Nib tap 1: 7/8”-9 O/S 6FL AH THD’D SHK NIB 2 Threaded shan 6 flutes 18 thread lead

7/8”-9 O/S 6FL AH THD’D SHK NIB

This tool is used to make fasteners (Nuts). Specifically, the 7/8-9 AH tap is tapping industrial steel hex nuts at a rate of 10,000/hour. It is held tight to a thread shank by a coupler and floats in a tapping machine.

This tool only spins in one direction and the fasteners load up on the shank and fall off the end as another fastener is tapped on to it.

The reason for the tap, coupler and shank is so the person using the tap only needs to replace the tap when it is worn out rather the entire assembly

On smaller sizes this assembly is one piece and labeled as a bent shank tap.

How are fasteners tapped?

The process of tapping small fasteners on an automatic tapping machine begins with properly loading the fasteners into the machine. Once the fasteners are loaded, the machine can be set to the desired tapping speed and size. The tap is engaged and the fastener is tapped as the machine rotates it in place.

A high speed nut tapping machine quickly and precisely taps a threaded hole in metal components. It is typically used in manufacturing processes to create internal threads in a workpiece. The machine can be powered by a variety of sources, such as electric motors, compressed air, or hydraulics. It is capable of reaching speeds of up to 10,000 rpm, making it an efficient way to produce a high volume of parts with high accuracy and repeatability.

Types of Fasteners

Fasteners are one of the most essential products of every manufacturing industry. In this article, we will discuss different types of fasteners, modern fastener tapping machines, and tooling methods. Fasteners are mainly used for creating the non-permanent joint between two or more mechanical parts whereas some of them are also used for permanent joining.

Fasteners are classified into different types according to their specific applications. Some of the main types of fasteners are:

  • Nuts and Bolts
  • Screws
  • Washers
  • Rivets
  • Anchors
  • Retaining rings
  • Inserts
  • Clevis and Cotter pins

Bent shank taps are used to create threads in blind holes and are designed to break off when the thread is complete, leaving a clean thread that does not require further finishing. It is so named because the shank of the tap has a slight bend (usually 15 to 20 degrees) making it easier to control and reduce the risk of the tap being pulled out of the hole while cutting.

What are High Speed Nut Taps?

Nut taps are generally used by nut manufacturers for production tapping on nut tapping machines. Their long small diameter shanks permit the tapped nuts to accumulate on the shank without reversing the tap. These taps are provided with long chamfers to distribute the cutting action efficiently for this type of operation.

What are couplings? 

Couplings are mechanical devices used to connect two shafts together at their ends for the purpose of transmitting power. They are used to protect against overload, compensate for misalignment, isolate vibration and absorb shock. Couplings can be rigid, flexible or a combination of both, depending on the requirements of the application

Fastener Materials 

Around 90% of fasteners are produced by Steel. Tap selection should be carried out in accordance with the nature of the material, nature of the operation, and operating conditions. We have special taps for all of the below materials commonly used for fasteners:

  • Carbon steel
  • Stainless steel
  • Aluminum
  • Titanium
  • Brass and bronze
  • Non-metallic
