What Are Hand Taps
Hand taps are cutting tools used to create internal screw threads (female threads) in holes. They are manually turned using a tap wrench or handle rather than in a machine. Hand taps cut threads into pre-drilled holes so that bolts or screws can be properly fitted. Because hand taps are worked manually, they provide control, flexibility and precision, especially in jobs where machine tapping isn’t feasible or safe.
Why Are Hand Taps Used?
- Versatility: Hand taps allow for threading in hard-to-reach or awkward positions where machines cannot reach.
- Control & Accuracy: They allow for slower, more careful cuts, which can reduce risk of misalignment or damage to the thread.
- Cost-Effective for Small Runs: When you're not doing mass-production, hand taps are more economical: no large machinery needed, less setup.
- Repair & Maintenance: Ideal for tapping, retapping or cleaning up existing thread holes.
- Variety of Materials: From steel to aluminium, plastic, or cast iron—hand taps can be used on a wide range of materials with the correct tap.
What Type of Hand Taps are Available?
- Complete Sets:Kits that include first, second and bottom (or taper, plug etc.) taps – useful for full threading operations or for versatility.
- First (or Taper) Tap:Called the “starter” tap: has a pronounced taper so it gradually cuts the thread, useful for starting the hole or when aligning is difficult.
- Second (or Intermediate) Tap:Less taper, deeper cut than first tap; follows the first to deepen and refine the thread.
- Bottom (or Plug) Tap:Cuts thread all the way to the bottom of a blind hole; has very little taper so you can reach full thread depth.
What Thread Forms are Hand Taps Available in?
Hand taps are available in a variety of thread forms to suit different standards and applications. Some of the common thread forms include:
- Metric threads(e.g. Coarse & Fine series)
- Whitworth threads(e.g. BSW/BSP)
- Unified threads(e.g. UNC/UNF/UNEF)
- Whitworth British Standard Pipe(e.g. BSP/BSPT)
- Acme / Trapezoidal(e.g. for power screws / linear motion)
- Buttress Threads
- NPT / Tapered Pipe Threads
- Special Threads(custom or non-standard) depending on the toolmaker)
