Stainless Steel 304 18-8 Hex Socket Spring Ball Point Grub Screw

描述

1. Performance & Material Properties
   • Premium 304 Stainless Steel Construction: Machined from AISI 304 (18-8) stainless steel and fully passivated for superior corrosion resistance in humid, marine, and chemical-exposed environments.
   • Spring-Loaded Ball-Point Tip: Hardened stainless ball (≈RC 50–55) captured in a captive spring delivers a consistent preload of 5–15 N, ensuring positive detent action without marring mating surfaces.
   • Mechanical Strength: Base screw body exhibits tensile strength ≈515 MPa and hardness ~80 HRB, providing reliable clamp force under static loads and repeated actuation cycles.
2. Detailed Application Range
   • Indexing & Detent Mechanisms: Ideal for jigs, fixtures, rotary tables, and adjustable stops in machine tools, allowing repeatable positioning with a positive “click” feel.
   • Automation & Robotics: Secure sensor mounts, end-effector tooling, and slide positioning in pick-and-place systems, conveyors, and CNC stages.
   • Instrumentation & Electronics: Apply precise preload in dial indicators, flow-control valves, camera mounts, and optical benches to maintain alignment under vibration.
   • Marine, Food & Medical Equipment: Corrosion-resistant spring action suits wash-down, hygienic processing lines, and non-magnetic medical assemblies.
3. Effortless Installation & Adjustment
   • Internal Hex Drive: Recessed Allen socket (1.5 mm–8 mm) for slip-free engagement and precise torque control (1–10 Nm), minimizing cam-out and operator fatigue.
   • Self-Setting Spring Ball: No need for supplemental springs or detent plates—built-in spring applies constant force, simplifying assembly and reducing part count.
   • Quick Repositioning & Removal: Ball compresses smoothly for adjustment or removal with standard hex keys, cutting maintenance and setup time.
4. Superior Quality & Long-Term Reliability
   • Tight Tolerances & Certification: Produced in ISO 9001–certified facilities to DIN 916 (ISO 4026) tolerances (±0.1 mm), ensuring interchangeability and precise fit.
   • Rigorous Testing: Each lot undergoes dimensional inspection, drive-torque consistency checks, and ≥240 h salt-spray exposure per ASTM B117 for passivated stainless surfaces.
   • Full Traceability & Compliance: Material lot tracking from melt to finished part; RoHS-compliant and free of magnetic anomalies, guaranteeing dependable performance in the most demanding applications.
