Buying Guide

Match tap size and thread form

Select taps that correspond to the hole diameter and thread pitch you need—metric (e.g., M20, M24) and UNF sizes require different tap geometries and labeling

Prefer HSS material for general metalwork

High-speed steel (HSS) taps resist wear and handle manual through-hole tapping in steel, aluminum, and most common alloys without specialized coatings

Choose plug taps for through-hole threads

Plug taps (commonly listed as ‘plug’ or 2–3 flute designs) are a balanced choice for through holes because they start easily and cut enough full threads through the part

Consider flute count for chip control

Four-flute or spiral designs can improve chip evacuation in softer materials and deeper holes, while standard 2–3 flute plugs work well for general through-hole tapping

Check user ratings and single-piece options

Customer ratings and availability of single-piece taps let you evaluate real-world performance for the exact size you need without buying full sets
