The distinctive blue color of these chuck drivers is your assurance that they can withstand the kind of impact driver stress characteristic for each fastening application. And all Malco Impact-Grade power drivers are precisely machined for positive, fail-proof engagement of the fastener head. These Magnetic Hex Driver selections feature a spring-loaded, floating magnet that prevents breakage resulting from impact driver stress or higher profile hex head fasteners that may seat directly on the magnet.
