Product Description
This stainless steel threaded knurled nut is precision machined from solid 304 stainless steel bar via CNC lathe processing. The outer surface features diamond knurl (hatch knurling) to increase friction for convenient hand tightening without extra tools. Precision internal thread ensures smooth assembly and reliable locking positioning.
Complete production workflow includes rough turning, precision thread cutting, diamond knurling, end facing and surface brushing. Final passivation treatment enhances anti-rust performance of stainless steel without altering metallic texture.
As a reliable OEM custom manufacturer, we deliver flexible custom service. Customers can provide drawings or samples to customize dimensions, thread specifications, knurl patterns and surface treatments. Widely used as knurled adjustment nut and camera lens lock ring across optoelectronics, precision instruments and automation assemblies.
