Cleveland 54272 #8-32 Straight Flute Hand Tap

Cleveland #8-32 Straight Flute Hand Tap

This Cleveland 54272 tap cuts internal UNC threads for #8-32 fasteners in through-hole or blind-hole applications. The high-speed steel construction with bright finish suits general-purpose threading in steel, aluminium and plastic. A four-flute design provides chip clearance and cutting stability for hand or powered tapping operations. Thread limit H2 and class of fit 3B deliver standard tolerance for everyday assembly work.

Capacity and headroom for #8-32 threads

The 3/4 in thread length and 2 1/8 in overall length accommodate typical material thicknesses and fixture depths. A 75 percent thread drill size of 3.40 mm prepares holes for full thread engagement without excessive torque. Right-hand thread direction matches the vast majority of standard hardware. The tap handles production of clean, accurate threads in a single pass when the hole is correctly sized.

Upgrade from worn or undersized taps

Replaces dull, chipped or incorrectly sized taps that produce loose or oversized threads. The H2 limit restores proper class 3B fit when previous tooling has drifted out of tolerance. Worth the change when thread gauges show rejection rates rising or when a new batch of #8-32 hardware must be installed to specification. Not for metric threads, left-hand threads or thread sizes other than #8-32 UNC.
