The WILLIAMS COMFORT PRODUCTS 13571 is a replacement knurl nut designed for use with the 8-inch pipe wrench. This small but critical hardware component secures the adjustable jaw assembly on the wrench, allowing the tool to function correctly and maintain proper jaw tension during pipe work. It is a direct OEM-style replacement part intended for technicians and tradespeople who need to restore a worn or damaged pipe wrench to working condition rather than replace the entire tool. At 0.035 pounds, it is a lightweight single-piece fastener sold individually.
This knurl nut is intended for use during routine tool maintenance in plumbing, HVAC, and general mechanical service environments. When the original knurl nut strips, cracks, or becomes difficult to turn, replacing it restores smooth jaw adjustment on the wrench. It is appropriate for professional shop use and field service kits where maintaining functional hand tools is part of standard practice.
Designed as an OEM-style replacement knurl nut for the WILLIAMS COMFORT PRODUCTS 8-inch pipe wrench.
Installation of this replacement knurl nut is a basic hand-tool maintenance task typically performed by any qualified tradesperson. No power tools are required. Thread the knurl nut onto the adjustable jaw stem by hand, ensuring the threads engage cleanly before tightening. Inspect the jaw and heel components for wear before reinstalling to confirm full wrench function is restored.
