A $500,000 crushing machine able to be loaded with gravel, rock and construction aggregate has an unreliable nylon type locknut. The locknut is used to fasten the large connecting cylinders with a pivot joint.
Due to the extreme impact vibration caused during operation, the nylon locknut would frequently loosen, resulting in constant shutdowns and equipment inspections. A safety risk, a $20,000 repair fee and several weeks of shutdown meant that a solution needed to be sought.


Using 2” Heavy Hex Security Locknuts, the cylinders are fastened with a superior fastening solution. The benefits are many: there have been no incidents involving the joint for the last 3 years, the product and manufactures reputation is improved, and reduced maintenance costs.
