Slotted Spring-loaded Ball Plunger Set Screw with Steel Detent Ball-Slotted Positioning Screw

描述

1. Performance & Material Properties
   • Carbon & Alloy Steel Options: Available in quenched-and-tempered C1045 carbon steel (tensile strength ≈600 MPa, hardness 28–35 HRC) or 4140 alloy steel (tensile ≈800 MPa, hardness 40–45 HRC) for excellent shear and fatigue resistance.
   • Spring-Loaded Ball-Point Detent: Hardened bearing-steel ball (≈RC 55–60) captured on a precision spring delivers consistent preload forces (5–30 N, size-dependent) for repeatable positioning without marring mating surfaces.
   • Slotted Cylindrical Head: Ø 6–12 mm low-profile head with a wide slot provides slip-resistant engagement with standard flat-blade screwdrivers, enabling controlled torque application up to 10 Nm.
   • Protective Finishes: Choice of zinc-nickel plating (8–12 µm) for robust corrosion resistance or black-oxide coating for reduced glare and basic rust protection in industrial environments.
2. Detailed Application Range
   • Indexing & Detent Mechanisms: Ideal for jigs, fixtures, rotary tables, and machine-tool slides requiring a tactile “click-stop” feel for precise, repeatable positioning.
   • Latching & Locking: Secure doors, panels, movable guards, and access points in automation cells, packaging machinery, and heavy-duty equipment with a low-profile, snag-free head.
   • Sensor & Instrumentation Mounts: Maintain constant preload on optical benches, flow-control valves, camera mounts, and sensor assemblies in robotics, CNC stages, and test fixtures to resist vibration-induced drift.
   • Material-Handling & Conveyance: Act as end-stops, workpiece locators, and guide pins on conveyors, stamping presses, textile machines, and assembly lines without requiring additional detent plates.
3. Effortless Installation & Adjustment
   • Standard Slotted Drive: Wide slot accepts common flat-blade screwdrivers—no specialized Allen keys or torx drivers required—enabling rapid field service and setup.
   • Self-Contained Spring Mechanism: Built-in spring holds the detent ball in place throughout its travel, eliminating the need for external springs or washers and reducing assembly complexity.
   • Quick Servicing & Replacement: Metric thread sizes (M3–M12) screw in/out cleanly; ball-spring assemblies can be disassembled, cleaned, or replaced using standard hand tools, minimizing downtime.
4. Superior Quality & Long-Term Reliability
   • DIN 6325 / ISO 4026 & ISO 9001 Compliance: Manufactured to tight tolerances (±0.1 mm on thread OD, ±0.05 mm on ball diameter) in certified facilities, ensuring global interchangeability and precise fit.
   • Rigorous Testing: Every lot undergoes ball-preload verification, dimensional inspection, and ≥240 h salt-spray exposure per ASTM B117 (plated) or ISO 9227 (black-oxide) to guarantee consistent detent performance and corrosion resistance.
   • Full Traceability & RoHS Conformance: Material lot tracking from melt to finished part, backed by heat-treatment records and free of restricted substances and magnetic anomalies—delivering dependable, long-service life in the harshest environments.
