Carbon Steel Hex Socket Spring Ball Point Grub Screw-Allen Socket Drive Spring Ball Plunger Screw

描述

1. Performance & Material Properties
   • Alloy Steel Construction: Bodies machined from quenched‐and‐tempered 4140 alloy steel (tensile strength up to ≈800 MPa, hardness 40–45 HRC) for maximum fatigue and shear resistance.
   • Hardened Ball & Spring: High-precision bearing steel ball (≈RC 55–60) captured on a spring tempered to deliver consistent preload forces (5–30 N, depending on size).
   • Protective Finish: Standard zinc-nickel plating (8–12 µm) or black-oxide coating for corrosion protection and reduced galling in industrial environments.
2. Detailed Application Range
   • Indexing & Positioning: Provide positive “click‐stop” detents in jigs, fixtures, rotary tables, machine tool slides and assembly stations for repeatable location.
   • Locking & Latching: Secure panels, doors, drawers and movable guards in automation cells, packaging machinery and medical equipment.
   • Component Holding: Apply constant preload on sensors, optical mounts, circuit-board holders, and end-effector attachments in robotics and instrumentation.
   • Assembly & Conveyance: Guide workpieces into precise stops on conveyors, stamping presses, textile machines and material-handling systems.
3. Effortless Installation & Adjustment
   • Internal Hex Drive: Recessed 2 mm–8 mm Allen socket ensures slip-free engagement and controlled torque (up to 15 Nm) for rapid insertion and withdrawal.
   • Self-Contained Spring Mechanism: No external spring or detent plate required—built-in spring retains the ball and provides uniform force throughout its travel.
   • Quick Servicing: Standard threaded body (M3–M12) screws in and out cleanly; ball assembly can be disassembled for cleaning or replacement without special tools.
4. Superior Quality & Long-Term Reliability
   • Precision Manufacturing: Produced in ISO 9001-certified facilities to DIN 1481/1480 tolerances (±0.1 mm on thread OD, ±0.05 mm on ball diameter) for interchangeability.
   • Rigorous Testing: Each lot undergoes ball-preload measurement, dimensional inspection and corrosion testing (240 h salt-spray per ASTM B117) to ensure consistent performance.
   • Full Traceability & Compliance: Material certification from melt lot to finished part; RoHS-compliant and free of magnetic anomalies—guaranteeing dependable operation in the most demanding applications.
