The super-strong H20 series offers a compact, lightweight, aerospace quality all-metal locking nut. The 220,000 psi strength rating is higher than 180,000 psi NAS1804 nuts and considerably higher than 160,000 psi MS21042 Jetnuts.

These self-locking nuts have a reduced-size 12-point head for easy wrench access. The all-metal construction allows their use up to 450° F. The top portion of the nut is deformed to an oval shape during manufacture to produce the self-locking action. Cad plated alloy steel construction, sometimes with an optional dry moly lubricant coating (manufacturer's option; sorry, no choice on our end). Sold individually.
