M18 x 86mm Telescopic Thread Protection Nut and Washer Cap DIN 125 | 36.9mm OD | Black LDPE

This M18 bolt thread cap is produced from black LDPE and sized for a 27mm nut across flats, making it useful for taller fixings where the thread needs a protected enclosure.

The telescopic form is designed around long projections, so the cap gives coverage without forcing the installer to cut or alter the protruding thread. The 36.9mm outside diameter gives clear washer coverage while the 86mm height allows space for the protruding thread.

What Are Telescopic Thread Protection Nut and Washer Caps?

A telescopic thread protection cap is used when the fixing needs more internal height than a standard nut cap. This M18 option is designed to cover the nut and washer area while helping reduce corrosion, dirt build-up and sharp exposed threads.

Common Applications

  • Finishing fencing and perimeter security bolts
  • Protecting exposed threads on gate hardware
  • Covering washer areas on boundary installations
  • Reducing snagging on publicly accessible fixings
