Irwin 24605 Tap Die Set 6-32 to 1/4-20 Unc Unf 12 Pc

Product Description

The IRWIN 24605 is a 12-piece tap and die set covering thread sizes from 6-32 up to 1/4-20 in both UNC and UNF thread standards. Taps and dies are machined from carbon steel with a bright finish for corrosion resistance and visual inspection ease. The set includes hex-shaped dies, a plain die stock, and a T-handle tap wrench, making it a self-contained threading solution. It is suited for cutting and chasing threads on fasteners, fittings, and threaded rod in field repair and shop maintenance work. Licensed tradespeople and skilled maintenance technicians are the primary users.

This set is appropriate for light-to-medium threading tasks in mechanical, electrical, and plumbing maintenance applications where standard UNC and UNF fastener threads are involved. The included size range addresses the most common small-fastener thread sizes encountered in HVAC equipment panels, electrical enclosures, and plumbing fixture hardware. The die stock and T-handle tap wrench allow immediate use without additional tooling.

Installation Notes

Tap and die work should be performed by a qualified technician familiar with thread-cutting technique. Apply appropriate cutting fluid to extend tool life and produce clean threads. When tapping blind holes, back the tap out periodically to clear chips and prevent breakage. Inspect threads after cutting to confirm proper fit before assembly.
