M16 Liquid Tight Threaded Plug | Black Nylon

Offering a clean finish for threaded apertures, this M16 plug combines a black Nylon body with practical hex-head installation. This makes it a practical waterproof threaded plug for UK industrial sealing work.

The hexagonal head gives engineers a positive wrenching surface for controlled installation, while the screwdriver slot helps with adjustment in tighter panel areas. The black finish is often preferred for darker housings, machinery frames and discreet enclosure builds.

Common Applications

  • Production line equipment upgrades
  • Closing spare metric threaded holes in control panels
  • Industrial sensor port blanking
  • Outdoor equipment covers
