• This Handheld Screw Machine Chuck features internal cavity with symmetrical clamping jaws and spring reset. Screws stay vertical during feeding, reducing misalignment, floating locks and stripped threads. Achieves reliable locking on assembly lines for sensitive components.
• The Automatic Screw Feeder Chuck allows tool replacement through modular clamp design. No threaded adjustments or repeated disassembly needed. Change between screw sizes or replace worn parts quickly, minimizing production line downtime.
• Heat processed 304 stainless steel construction. Rustproof, wear resisting and impact resisting. Maintains locking accuracy in high temperature or erosive environments. Technical specs: Material 304 stainless steel. Hardness HRC55. Chuck size 5.5mm.
• Accommodates screw diameter M2.8 to M3.0, nut diameter 4.7 to 5.1mm, screw length up to 21mm. Works with pan head, countersunk, self tapping and precise small screws. One chuck handles multiple screw types on mixed production lines.
• Unlike traditional chucks requiring frequent tightening that causes thread damage, this screw clamp prevents repetitive impacts. Extends lifespan of drivers, rails and spindle heads. Ideal for high volume screw locking operations where machine .
