DIN913 Internal Hex Socket Set Grub Screw Flat Point Alloy Steel carbon steel Grub Bolt Headless Screw

1. Performance & Material Properties
   • Alloy & Carbon Steel Construction: Made from quenched-and-tempered alloy steel (e.g., 4140 grade) or high-carbon steel (e.g., C1045), providing tensile strengths up to 800 MPa and hardness levels of 40–45 HRC.
   • Flat-Point Tip Design: Precision-ground flat end distributes clamping load evenly, minimizing substrate marring and delivering consistent holding power under both static and dynamic loads.
   • Surface Treatment Options: Available with zinc plating (8–12 µm) or black-oxide coating to guard against corrosion and galling in industrial or outdoor environments.
2. Detailed Application Range
   • Shaft & Collar Locking: Secures collars, gears, pulleys, couplings and sprockets on motor, gearbox and conveyor shafts without creating deep indentations.
   • Precision Machinery & Instrumentation: Holds linear guides, slides, bearing blocks, optical mounts and circuit-board standoffs in robotics, lab equipment and test fixtures.
   • Automotive & Heavy Equipment: Fastens components in braking systems, transmission housings, steering linkages and suspension assemblies.
   • General Industrial & Automation: Ideal for machine tools, actuators, fixture plates, jigs, dies and conveyor assemblies in manufacturing lines.
3. Effortless Installation & Adjustment
   • Internal Hex Drive: Recessed Allen socket (sizes 1.5 mm–8 mm) ensures slip-free engagement, precise torque control (up to 15 Nm) and minimal cam-out.
   • Self-Seating Flat Point: Cuts its own mating surface for a secure fit—no washers, thread-lockers or inserts needed—simplifying assembly and reducing part count.
   • Easy Removal & Repositioning: Flat-point tip can be reset or removed with standard hex keys without damaging adjacent components, cutting maintenance time.
4. Superior Quality & Long-Term Reliability
   • Tight Tolerances & Certification: Produced in ISO 9001–certified facilities to DIN 916 tolerances (±0.1 mm), ensuring interchangeability and precise fit.
   • Rigorous Testing: Each batch undergoes dimensional inspection, drive-torque consistency checks and corrosion resistance testing (240 h salt-spray per ASTM B117 for plated parts).
   • Full Traceability & Compliance: Material lot tracking from melt to finished part; RoHS-compliant and free of magnetic anomalies, guaranteeing dependable performance in demanding applications.
