread gauges to verify thread accuracy. All critical dimensions are fully inspected after machining. Stainless steel material provides outstanding corrosion resistance, suitable for humid and harsh working environments. One-piece structure avoids assembly gaps and improves overall connection reliability.

Product Features

• Integrated multi-step flange design for stable positioning and assembly
• Precision external thread for reliable threaded connection
