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

Meet the Milwaukee High Carbon Steel SAE Straight Plug Tap in 5/16-18 NC—a purpose-built tool crafted for metalworking where precise internal threads are non-negotiable. Built to endure demanding shop conditions, this tap is your go-to for reliable, repeatable threading in steel and other tough metals.

Construction and finish you can trust: the tap is made from hardened high-carbon steel, delivering enduring edge life and consistent performance through countless projects. The straight plug design keeps the cutting action stable in through-holes, promoting straight, true threads and reducing the risk of cross-threading in busy workspaces.

The finish matters: a black oxide coating protects the cutting edge, minimizes glare in bright shop environments, and provides a modest layer of corrosion resistance to help extend tool life between sharpenings and replacements.

Key details at a glance:

  • Thread size: 5/16-18 NC (National Course)
  • Length: 2.5 inches
  • Material: High carbon steel
  • Style: Straight plug tap
  • Packaging: 1 piece in clamshell packaging
  • Drill Bit Included: No

Who will benefit: this tap is ideal for professional machinists, fabricators, technicians, and DIY enthusiasts who routinely create or repair internal threads in metal components—think engine brackets, brackets and mounts, and other structural parts where accuracy and durability drive performance.

Why it matters in practice: accurate 5/16-18 NC threads ensure fasteners seat properly, resisting loosening under vibration and load. The Milwaukee straight plug tap delivers clean, consistent thread profiles, reducing rework and helping you complete assemblies with confidence.

Practical usage tips: pair this plug tap with a stable tap wrench and appropriate cutting fluid to minimize heat and prolong life. Keep the tool aligned as you begin, apply steady, even pressure, and advance with short, controlled turns, backing off periodically to clear chips. Ensure you’re tapping a compatible hole size for 5/16-18 NC to achieve the best results in steel and other metals.

With Milwaukee behind it, this tap isn’t just a tool—it’s a reliable companion for dependable threads and smoother fabrication workflows. If you’re tackling metal projects that demand precise, durable internal threads without frequent tool replacement, this 5/16-18 NC straight plug tap is built to meet and exceed those expectations.

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.
