Description

Industrial cap screws deliver flush mounting and high torque retention in compact assemblies. The flat head pin-in socket drive variant provides precise alignment and secure clamping in space constrained industrial applications.

Specs

  • Dimensions: Nominal diameter: #4; Length: 3/8 inch; Head style: Flat
  • Drive type: Socket (internal hex)
  • Material grade: Alloy steel
  • Thread type: 4-40

Features

  • Low-profile mounting: Flat head sits flush with the surface to maintain a clean exterior on enclosures, panels, and equipment housings where space is tight.
  • Pin-In alignment: Pin-in socket design provides precise initial alignment and helps prevent rotation during assembly and under dynamic loading.
  • Vibration resistance: Internal hex socket drive coupled with a flush head enhances clamping stability and reduces loosening in vibration-prone environments.
  • Torque control: Socket drive enables repeatable tightening with compatible hex drivers, supporting consistent clamping in precision assemblies.
  • Industrial applicability: Suitable for machinery frames, control panels, instrumentation housings, and compact electronics enclosures where performance and appearance matter.
