5.5mm Automatic Screw Feeder Chuck, Precision Clamp with Spring Reset for M2.8 M3.0 Screws, Quick Change Modular Design Stainless Steel Locking Chuck

1. Precise Alignment: This automatic screw feeder chuck features precise internal cavity with symmetrical clamping jaws and spring reset, ensuring screws remain vertical during use, it reduces misalignment, floating locks, and stripped screws, achieving 99.5% lock success rate 2. Applicable Range: This chuck accommodates M2.8-M3.0 diameter screws, 4.7-5.1mm nut diameter, and screw length up to 21mm. It works with pan head, countersunk, self tapping, and precise small screws, ensuring quick change for different screw types 3. Stainless Steel Material: Made from 304 stainless steel with a hardness of HRC55 after heat processing, this automatic screw machine chuck is rustproof, wear resisting and impact resisting. It maintains accuracy even in high temperature or erosive environments 4. Quick Change Design: The modular screw locking chuck allows quick replacement in under 10 seconds, significantly reducing production line downtime. The clamping mechanism eliminates the need for threaded adjustments or repeated disassembly 5. Reduce Equipment Wear: Unlike traditional chuck that requires frequent tightening and causes thread damage, this quick change screw clamp minimizes wear on machine components. It prevents repetitive impacts, extending the lifespan of drivers, rails, and spindle heads Specification: Item Type: Screw Machine Chuck Product Material: Stainless Steel Through Hole Diameter: Approx. 5.5mm / 0.22in Bit Hole Diameter: Approx. 4.0mm / 0.16in Chuck Total Length: Approx. 81mm / 3.19in Fit Screw Diameter: M2.8-M3.0 Fit Nut Diameter: Approx. 4.7-5.1mm / 0.19-0.2in Fit Screw Length: Approx. ≤21mm / 0.83in packing list: 1 x Handheld Screw Machine Chuck
