Description

The Recknagel 6-48 Tap (00056-0648) is an industry-standard tool optimized for the tough, heat-treated steels found in modern firearm receivers. While Recknagel is a German manufacturer, they produce this tap specifically to service the 6-48 Unified Special (UNS) thread—the most common size for mounting optics on rifles from Remington, Winchester, Savage, and others.

Crafted from premium High-Speed Steel (HSS), this tap offers superior durability and heat resistance compared to standard carbon steel alternatives. Its precision-ground flutes ensure efficient chip removal and a smooth finish, which is critical to preventing tool breakage or thread galling in expensive receivers. It is typically used as a “plug” or “bottoming” style tap to allow for maximum thread depth in shallow blind holes.
