Carbon Steel Flange Spring Ball-Plunger Set Screw with Retractable Detent Ball

描述

1. Performance & Material Properties
   • Carbon Steel Flange Body: Machined from quenched-and-tempered C1045 steel (tensile strength ≈600 MPa, hardness 28–35 HRC) for robust static clamp force under heavy loads.
   • Alloy-Steel Detent Ball & Spring: Hardened bearing-grade steel ball (≈RC 58–62) retained by a precision spring calibrated to deliver consistent preload forces (10–40 N, size-dependent) and smooth retraction.
   • Flanged Head Design: Integral flange (Ø 8–16 mm) provides a broad seating surface for secure mounting and prevents over-insertion, while maintaining a low profile above the installation plane.
   • Protective Plating: Standard zinc-nickel (8–12 μm) or black-oxide finish offers enhanced corrosion resistance (≥240 h salt-spray per ASTM B117) and reduced galling in industrial environments.
2. Detailed Application Range
   • Indexing & Location Control: Ideal for positive “click-stop” detents in jigs, fixtures, rotary tables, and adjustable stops on machine tools, ensuring repeatable positioning under vibration.
   • Latching & Locking: Secure panels, doors, sliding guards, and access covers in automation cells, packaging machinery, and material-handling equipment with a retractable ball that locks firmly when engaged.
   • Sensor & Instrumentation Mounting: Maintain constant preload on optical mounts, flow-control valves, camera fixtures, and end-effector tooling in robotics and CNC systems to resist drift under dynamic motion.
   • Conveyor & Assembly Lines: Act as end-stops, workpiece locators, and guide pins on conveyors, stamping presses, and assembly fixtures—eliminating the need for separate detent plates or springs.
3. Effortless Installation & Adjustment
   • Internal Hex Drive: Recessed Allen socket (2 mm–6 mm) enables slip-free engagement and precise torque control (up to 12 Nm), reducing cam-out and operator fatigue.
   • Self-Contained Spring Mechanism: No external washers or detent plates—built-in spring holds the ball in place and allows smooth retraction for quick component release or repositioning.
   • Flange Seating & Stop Feature: Flanged head seats flush against mounting surface to prevent screw over-travel and simplify alignment, while standard metric threads (M3–M10) screw in/out cleanly for rapid maintenance.
4. Superior Quality & Long-Term Reliability
   • DIN 2105 / ISO 2338 Compliance: Manufactured to strict DIN and ISO tolerances (±0.1 mm on thread OD, ±0.05 mm on ball diameter) in ISO 9001-certified facilities, ensuring global interchangeability and precise fit.
   • Rigorous Quality Control: Each lot undergoes dimensional inspection, ball-preload verification, drive-torque consistency checks, and ≥240 h salt-spray testing to guarantee uniform performance.
   • Full Traceability & RoHS Conformance: Material batch and heat-treatment records maintained from melt to finished part; free of restricted substances and magnetic anomalies—delivering dependable, long-service life in the harshest operating conditions.
