Key Advantages Copper Setscrew Design: The integrated soft copper\nlocking screw prevents loosening under vibration, protecting your roller screw\nthreads from damage. Hexagonal Shape: Fits standard wrenches for easy\ninstallation in tight spaces. Ultra-Precise Threads: 6H tolerance guarantees\nconsistent fit with M8×1.25 roller screws (ideal for micro-adjustments). Low\nRunout Tolerance: Ensures even load distribution and reduces wear on screw\nassemblies.
