Description

Industrial standoffs and spacers designed for precision alignment in electronics housings and automated assemblies. This specification sheet presents dimensional data, material characteristics, and functional use cases for high-reliability engineering applications.

Specs

  • Dimensions: Body length 1-3/8 inch
  • Drive type: Hex
  • Configuration: Hex male-female
  • Material: Aluminum
  • Thread type: 4/40

Features

  • Material: Aluminum alloy delivers high strength-to-weight ratio with natural corrosion resistance, suitable for electronics housings and lightweight mechanical assemblies.
  • Corrosion resistance: Natural oxide layer on aluminum provides reliable performance in typical industrial environments.
  • Configuration: Hex male-female profile enables tool engagement from both ends for secure fastening and consistent spacing during assembly and field maintenance.
  • Dimensional stability: Precisely machined 1-3/8 inch body length maintains repeatable spacing across assemblies, reducing variance in panel-to-panel and PCB-to-housing spacings.
  • Applications: Suitable for electronics enclosures, PCB mounting, and lightweight robotic systems requiring repeatable spacers and clean, compact mounting geometry.
  • Packaging: 250 pieces per package, supporting batch fabrication and supply-chain planning for automation lines.
