LOW HEAD SOCKET CAP SCREWS

Low head socket cap screws are designed for applications where standard socket head cap screws are too tall, yet reliable clamping strength, precision alignment, and repeatable performance are still required. With a reduced cylindrical head height, these fasteners enable secure assembly in shallow counterbores and space‑constrained designs without sacrificing structural integrity.

Low head socket cap screws are commonly used in compact machinery, tooling, automation systems, electronics housings, robotics, and precision mechanical assemblies where vertical clearance is limited.

COMMON APPLICATIONS

  • Compact machinery and automation equipment.
  • Tooling, fixtures, and precision alignment systems.
  • Electronics housings and enclosures.
  • Robotics and motion control assemblies.
  • Medical, aerospace, and instrumentation components.

DESIGN CONSIDERATIONS

Because of the reduced head height, wrench engagement is more limited than with standard socket head cap screws. Proper tool fit, controlled torque application, and correct material selection are essential. Low head designs are best suited for applications requiring moderate to high strength with restricted head clearance rather than maximum torque capacity.
