Description

Hex nuts are required for most fastening purposes and are built for easy installation. While hex nut design seems to be simple, it is designed to deliver high-end efficiency and performance. Hex nuts are six-sided, internally threaded fasteners, mated with bolts, studs, screws and other externally threaded items. The inclusion of the hex nut ensures that the bolt, etc., remains in place.
