What the set contains

This Westward tap and die set provides 16 fractional pieces for cutting and repairing UNC threads. Seven hand taps and matching round fixed dies cover the thread sizes listed in the specifications. The dies are made from high speed steel for durability in general workshop use.

Who this suits

Mechanics and maintenance teams who need a compact fractional kit for occasional thread repair on UNC fasteners will find the range practical. Buyers who require metric threads, larger diameters or a wider selection of pitch options should look at a different kit.

Behaviour under sustained load

High speed steel dies resist wear during repeated hand threading operations. The round fixed design keeps alignment steady when cutting multiple holes in sequence. Heat buildup remains low with proper lubrication and moderate feed pressure.

Questions about this item

What tap wrench and die stock do I need to turn the 1/2 In.-13 through 7/16 In.-14 hand taps and round fixed dies in this set?

The set uses ANSI-standard tap shanks, so choose a tap wrench that fits the 1/4 In. to 1/2 In. range and a die stock sized for the matching round fixed dies.

Can the UNC thread taps and dies cut new threads in mild steel that already has worn or damaged UNC threads of the same pitch?

Yes, the high-speed-steel taps and dies follow the UNC standard, so they will chase or recut 1/4 In.-20, 5/16 In.-18, 3/8 In.-16, 7/16 In.-14, 1/2 In.-13, 5/8 In.-11 and 3/4 In.-10 threads in compatible material.

How do I verify a freshly cut 3/8 In.-16 thread matches the set's UNC specification?

Check the thread with a 3/8 In.-16 UNC thread gauge; the go gauge should pass freely and the no-go gauge should stop within three turns.
