JW Winco, Inc., A Ganter Company, now has available EN 5320 Plastic Torque Limiting Wing Nuts. 

These wing nuts are used when the manually applied torque is to be limited. “When turned clockwise, the torque of the wing nut triggers an ‘over-engagement’ when the specified torque is reached. When tightening, this will ensure the maximum permissible torque is not exceeded,” said John Winkler, CEO, office of the president at JW Winco. “When turned counter-clockwise, the torque needed for loosening will always be transmitted properly.”

The technopolymer plastic is glass fiber reinforced and temperature resistant up to 176°F (80°C). The wing nuts are available in either a black matte or orange matte finish.
