Inquiry (采购产品): caster axles 1 diam. Can I use 1" grade 8 bolts for your steel wheel W-630-FST-? Are your Bolt-And-Nut type axles a special bolts? What I am concerned about is the fit between the bolt OD and the bearing ID of the inner race will a std. off the shelf bolt work? **** Hidden Message ***** John Maddock 63026 Company: Continental Manufacturing CO.
