Description

The Recknagel US 1/4″-22 Tap Set (00056-1422) is a premium workshop tool designed for applications where standard thread pitches do not provide sufficient engagement or strength. The 1/4″-22 size is a “Unified Special” (UNS) thread often found in specialized tactical mounting systems and custom bolt-action receivers that require more robust anchoring than the smaller 6-48 or 8-40 standards.

By providing this as a 2-piece set, Recknagel ensures a safer and more precise threading process in hard receiver steels:

Taper/Roughing Tap: Starts the thread and aligns the tool.

Finishing Tap: Cuts the thread to its final depth and profile for a perfect fit with 1/4″-22 screws.

Manufactured from High-Speed Steel (HSS), these taps offer exceptional wear resistance and the ability to cut through toughened alloys without losing their edge. This set is essential for armorers performing custom rail installations or repairing specialized American-pattern large-bore mounts.
