A-B115X112MA-AI NUT.50-20 HEX FLG SER

One New Aftermarket Replacement 1/2-20 Hex Flange Serrated Nut for Murray / Fits Briggs & Fits Stratton Lawn and Snow Equipment

This 1/2-20 hex flange serrated nut (also referenced as Nut .50-20 Hex Flg Ser) is an aftermarket replacement for OEM part number 15X112MA used by Murray and Fits Briggs & Fits Stratton on snowblowers and lawn equipment. The integrated flange acts as a built-in washer to distribute clamping load over a wider bearing surface, while the serrated face bites into the mating part to resist loosening under vibration -- eliminating the need for a separate lock washer in most applications.
