Anti-Slip Knurl Hand Tightening Screws with High-Strength Structure and CNC Precision Machining for Industrial Tooling

Anti-Slip Knurl Hand Tightening Screws are professional precision positioning fasteners specially designed for industrial tooling fixtures and jigs. Manufactured with high-quality carbon steel or 304 stainless steel through cold heading and CNC precision machining, these knurled screws feature uniform anti-slip knurl patterns for tool-free manual tightening and loosening. With precise thread tolerance, stable clamping force and excellent anti-loosening performance, they are ideal for frequent fixture adjustment, positioning and quick mold change scenarios. Available in standard stock sizes and custom OEM sizes, they are widely used in automation jigs, testing fixtures and industrial positioning equipment.

• Anti-slip Knurl Design for Efficient Tooling Adjustment: The precise straight knurled head greatly increases surface friction, effectively preventing hand slipping during frequent fixture debugging and positioning. No wrenches or tools are required, enabling fast manual clamping, loosening and fine adjustment. It significantly improves working efficiency for tooling replacement, equipment debugging and workpiece clamping, perfectly suitable for high-frequency assembly line operation.
• High-Strength Structure for Stable Positioning & Clamping: Adopting cold heading forming technology, the screw features dense internal structure, high tensile strength and strong torsion resistance. CNC precision machining ensures standard and smooth threads with tight fitting clearance. Optimized for vibrating and continuous clamping working conditions, the screw avoids thread slipping and loosening after long-term repeated use, maintaining stable fixture positioning accuracy and consistent processing quality.
• Industrial Durability for Harsh Workshop Conditions
• Wide Compatibility & Customization Service

• Quick adjustment fasteners for automation jigs and testing fixtures
• Precision limiting and clamping parts for machining equipment workpieces
