The holding function by a metal plate in the wrench reduces the risk to loose screws and nuts. This metal plate is exchangeable, secures screws and nuts with extra hard notches and reduces the slipping risk.
The integrated collar may avoid the screw from slipping downwards and allows to apply high rotation force.
The double hex-head geometry allows the form-fit contact with the screw or nut and consequently the reduction of slipping risk.
The back tork angle for only 30° avoids time taking readjustment of the wrench when screwing.
