Would an extra long nut be better than standard nuts for extra strength?
In theory yes but in practical terms no. Standard length nuts as offered in the catalog provide the best price/ performance ratio. Extra long nuts require special tooling and gauging to work properly. They often experience fit up problems, creating hot spots that can expand thermally under load and bind locally on the screw. If capacity is a concern, then larger diameters should be considered. Where special over-length nuts are required or where larger than standard nuts are used for mounting convenience, users should consider adapting standard nuts by boring out the worn threads to fit the exterior of the standard nut (see Figure 12 in the Taps section). Contact Roton Engineering before designing a special nut which is longer than twice the major diameter of the screw.
