Malco produces sheet metal hand tools for construction, HVAC installation, and metal fabrication. Shop a selection of aviation snips and stud crimpers for cutting and fastening light-gauge metal framing. Malco aviation snips feature hardened steel blades and compound-action handles that multiply hand leverage for controlled cuts in sheet metal and other materials. Stud crimpers are used to secure metal studs and track together without screws, helping speed up steel framing installation.
