NO – We do not recommend that anything be welded to the screw. The material that the screw is made of is a high strength alloy that is not considered weldable. You may be able to get something to stick to the screw but there will be little if any strength and it could break off suddenly and cause injury. The handle that is provided with each mechanical tool is of the correct length to provide the most torque while staying within the tool’s design limits. Using an extension or “cheater bar” can over stress the tool and cause permanent damage.
