     This product completely prevents hex bolts from co-rotating. It is available in M12 to M72 sizes and patent pending. It does not use jagged knurled surface irregularities to generate friction, instead it has a special structure that changes the equivalent friction diameter to ensure that the bolts do not co-rotate. Eliminating the use of tools which prevent bolt rotation, and reducing the number of workers required from two to one, which can significantly reduce the time required to tighten bolts. Strength level: 8.8 ; Material: S45C ; Surface treatment: trivalent chromate.
