When selecting a hand riveter, prioritize the material of the body and jaws. Look for high-strength aluminum alloy or forged steel bodies for durability. The jaws should ideally be made of Chrome Molybdenum (Cr-Mo) steel, which offers superior hardness and wear resistance compared to standard carbon steel. Ensure the tool supports multiple nozzle sizes (typically 2.4mm, 3.2mm, 4.0mm, and 4.8mm) to handle various rivet diameters. Additionally, check for an ergonomic handle design with PVC or TPR grips to reduce hand fatigue during repetitive industrial tasks.
