Description

The Zipp Air Tool USA 192913 Air Hammer Retainer Spring is a heavy-duty, quick-change accessory designed to secure 0.401-inch shank chisels, punches, and rivet sets onto standard pneumatic air hammers and riveting guns. Engineered from high-tensile heat-treated spring steel, it provides maximum tension and fatigue resistance, preventing accidental tool ejection during intense, high-BPM reciprocating cycles.

Designed with universal threading for quick barrel installation, the 192913 retainer allows technicians and metal fabricators to swap out cutting bits, smoothing snaps, and flush sets rapidly by hand. Its resilient coil geometry absorbs lateral vibration and tool rebound, ensuring concentric bit alignment and consistent safety in collision repair, aerospace maintenance, and structural steel assembly.
