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.

3. Optional different knurling patterns: diamond knurl, straight knurl
4. Multiple surface finishes: passivation, polishing, bead blasting
5. Support prototype trial orders and mass volume production
6. Provide custom labeling and packaging solutions

We are a professional custom manufacturer focusing on CNC precision turning metal parts.

Product Advantages

• Slipping when manually twisting? Deep uniform diamond knurl delivers stable friction for easy hand tightening.
• Stainless steel parts easily get rusty? Standard passivation treatment greatly improves corrosion resistance.
• Poor thread fit causing assembly jam? CNC precision threading fully inspected with thread gauges for consistent meshing.
• Hard to find manufacturers supporting small prototype batches? Our custom service accepts low-volume trial orders.
• Uneven end surface affecting fitting? Precision end turning + brushing ensures flatness for stable contact assembly.

Quality Control

1. Raw material verification of 304 stainless steel bar stock before production
2. In-process dimension sampling inspection during CNC turning, threading and knurling operations
3. Ultrasonic degreasing cleaning to eliminate metal debris inside threads and knurls
4. 100% thread inspection using go/no-go thread gauges
5. Final full inspection covering dimensional tolerance, surface appearance and knurl integrity
6. Batch inspection reports can be supplied on customer demand
