Key Features

Made from 42CrMo alloy steel (HRC 24-28°) for durability and wear resistance; 6H precision threads (M16×2) ensure smooth engagement with roller screws, minimizing backlash; Extremely low end-face runout (0.002-0.005mm) for stable axial positioning in high-accuracy applications.
Built-in copper setscrew provides extra locking force without damaging screw threads; Hexagonal shape allows easy tightening with standard wrenches (prevents rotation slippage).
Phosphate coating + lubrication reduces friction and resists rust in harsh environments; Ideal for CNC machines, 3D printers, robotics, and industrial automation.

Product Description

Premium Lock Nut for Roller Screw Systems This DN16 lock nut is designed for high-performance roller screw assemblies, offering zero backlash, high rigidity, and long service life.balances strength and machinability, while the phosphate coating and pre-lubrication enhance corrosion resistance and smooth operation. Key Advantages Copper Setscrew Design: The integrated soft copper locking screw prevents loosening under vibration, protecting your roller screw threads from damage. Hexagonal Shape: Fits standard wrenches for easy installation in tight spaces. Ultra-Precise Threads: 6H tolerance guarantees consistent fit with M16×2 roller screws (ideal for micro-adjustments). Low Runout Tolerance: Ensures even load distribution and reduces wear on screw assemblies. Applications  CNC machinery, linear actuators, and servo drives 3D printers, optical stages, and automation systems
