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 Hillman 5/16-18 in. Zinc-Plated Steel SAE Keps Lock Nut — a dependable fastener designed to keep assemblies tight in the face of vibration and dynamic loads. Built for reliability, this single nut delivers locking performance in a compact, boxed package for easy on-hand use.

Why this Hillman Keps Lock Nut stands out

  • Locking performance that lasts — the Keps locking design resists loosening under vibration, helping assemblies stay secure without constant re-tightening.
  • Corrosion resistance — zinc-plated steel provides durable protection against rust in both indoor and light outdoor environments.
  • Standard compatibility — coarse 5/16-18 threads match common SAE bolts, making it a versatile choice for a wide range of projects.
  • Quality materials — Grade 2, made from sturdy steel, delivering dependable strength for everyday fastening tasks.
  • Convenient packaging — boxed packaging with 1 nut per package simplifies storage and quick replacement in tool boxes or workbenches.

Ideal for

  • DIY enthusiasts and homeowners completing furniture assembly, shelving, or repair projects where movement occurs.
  • Light- to medium-duty machinery, automotive maintenance, and equipment mounting that benefits from a locked connection.
  • Shop technicians and contractors who value ready-to-use, single-piece components for faster job turns.

How it helps you get it right

When you’re assembling components that experience vibration, a traditional nut can loosen over time. The Hillman Keps Lock Nut provides a reliable locking action that minimizes back-off, reducing downtime and the need for retorque. The zinc finish keeps the fastener looking and performing well in environments where moisture or humidity might otherwise corrode uncoated steel.

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.
