SOCKET HEAD CAP SCREWS (SHCS)

Socket Head Cap Screws (SHCS) are high-strength fasteners designed for demanding industrial assemblies requiring superior tensile capacity, precise fit, and dependable clamping performance. Their cylindrical head and internal hex drive support high torque transmission and efficient installation in compact or recessed locations.

Engineered with controlled head geometry, socket depth, shank-to-thread transition, and bearing surface dimensions, SHCS deliver exceptional strength-to-size performance. They are widely used in machinery, automation, tooling, robotics, heavy equipment, transportation assemblies, and any environment requiring consistent, high‑integrity fastening.

ENGINEERING & PERFORMANCE CHARACTERISTICS

  • Manufactured to industry‑standard tolerances for dimensional accuracy.
  • High tensile strength and shear capacity across inch and metric ranges.
  • Available in coarse, fine, and ISO thread series.
  • Chamfered or flat points for controlled assembly.

COMMON APPLICATIONS

  • Industrial machinery and automation systems
  • Tooling, fixtures, and precision assemblies
  • Robotics and motion systems
  • Agricultural, construction, and industrial equipment
  • Power generation and heavy mechanical systems
  • Aerospace, automotive, and engineered transportation assemblies
