Briggs & Stratton 9X53MA Shoulder Bolt 3/8-16 x 0.565 OEM Replacement Part

The Briggs & Stratton 9X53MA is a genuine OEM shoulder bolt designed to exact factory specifications for use in Briggs & Stratton powered lawn and garden equipment. This shoulder bolt measures 3/8-16 thread x 0.565" shoulder length, providing a precise, secure fit in applications where component alignment and controlled clamping depth are critical.

Using the correct OEM part ensures proper fit without modification and helps prevent premature wear on mating components.
