Description

Industrial standoff components designed for precise spacing and secure mounting in automation, enclosure, and machinery applications. This product delivers a robust, metric-threaded male-female standoff with hex drive for reliable installation in dense assemblies.

Specs

  • Dimensions: Length 21 millimeters; Hex drive 6 millimeters
  • Finish: Plain
  • Drive type: Hex drive
  • Material: Aluminum
  • Thread type: M3-.05

Features

  • Integrated spacing: 21 millimeters overall length with 6 millimeter hex drive enables precise mounting and alignment in confined enclosures.
  • Torque and rotation control: Hex drive permits tool engagement with standard Allen keys; minimizes cam-out and up to torque loss in high-vibration environments.
  • Material properties: Aluminum body delivers favorable strength-to-weight ratio and adequate corrosion resistance for typical industrial settings; plain finish supports clean, uncoated interfaces.
  • Use cases: Enclosures, equipment racks, machine frames, automation assemblies, control panels, robotics platforms, and instrument housings.
  • Installation considerations: Ensure mating components accept M3 threaded hardware; verify target spacing equals desired standoff height; apply appropriate thread lubricant to enhance durability and ease of assembly.
