Allied Threaded Metals specializes in manufacturing niche fasteners to meet specific requirements. experience and capability to produce non-standard fasteners, including screws; bolts (including extend, cut, safety wire holes, and cotter pin holes); studs; nuts (oversize tapping, jam nuts, slotted nuts, spherical face); couplings; spacers; standoffs; and many other custom fasteners and parts. Each part can be milled or manually machined to ensure the part exactly meets the specifications and requirements of the application and customer.

Of course, rather than manufacturing custom fasteners and parts from specific metal alloys, Allied Threaded Metals also has the capability of modifying standard parts. Allied focuses on modifying, resizing, and reshaping a variety of nuts, including hex, square, and round nuts. As part of the fastener modification process, Allied can supply the standard fasteners to which the modifications can be made, or the customer can provide the off-the-shelf products for alteration. Either way, the modifications will be made to meet the exact specifications of the application and customer.

What is Nut Tapping?

Generally, tapping is the process of cutting a matching set of threads into a piece of metal, plastic, acrylic, or wood. The process of tapping uses two separate tools: the tap which cuts the threads on the inner diameter of the hole, and the die which cuts the threads on the outer diameter of the bolt or screw. The process of cutting the threads using a tap is called tapping, and the process of using a die is called threading.

Nut tapping, then, is a process used to machine internal threads and screws on the inner sides of parts with holes. It can be done to meet various specifications for custom hardware. As a specialty fastener manufacturer, Allied Threaded Metals specializes in tapping oversized nuts for use in any application. As with custom part manufacturing, Allied can accommodate nut tapping to meet exacting requirements and standards.

There are a few main types of taps:

  • Plug Taps (or Second Taps) – As the most commonly used taps, they are easiest to line up and start your threads. They have a gentle taper, typically featuring three to five threads.
  • Bottoming Taps – This type of nut tapping cuts all the way down into a blind hole (a hole that doesn’t go clear through the material) and has threads to the bottom surface.
  • Tapered Taps – Similar to plug taps but with a more pronounced taper.
  • Powered Taps – A type of tap used in a lathe, a mill, or a drill press. These powered taps, commonly called a “spiral point” tap, are usually used in holes that go all the way through your working material.
  • Forming Tap – Pushes the material back into itself to form the threads. This method is generally only used in softer materials like mild steel, brass, and aluminum.

When it comes to nut tapping, Allied Threaded specializes in tapping oversized nuts and is capable of tapping nuts between ¼” to 4” in diameter. They tap and modify hex, square, and round nuts which can then be coated for corrosion protection. Allied taps more than one million nuts per year.
