M3 M4 M5 M6 M8 M10 M12 304 stainless steel extended cylindrical Knurled Thumb Nut Mesh Link Adjustment Nut
Mea waiwai
This extended cylindrical knurled thumb nut is crafted from high-grade stainless steel (e.g., 304 or 316), offering exceptional corrosion resistance, durability, and mechanical strength. The stainless steel composition ensures long-term performance in harsh environments, including exposure to moisture, chemicals, and extreme temperatures, making it ideal for both industrial and outdoor applications.
Manufacturing Process
The nut is precision-machined using CNC turning to achieve a smooth cylindrical shape and precise internal threading. The knurled surface is then added through a rolled knurling process, creating a diamond or straight pattern for enhanced grip during manual tightening. Finally, the component undergoes electropolishing or passivation to remove surface impurities and improve corrosion resistance while maintaining a clean, polished finish.

Designed for tool-free adjustments, this thumb nut is widely used in:
Electronics: Securing panels, connectors, and heat sinks in devices requiring frequent maintenance.
Medical Equipment: Assembling sterilizable instruments and adjustable mounts in hygienic environments.
Automotive & Machinery: Fastening components in tight spaces where manual operation is preferred.
Consumer Products: Furniture assembly, camera tripods, and DIY projects needing ergonomic, user-friendly fastening solutions
