DIN551 Headless Grub Screw-Carbon Steel Slotted Set Screw with Flat Point

描述

1. Performance & Material Properties
   • Carbon Steel Construction: Manufactured from high-carbon steel (e.g., C1045) quenched and tempered to achieve tensile strengths of 600–800 MPa and Rockwell hardness of 28–40 HRC for robust clamping under static loads.
   • Black-Oxide Finish: Uniform black-oxide coating (5–10 µm) provides basic corrosion resistance, reduced glare, and improved lubricity for smoother torque application.
   • Flat-Point Tip Design: Precisely turned flat end spreads clamp force evenly over mating surfaces, minimizing shaft marring while maintaining consistent holding power.
2. Detailed Application Range
   • Shaft and Collar Locking: Secure pulleys, collars, gears, and couplings on motor, gearbox, and conveyor shafts without deep indentations or misalignment.
   • Machine Tool Fixtures: Fasten stops, gauges, and adjustable guides on milling machines, lathes, and drilling fixtures where low-profile contact is required.
   • Instrumentation & Control Panels: Anchor circuit-board standoffs, sensor mounts, and optical components in test rigs and control cabinets.
   • General Industrial Assemblies: Ideal for jigs, dies, and assembly fixtures in automotive, packaging, and material-handling equipment.
3. Effortless Installation & Operation
   • Slotted Drive Interface: Standard slot head allows use of common flat-blade screwdrivers for rapid installation and field adjustments—no special hex wrenches needed.
   • Headless, Low-Profile Design: Fully recessed in tapped holes to eliminate protrusion and interference, keeping assemblies streamlined and snag-free.
   • Self-Seating Flat Point: Creates a micro-imprint on mating surfaces to resist loosening under vibration, yet can be repositioned or removed easily without damage.
4. Superior Quality & Long-Term Reliability
   • DIN 551 / GB 73 Standard Compliance: Produced to strict dimensions and tolerances (±0.1 mm) specified by DIN 551 and GB 73, ensuring interchangeability across global suppliers.
   • Rigorous Testing & Inspection: Each batch undergoes dimensional checks, drive-slot engagement testing, and corrosion evaluation (48 h salt-spray per ISO 9227) to guarantee performance consistency.
   • Full Traceability & Documentation: Material batch and heat-treatment records maintained from melt to finish; RoHS-compliant and free from magnetic anomalies, offering dependable service life in demanding environments.
