Description

Industrial fasteners and spacers designed for precision mounting in control panels, enclosures, and machinery. This brass standoff combines hex drive geometry with female threaded ends to deliver reliable spacing and alignment in high-volume assemblies.

Specs

  • Dimensions: Hex size 1/4 inch; Length 1-1/2 inch
  • Finish: Plain
  • Drive type: External hex
  • Material grade: Brass
  • Thread type: #4-40
  • Package quantity: 250 per package

Features

  • Functional benefits: Provides precise spacing between mating components with female threaded ends, enabling clean, repeatable assembly in panel and enclosure applications.
  • Use cases: Ideal for electronics enclosures, control panels, sensor arrays, and machinery frames requiring rigid mounting and consistent alignment.
  • Material advantages: Brass offers good machinability and moderate corrosion resistance in typical industrial environments; plain finish preserves conductivity where appropriate and allows natural patina development.
  • Thread compatibility: Designed for #4-40 machine screws to secure components with consistent torque and repeatable clamping force.
  • Drive availability: Hex head enables tool-assisted installation with standard wrenches, supporting repeatable assembly in manual and automated processes.
  • Electrical considerations: Brass is conductive; when isolation is required in electrical assemblies, pair with non-conductive spacers or insulators to prevent shorting.
