The winch lock bolt is a custom 3/8-16 precision security bolt made from 1045 carbon alloy steel heat treated to Grade 5 yield strength. The key patterned head bolt is proprietary and the matching key is not available at your local retail hardware store. The winch lock bolt cannot be removed with ordinary screw drivers, pliers, or commonly sold security bits.
