Product overview
Machine threading matched to the job.
High-speed steel machine taps are selected against the machine type, spindle and alignment, workpiece material, hole form, thread depth, chip movement, lubrication and required production cycle.
A machine tap is not selected by size alone. Confirm the thread standard, tolerance, geometry, coating, dimensions and process conditions in the quotation.

Practical thread reference
Know the thread.
Specify it clearly.
For HSS taps and dies, metric pitch is measured in millimetres; inch threads are usually specified in TPI (threads per inch).
| Thread name | Full name / meaning | Example size |
|---|---|---|
| M – Metric Coarse | ISO metric coarse thread | M10 × 1.5 mm |
| Metric Fine / MF | ISO metric fine thread; normally marked M with pitch | M10 × 1.0 mm |
| UNC | Unified National Coarse | 1/2″–13 UNC |
| UNF | Unified National Fine | 1/2″–20 UNF |
| UNEF | Unified National Extra Fine | 1/2″–28 UNEF |
| UN | Unified constant-pitch series, such as 8-UN, 12-UN and 16-UN | 1-1/2″–8 UN |
| UNS | Unified National Special | 1/2″–24 UNS |
| UNR | Unified thread with a rounded external root | Specify size, TPI and series |
| UNJ / UNJC / UNJF / UNJS | Unified J-profile threads, including coarse, fine and special series | Specify complete drawing designation |
| BSW | British Standard Whitworth, coarse | 1/2″–12 BSW |
| BSF | British Standard Fine | 1/2″–16 BSF |
| BSPP / G | British Standard Pipe Parallel | G 1/2 |
| BSPT / R | British Standard Pipe Taper; R denotes external taper | R 1/2 |
| Rc / Rp | BSP mating internal threads: Rc taper, Rp parallel | Rc 1/2 or Rp 1/2 |
| NPT | National Pipe Taper | 1/2″–14 NPT |
| NPTF | Dryseal National Pipe Taper | 1/2″–14 NPTF |
| NPSM / NPSL / NPSC | American straight pipe-thread series for different applications | Specify exact series |
| BA | British Association thread | 0 BA, 2 BA, 4 BA |
| BSB | British Standard Brass thread | Diameter × TPI BSB |
| BSC / CEI | British Standard Cycle / Cycle Engineers’ Institute | Diameter × TPI BSC |
| ACME | Inch trapezoidal thread, 29° profile | Diameter × TPI ACME |
| Stub ACME | Shallower ACME thread | Diameter × TPI Stub ACME |
| Tr | Metric trapezoidal thread, 30° profile | Tr20 × 4 |
| Buttress | Asymmetric thread for heavy axial loads | Specify standard and profile |
| Rd | Round thread | Specify standard, diameter and pitch |
How to read an order size
- M10 × 1.5: 10 mm nominal diameter, 1.5 mm pitch.
- 1/2″–13 UNC: 1/2 inch nominal diameter, 13 TPI, UNC thread.
- Pitch in mm = 25.4 ÷ TPI.
- RH / LH: right-hand / left-hand thread.
- Pipe sizes are nominal: a 1/2″ BSP or NPT thread does not have a 12.7 mm outside diameter.
Unified thread families are covered by ASME B1.1. This practical industry list includes common metric, Unified, British and pipe series; it is not every specialist thread standard worldwide.
