Every order helps keep your local hardware store on the corner.

Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Introducing the Anvil 1-1/2 in. FPT Galvanized Malleable Iron Lock Nut — a purpose-built solution for secure, vibration-resistant threaded connections. Designed for 1-1/2" female pipe thread (FPT) fittings, this lock nut combines rugged strength with reliable corrosion resistance to keep assemblies tight in plumbing and industrial applications.

Why this lock nut stands out

  • 1-1/2" FPT thread size ensures compatibility with standard female pipe thread connections for quick, accurate installations.
  • Malleable iron construction delivers durable strength and improved resilience against impact and periodic movement compared with other materials.
  • Galvanized finish provides robust rust and corrosion protection, ideal for damp environments, outdoor setups, and long-term service.
  • Lock nut design engineered to resist loosening from vibration and thermal cycling, helping maintain a secure seal over time.
  • Versatile plumbing and piping hardware suitable for residential, commercial, and light industrial projects where dependable threaded connections are critical.

Ideal use cases

  • Secure connections in drain assemblies, water lines, and other 1-1/2" FPT piping configurations.
  • Applications in areas prone to vibration or movement, where a locking mechanism preserves alignment and seal.
  • DIY repairs or professional installations requiring a durable, corrosion-resistant locking nut in moist environments.

Installation tips

  • Confirm compatibility: ensure the mating fittings use 1-1/2" female pipe threads (FPT).
  • Prepare threads: clean the threads and apply an appropriate thread sealant or PTFE tape on male threads if required by the system.
  • Tighten with the correct tool to the recommended torque for your fittings, avoiding over-tightening which can damage threads or deform the lock nut.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
