Buying Guide

Match thread standard and size

Confirm whether the repair is UNC, UNF or metric and choose a tap with the exact thread pitch and diameter to avoid further damage

Choose plug vs through taps

Use plug taps for partial-thread repairs and through taps for holes that go all the way through; both are available in high-speed steel suited for hand use

Prioritize material and coating

High-speed steel (HSS) taps resist wear during re-threading; consider coated variants only if recommended for the parent material

Check tap geometry for damaged threads

Taps with chamfered leading edges and standard hand-tapping geometry help engage damaged threads more smoothly when restoring threads

Consider single taps vs sets

Single-size taps let you buy the exact replacement (common for repair work) while sets offer multiple sizes for broader shop use and convenience
