M39 x 131mm Telescopic Thread Protection Nut and Washer Cap DIN 125 | 78.6mm OD | Black LDPE

Engineered for extended stud protection, this M39 telescopic bolt cap helps shield the washer, nut and protruding thread from impact, grime and weather exposure.

The cap helps prevent thread contamination, which can make future maintenance easier when fasteners need to be removed or retightened. The 6.0mm washer thickness detail should be checked against the assembly before ordering for the most secure fit.

What Are Telescopic Thread Protection Nut and Washer Caps?

This style of bolt projection cap is designed to snap over the hex nut and washer after tightening. The clamping edge sits beneath the nut chamfer while the ribbed interior helps hold the cap securely in place.

Common Applications

  • Protecting threaded rods used with hex nuts
  • Covering washer and nut combinations on brackets
  • Finishing exposed long stud connections
  • Supporting safer handling around fastener ends
