Why Choose These Cap Screws

Designed for durability and corrosion resistance, zinc plating protects against wear in light-to-moderate environments. The compact button head sits flush or slightly recessed to maintain a clean appearance while offering secure clamping in electronics, automotive, furniture, and general mechanical applications.

Applications

  • Electronics enclosures and control panels
  • Automotive components and dashboards

Choose a matching 4-40 thread nut or tapped hole when assembling components. Use an appropriately sized Allen key to tighten the socket drive until the desired clamping force is achieved.
