Keyways are used for additional torque transmission capabilities and to prevent slippage on the shaft. BulletPoint2 : Two-piece styles have opposing hardware for a balanced design. BulletPoint3 : Proprietary Nypatch anti-vibration hardware prevents galling, maintains high holding power, and allows for multiple screw insertions. Nypatch significantly reduces installation time as no additional screw treatment is needed prior to use. BulletPoint4 : Made from 303 stainless steel with hardware of like material for high corrosion resistance. Machined to a fine burr free finish. BulletPoint5 : Hardware exceeds ANSI standards for maximum torque capabilities.
