Description

Industrial fastener components designed for precise panel spacing and reliable mounting. This specification sheet covers brass standoffs with nickel finish used across enclosure and equipment assemblies within harsh environments.

Specs

  • Dimensions: Hex size 5/16", Length 1/2"
  • Finish: Nickel finish
  • Thread type: #4-40 UNC
  • Material: Brass

Features

  • Corrosion resistance: Nickel finish over brass provides durable surface protection against moisture and chemical exposure commonly encountered in industrial enclosures and equipment mounting.
  • Thread compatibility: Internal #4-40 threads on both ends enable standard cap screws, supporting quick assembly and disassembly with minimal risk of thread galling.
  • Standoff geometry: Female–female configuration maintains precise separation between components, enabling controlled gasket compression, cable routing, and chassis alignment.
  • Material benefits: Brass core offers favorable machinability and non-magnetic characteristics; nickel plating increases wear resistance and reduces galling during repeated assembly cycles.
  • Use cases: Ideal for panel mounting in control cabinets, instrument housings, motor controllers, and industrial equipment enclosures where rigid alignment and clean aesthetics are required.
