Acorn & Cap Nuts:
Acorn nuts and cap nuts combine the hexagonal wrenching surface of standard nuts with a dome, the acorn or cap, 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.
