M18 x 49mm Telescopic Thread Protection Nut and Washer Cap DIN 125 | 36.9mm OD | Black LDPE

Developed for long bolt projection coverage, this M18 LDPE cap helps conceal sharp thread ends and gives the fixing a more controlled external finish.

The washer coverage helps protect the bearing area around the fixing rather than just the nut itself. This is useful on exposed brackets, support plates and assemblies where the washer face is visible. With lock nut suitability marked as No, it can be considered for taller or more varied fastening stacks.

What Are Telescopic Thread Protection Nut and Washer Caps?

Black LDPE nut caps provide a protective cover for exposed fasteners without changing the fixing underneath. This telescopic version is especially suited to taller studs where thread ends need to remain covered.

Common Applications

  • Protecting HVAC support frame fixings
  • Covering nuts and washers on rooftop equipment
  • Reducing thread exposure on plant supports
  • Improving finish on external service brackets
