Three-piece HSS TiN hand tap set cuts #5-44 UNF threads in taper, plug and bottoming styles

  • HSS construction resists wear during repeated threading
  • TiN coating reduces friction for smoother cutting
  • UNF #5-44 fine pitch suits precision fastening
  • Three-piece set covers taper, plug and bottoming taps
  • Right-hand threads match standard fastener orientation

Threading set for fine-pitch holes

This three-piece set from CHICAGO-LATROBE provides taper, plug and bottoming hand taps for cutting #5-44 UNF threads. The high-speed steel cutters suit maintenance and light production work where a right-hand internal thread is required.

#5-44 UNF thread size and H2 limit

The taps are ground to a #5-44 UNF pitch with an H2 thread limit for a class 2B fit. Select this set only when the drawing or specification calls for this exact diameter, pitch and tolerance combination.

TiN coating extends edge life under repetition

A titanium nitride surface treatment reduces friction and wear during repeated hand-tapping cycles. The coating helps maintain cutting geometry longer than uncoated HSS when threading multiple holes in steel or non-ferrous metals.

Questions about this item

What does the #5-44 UNF thread size mean when I use these taps in a real job?

The #5-44 UNF size indicates a fine-pitch thread with 44 threads per inch, designed for precise fastening in thin materials where a standard coarse thread would strip.

How does the H2 thread limit affect the fit of the threads I cut?

The H2 limit produces a class 2B fit, giving a standard allowance for assembly while keeping the thread within tolerance for general-purpose use.

What physical dimensions do I need to clear for the 1 15/16 in overall length?

Each tap measures 1 15/16 in long with a 5/8 in thread length, so allow at least that depth plus handle clearance in your work area.
