Key features

  • Cap Screws Button Socket head design for a clean, compact appearance that sits flush with surfaces.

The combination of a button socket head, fine thread, and black oxide finish makes them ideal for applications where appearance matters as much as performance.

Why choose these cap screws

  • Low-profile button socket head reduces snag risk and provides a clean surface look.
  • Precision fine thread connection enhances engagement in thin materials and improves clamp force control.
  • Durable alloy construction offers reliable strength with manageable weight.
  • Corrosion resistance from the thermal black oxide finish extends service life in challenging environments.

Installation tip: Ensure compatibility with 1/4-28 threaded components and use appropriate torque settings to achieve optimal clamping without damaging the material. For best results, pair with compatible threaded inserts or nut plates designed for fine-thread cap screws.
