Sleeve Anchor Flange Self Lock Nut

Flange lock Nuts are one piece, all-metal prevailing torque hex flange nuts. Being all-metal, they are not subject to the temperature and chemical limitations of non-metallic (such as nylon) insert type lock nuts. The protruding circular flange increases the nut's bearing surface allowing them to be used with irregular and oversized holes. Commercial and industrial applications include lawn and garden equipment and truck manufacturing. Flange lock nuts are also called:  flange style automation Lock Nut, prevailing torque flange nuts, deformed thread flange lock nuts.  They are often used with 150 ksi hex flange bolts. Lock washers are not used with prevailing torque lock nuts.
