Creating threads on a metal or plastic surface is a common need in many mechanical applications. One of the most popular methods of creating threads is by using taps and dies. In this guide, we will explore how to use taps and dies to create threads.

If using a tap, reverse the tap and turn it counterclockwise to remove it from the material. If using a die, reverse the die and turn it counterclockwise to remove it from the rod or bolt.

If using a tap, secure the material in a vise or clamp. If using a die, insert the rod or bolt into the die and secure the die in a vise or clamp.

Taps and dies come in a variety of sizes and types, depending on the size and type of thread you need to create. It is important to choose the correct size and type of tap or die for your specific application.

This paper reviews the processing, properties, and structure of carbon fibers. Carbon fibers are derived from several precursors, with polyacrylonitrile being the predominant precursor used today. Carbon fibers have high strength (3–7 GPa), high modulus (200–500 GPa), compressive strength (1–3 GPa), shear modulus (10–15 GPa), and low density (1.75–2.00 g/cm3). Carbon fibers made from pitch can have modulus, thermal, and electrical conductivities as high as 900 GPa, 1,000 W/mK, and 106 S/m, respectively. These fibers have become a dominant material in the aerospace industry and their use in the automotive and other industries is growing as their cost continues to come down.

Round die: This die is used for creating external threads on rods and bolts. It is often used in combination with a die handle or holder.

Taps and dies are tools used to cut threads into metal and plastic surfaces. Taps are used to create internal threads (such as those found on nuts and bolts), while dies are used to create external threads (such as those found on screws and bolts).

Choose the correct tap or die size and type. This will depend on the material you are working with and the size and type of thread you need to create.

If using a tap, apply cutting oil to the tap and start the thread by turning the tap clockwise. If using a die, apply cutting oil to the rod or bolt and start the thread by turning the die clockwise.

Hex dies: This die is used for creating external threads on hexagonal bolts and is often used in combination with a die handle or holder.

Taper tap: This tap has a more gradual thread starting point and is ideal for starting threads or for use in softer materials. The taper tap can also be used for through holes, as it helps guide the tap through the material.

Bottoming tap: This tap has a much shorter taper than the other two types and is ideal for use in blind holes, where it is important to ensure the full depth of the hole is threaded.
