Alloy Steel Socket Set Screw Internal Hex Drive Cup Point Allen Grub Screw Carbon Steel

description

1. Performance & Material Properties
   • Alloy & Carbon Steel Options: Manufactured from quenched-and-tempered alloy steel (e.g., 4140 grade) with tensile strength up to ≈800 MPa and hardness 40–45 HRC, or from high-carbon steel (e.g., C1045) offering tensile strength ≈600 MPa and hardness 28–35 HRC.
   • Surface Treatments: Zinc-plated (8–12 µm) or black-oxide coated to provide basic corrosion resistance and reduce galling.
   • Precision Machining: Cup-point tips and internal hex bores are CNC-milled to tight tolerances, ensuring consistent thread engagement and clamping force.
2. Detailed Application Range
   • Motion-Control Assemblies: Secure collars, gears, pulleys and couplings on drive shafts in motors, gearboxes and conveyor systems.
   • Industrial Machinery: Lock components in machine-tool spindles, linear actuator assemblies, bearing housings and heavy equipment linkages.
   • Automotive & Transportation: Fasten brake calipers, transmission housings, steering columns and suspension linkages.
   • Robotics & Automation: Position linear guides, slides, end-effector fixtures and sensor mounts with high precision and vibration resistance.
3. Effortless Installation & Adjustment
   • Internal Hex Drive: Available in Allen key sizes from 1.5 mm to 8 mm, providing slip-free torque delivery (up to 15 Nm) and minimizing cam-out.
   • Cup-Point Tip: The concave point bites into mating surfaces to resist loosening under vibration, yet allows easy repositioning or removal with standard hex keys.
   • Self-Seating Design: Cuts its own mating surface without need for washers, thread-lockers or inserts—reducing part count and assembly time.
4. Superior Quality & Long-Term Reliability
   • Tight Tolerances & Certification: Produced in ISO 9001-certified facilities to different standards tolerances (±0.1 mm), ensuring interchangeability and precise fit.
   • Rigorous Testing: Each batch undergoes dimensional inspection, drive-torque consistency checks and corrosion testing (240 h salt-spray per ASTM B117 for zinc-plated, ISO 9227 for black oxide).
   • Full Traceability & Compliance: Material traceability from melt to finished part, RoHS-compliant and free of magnetic anomalies—guaranteeing consistent, dependable performance in demanding environments.
