Hitachi Knob - 302-458
Original Hitachi part 302458 — replacement spindle/adjustment knob for Hitachi circular saws. This molded plastic knob matches the original form and mounting for the saw’s spindle/angle clamp and installs in the same location as the factory part.
Designed to mate with the saw’s M6 knob bolt (the knob assembly uses an M6×37 knob bolt in the same parts, so it secures to the existing spindle/bolt hardware without modification.
Fits (Models from Hitachi/HiKOKI parts lists) C6BU / C7U / C7BU / C9U and similar Hitachi/HiKOKI cutters. Use it as a direct replacement when the original knob is cracked, stripped, or missing to restore proper adjustment and safe operation.
