Left-Hand Threaded Super-Corrosion-Resistant316 Stainless Steel Thin Hex Nuts. With threads that tighten to the left and made of 316 stainless steel, these nuts won’t loosen from counterclockwise motion in saltwater and corrosive environments. They’re half the height of standard hex nuts, so they fit where there’s low clearance.

The Westfield Fasteners range of UNF Nuts is presented below. These are designed to be used in conjunction with the equivalent sized UNF bolts, screws and washers. Care must be taken
