Description

Industrial-grade standoffs designed for panel mounting and equipment assemblies in demanding environments. Nylon female-female spacers provide consistent clearance, non-conductive separation, and reliable mechanical support across industrial installations.

Specs

  • Dimensions: Across Flats 5/16 inch; Length 1/2 inch
  • Thread type: #4-40
  • Material: Nylon

Features

  • Electrical isolation: Dielectric properties of nylon prevent undesired conduction between mounted components, improving safety and reducing signaling interference in control panels.
  • Chemical resistance: Nylon exhibits compatibility with common industrial solvents and lubricants, extending service life in harsh manufacturing environments.
  • Vibration damping: Polymer body provides modest damping of transmitted vibrations, helping maintain alignment and reduce wear on fastened assemblies.
  • Wear mitigation: Non-metallic construction minimizes galling and marring when assembling with softer metals, preserving mating surfaces.
  • Installation use cases: Ideal for mounting electronic enclosures, machine panels, relay blocks, and instrumentation housings where non-conductive spacers are required.
