1/2-13 H3 Tap Set for Internal Threading
This three-piece hand tap set cuts 1/2-13 UNC internal threads in a single pass. High-speed steel construction suits general-purpose threading in steel, aluminium and plastic. The H3 limit provides a standard fit for through-hole and blind-hole work. Right-hand thread direction matches common fastener requirements.
Check Thread Size and Hole Preparation Before Use
Verify the workpiece requires 1/2-13 UNC threads and that the drilled hole matches the correct tap drill diameter. Ensure the material is compatible with high-speed steel cutting tools. Confirm you have a suitable tap wrench or holder for the 3 3/8 in overall length. The set contains three taps so no additional pieces are included.
Bright HSS Finish and Four-Flute Design
The uncoated bright finish reduces friction during hand tapping and allows easy visual inspection of cutting edges. Four flutes provide balanced chip evacuation and smoother thread surfaces in ductile materials. Thread length of 1 21/32 in supports deeper holes while the shorter overall length improves control. Package quantity of three gives a complete starter, plug and bottoming progression.

Questions about this item
What comes in the Westward Hand Tap Set package and do I need to buy a tap wrench separately?
The package contains three HSS fractional taps sized 1/2-13 UNC with H3 limits. A tap wrench or handle is not included and must be purchased separately.
Should I choose the H3 limit or a different limit for a standard 1/2-13 UNC thread?
H3 is the standard limit for general-purpose 1/2-13 UNC threads and suits most through-hole and blind-hole tapping jobs in steel or aluminium.
How does the 1 21/32 in thread length and 3 3/8 in overall length affect reach in a deep hole?
The 1 21/32 in thread length cuts full threads to that depth, while the 3 3/8 in overall length lets the tap reach through thick plates or fixtures without bottoming out.
