M42 x 137mm Black Self Threading Nut Cap (51mm Max Nut Height) | LDPE

Manufactured for substantial threaded rod and bolt ends, this M42 bolt thread cap screws into position to create a secure protective cover. It is suited to M42 bolt thread cap searches where the key requirement is thread protection with a secure black cap finish.

Its black LDPE construction offers a tidy finish on heavy duty assemblies while helping to prevent impact damage to exposed threads. The cap is especially useful where fastener ends remain accessible after installation. This SKU is designed for standard nut height coverage where a lower 51mm clearance is preferred over a taller lock nut cap. The self forming thread cap wording suits maintenance teams looking for a reliable cover for exposed threaded ends. As a large nut cap, it helps protect large fastening points during installation, storage and long-term use.

Common Applications

  • Construction steelwork
  • Site-installed threaded rods
  • Temporary works hardware
  • Large frame assemblies
