Meet the Milwaukee High Carbon Steel SAE Straight Plug Tap 7/16-20 NF — a purpose-built threading tool designed to create precise, durable internal threads in metalworking projects. Built to meet demanding shop standards, this plug tap delivers dependable performance for automotive, fabrication, and maintenance tasks.
Why this plug tap stands out
-
Material and durability: High carbon steel offers solid rigidity and wear resistance, helping the tap hold its edge through repetitive cuts in steel, cast iron, and other machinable metals.
-
Black oxide finish: Reduces friction during threading and provides mild corrosion resistance, contributing to smoother operation and longer tool life in workshop conditions.
-
Straight plug design: Optimized for clean, consistent threads in through-holes, making it a reliable choice for standard internal threading tasks.
-
Exact size and spec: 7/16-20 NF threads, SAE standard, ensuring compatibility with common fasteners used in machinery and automotive applications.
-
Practical length: 3.25" overall length provides adequate reach while maintaining rigidity for precise tapping in confined spaces.
-
Convenient packaging: Carded, 1-piece packaging keeps the tap protected and easy to store in a shop or tool chest.
-
Package contents: Tap only — drill bit not included, so you can pair with your preferred drill and drill bit for the exact hole size you’re working with.
Ideal use cases
Use the Milwaukee 7/16-20 NF straight plug tap to cut or repair female threads in metal components such as engine blocks, brackets, housings, and machine frames. It’s well-suited for maintenance, repair, and fabrication projects where strong, accurately threaded holes are required for bolts or studs. If you’re upgrading a dormant or damaged threaded hole or assembling components that rely on a 7/16-20NF fastener, this tap helps you achieve reliable, load-bearing threads.
Best practices for optimal results
- Always pair the tap with the correct drill size for your 7/16-20 NF thread. Although a drill bit is not included, consult standard tapping charts to determine the proper pilot hole diameter for your material.
- Use cutting fluid or oil to minimize heat and friction, extend tap life, and produce smoother threads.
- Maintain a straight, steady pressure and back off slightly to break chips as you cut. Avoid forcing the tap, which can dull the edge or cause misalignment.
- After tapping, clean the thread area and chase threads if needed to ensure full engagement with fasteners.
Who benefits
This tap is an excellent fit for automotive hobbyists, machinists, and general fabricators who need reliable, repeatable internal threads in metal parts. If you want predictable performance, straightforward tooling, and a durable solution for frequent threading tasks, this Milwaukee plug tap is a solid choice.
