In general, a locking bolt is a threaded fastener designed to resist loosening under vibration, which is common in heavy equipment and engine assemblies. Catalog descriptions such as a fractional thread size with a length in inches identify the fastener's standard form, but exact material, coating and installation requirements must be confirmed against the catalog.
Please order using part number 0302135 as listed in the catalog. Before ordering, check the serial number and parent-unit conditions recorded for the associated catalog occurrences, since those conditions are not confirmed for every machine configuration.
