Hard Lock Nut【1-200 Pieces Per Package】
SUNCO
[Shape] Upper nut (convex type) and lower nut (concave type) are available.
· The top nut is perfectly circular with respect to the bolt, but the bottom nut has been eccentrically machined off-center with respect to the bolt.
[Features] Since the lower nut is eccentric, tightening the upper nut will apply a lateral force due to the wedging action. Friction to this male thread prevents loosening.
· Can be manually tightened to your desired position.
· Can be used repeatedly.
