For hexagonal screws and nuts
The hexagonal screw is clamped in the socket wrench insert by two spring balls and a permanently elastic, highly resistant shrink sleeve. A front steel band provides effective protection against mechanical injuries. This is particularly useful in narrow workspaces where a second hand cannot be used to hold the screw.
The hand and machine nuts (ISO 2725 part 3) allow the insert to be used for manual and machine operation. The user needs only one nut assortment for almost all applications.
