Midwest Fasteners Multi-Size Steel Woodruff Keystock Assortment

Midwest Fasteners Multi-Size Steel Woodruff Keystock Assortment

The Midwest Fasteners Multi-Size Steel Woodruff Keystock Assortment is a family of steel Woodruff keys used to lock pulleys, gears, sprockets and couplings onto shafts in small engines, pumps, automotive accessories and general machinery. Each key is steel keystock with the standard semicircular Woodruff profile, available across a broad range of wire sizes and product sizes from #1 through #E — including #1, #2, #3, #4, #5, #6, #8, #9, #10, #11, #13, #15, #18, #21, #91, #126, #152, #316, #726, #A, #B, #C, #D and #E — so a shop can match the correct keyway to a given shaft diameter without stocking a dozen separate part numbers. Select the specific wire size or product size needed for your repair or new-build keying job.
