View model pageGeneral guidance
In general, an Allen head bolt is a threaded fastener driven by a hex key inserted into a recessed socket in its head, which allows a flush or low-profile fit. The unified coarse (UNC) thread designation describes the thread standard, and the size shown in the name should be checked against the catalog record.
Order using part number 0309621 exactly as listed. Because this part appears in the catalog within feeder drive shaft group assemblies, check that the recorded model and serial conditions for those parent assemblies match your machine before ordering.
