In-Store Exclusive

This one's worth the trip to the store.

Brands like Weber, Milwaukee, Yeti, and DeWalt restrict where their products can be sold online — and for good reason. In-store buyers get authentic products, full manufacturer warranty, and access to pricing that simply isn't allowed to be advertised on the web.

  • Authorized dealer network · Full manufacturer warranty & support
  • Guaranteed authentic · No counterfeits, no gray-market resellers
  • The brands set these standards · Be wary of sellers who don't follow them

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

When you need to create clean, durable internal threads in metal, the Milwaukee High Carbon Steel SAE Straight Plug Tap 1/4-28 NF is built to perform with reliability you can feel in your hands. Crafted from high carbon steel and finished in black oxide, this tap stands up to repeated use in metalworking projects and maintains sharpness longer than budget alternatives.

Key advantages

  • Premium material: High carbon steel for exceptional wear resistance and edge retention in tough metals.
  • Precision alignment: Straight plug tap design delivers stable cutting and straight, accurate threads.
  • Corrosion resistance: Black oxide finish reduces friction and helps extend service life in demanding environments.
  • Compact, practical size: 2.5 in overall length suits standard through-holes and common metalworking scenarios.
  • Shop-friendly packaging: Clamshell packaging keeps the tool organized and ready for quick grab-and-go use.
  • Single-piece utility: Includes 1 tap (drill bit not included) so you can pair it with your preferred pilot tool and setup.

Ideal uses and who benefits

This plug tap is purpose-built for cutting 1/4-28 NF internal threads in metal parts, from automotive repair to machine shop fabrication and DIY metal projects. It’s especially valuable for restoring damaged threads, creating new threaded entries in housings, brackets, and covers, or completing fastener assemblies where precision fits matter. Ideal for professionals and serious hobbyists who want dependable, long-lasting performance from their tapping tools.

How to use

  1. Secure the tap in a tap wrench or T-handle for steady, controlled cutting.
  2. Prepare a proper pilot hole for 1/4-28 NF (use a standard threading chart to confirm the size).
  3. Lubricate the cutting edge with a suitable tapping oil or light machine oil to reduce friction and heat buildup.
  4. Turn the tap slowly clockwise, applying even pressure. Periodically back off to break and clear chips.
  5. Continue until the threads reach the desired depth, then remove the tap and inspect the finished threads for smooth operation.

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.
