M20 (39mm Internal Height) Thread Protection Nut Cap | Black LDPE

Where a compact cover is needed over a M20 nut, this M20 black nut cap for exposed threads uses a 39mm internal height and 40.4mm outside diameter to suit low-profile protection work.

This cap is well suited to repeat fitting work because it protects the fastener area without adhesives, special tooling or permanent changes to the assembly. The standard format is suited to applications where the thread does not project far beyond the nut face.

Common Applications

  • Covering bolt ends on road furniture, barriers and roadside equipment
  • Capping exposed studs on storage systems, racking and mezzanine fittings
  • Providing reusable protection for temporary works and site installations
  • Protecting nuts on marine hardware and waterside structures
