Westward #10-24 H3 Hand Tap Set
This three-piece set provides H3-limit UNC taps for cutting #10-24 right-hand threads in general-purpose materials. Each tap is made from high-speed steel with a bright, uncoated finish and four flutes for chip clearance. The 7/8 inch thread length and 2 3/8 inch overall length suit standard through-hole and blind-hole work. Supplied as a matched trio for consistent fit.
H3 limit capacity and headroom
The H3 limit creates a standard class-of-fit for #10-24 threads, delivering reliable engagement in mild steel, aluminium and plastics. Four flutes give adequate chip room for the 7/8 inch cutting depth, but deep blind holes may need frequent withdrawal to prevent packing. High-speed steel handles moderate heat, yet sustained high-speed production runs will dull the edges faster than coated alternatives.
UNC thread standard practical limits
Unified National Coarse #10-24 defines the pitch and major diameter, so these taps cannot cut fine-pitch or metric threads. Right-hand orientation restricts use to conventional fastener direction. The bright finish offers no lubricity enhancement, requiring cutting fluid to avoid galling in stainless or tough alloys. Package quantity is fixed at three taps per set.

Questions about this item
Will the #10-24 UNC threads cut cleanly into mild steel plate I already have drilled?
Yes, the high-speed steel taps with four flutes and H3 limit are designed for standard UNC threads in common materials including mild steel.
How do I confirm each tap is cutting true #10-24 threads after I start the hole?
Check thread engagement with a matching #10-24 UNC bolt; it should start smoothly and reach full depth without binding.
Does the three-piece set include a taper, plug and bottoming tap so I need nothing else?
The package contains three taps of the same #10-24 H3 specification; separate tap wrenches or handles must be supplied by the user.
