slotted headless set screws

KEY CHARACTERISTICS

• Headless, flush installation suitable for compact or moving assemblies.

• Single-slot drive compatible with universal flat-blade screwdrivers.

• Lower torque capacity than socket-drive screws; ideal for delicate components.

• Easy to adjust in the field and suited for legacy or consumer-grade hardware.

POINT STYLES (AVAILABLE FROM G‑FAST)

• Cup Point – general purpose holding.

• Flat Point – non-marring; ideal for adjustments.

• Cone Point – penetrates softer surfaces for locking.

• Oval Point – gentle friction-based holding.

• Dog Point (Half or Full) – indexing into holes or grooves.

HEADLESS SLOTTED SET SCREWS

Slotted set screws are headless, fully threaded fasteners tightened with a single-slot (flat) screwdriver blade. They are used in applications where torque requirements are low, adjustments are frequent, cost matters, or only basic tools are available. While not as strong as socket-drive set screws, they remain valuable for light-duty positioning, holding, and calibration tasks across many industries.

COMMON APPLICATIONS

  • Precision adjustment mechanisms (optical, metrology, scientific instruments).
  • Electrical devices, switchgear, connector clamps, and terminals.
  • Consumer and legacy mechanical products.
  • Low-load collars, knobs, sliding or rotating components.

WHY G‑FAST DISTRIBUTION

Slotted set screws are essential for adjustment mechanisms, electrical hardware, consumer products, and legacy equipment where simplicity and accessibility matter more than clamping force. G‑Fast supplies a complete range of slotted set screw styles and materials, ensuring customers can source both modern and legacy fastening solutions. Through Fasteneering™, we review application requirements to recommend the appropriate drive style, material, and point geometry.

ADVANTAGES

  • Universal tool compatibility for field service.
  • Reduced risk of over-tightening delicate components.
  • Cost-effective manufacturing and procurement.
  • Well-suited for frequent adjustments and fine positioning.
  • Fully threaded, headless design keeps assemblies compact.

LIMITATIONS

  • Lower torque transmission and easier to strip under heavy load.
  • Poor vibration resistance without threadlocker.
  • Prone to cam-out with improper screwdriver fit.
  • Not suitable for critical mechanical retention or high clamping loads.
