M39 (57mm Internal Height) Thread Protection Nut Cap | Black LDPE

For black finishing caps on M39 fasteners, this M39 push-fit thread protector combines a tidy appearance with protective coverage over nut and thread areas.

Used as a finishing and protection cap, it can improve assembly presentation while helping prevent thread damage before future maintenance work. This makes it useful for finishing ordinary nut assemblies without the added depth of a telescopic cap.

Common Applications

  • Providing tidy thread protection on workshop fabrications and jigs
  • Reducing contact with protruding threads on handrails and safety barriers
  • Capping threaded studs on bridge railings and guardrail systems
  • Protecting threads on HVAC supports, roof plant and external services
