Using tension instead of friction, Hasco America’s zinc-coated wedge lock washers Z693 reliably secure screw connections and eliminate the bolt-loosening effect when exposed to vibrations or heavy loads.

The reusable, two-part washers, bonded in pairs, guarantee a positive lock of the screw even at low torque. Maximum service temperature is 200°C. Washers also enable reliable functioning, including with lubricant usage. Hasco’s standard mold units is supplemented by eleven different sizes for common screw diameters.
