Acorn and cap nuts: Acorn nuts and cap nuts combine the hexagonal wrenching surface of standard nuts with a dome, the acorn or cap [which] is used to cover external threads that would be otherwise exposed. Standardized acorn nuts can be divided into two categories: low crown and high crown. The main difference between the two is the amount of available thread engagement . Low crown cap nuts can accept an external thread equal to the nominal diameter. High crown cap nuts have the capacity for 25% more thread engagement.
