Re: jackplate installment
That bit about stainless nyloks binding ...<br /><br />Binding is often not the fault of nyloks - it occurs when a stainless nut is overtightened onto a stainless bolt, whether the bolt is a nylok or not. It's the stainless that's at fault, not the nylok itself.<br /><br />Tech term is 'galling' - often called cold welding. When s/s bolts and nuts are overtightened, the oxide film breaks down under excess pressure between the bolt and nut threads,and ‘cold welding’ takes place. This causes thread <br />seizure or even thread stripping. It is an assembly rather than a materials deficiency problem.<br /><br />Examine the threads of both bolt and nut. Bolt threads are generally smoother, because they are <br />rolled. Internal (nut) threads are rougher, because they are cut with a tap. If the nut thread appears unusually rough, use another nut. Avoid using bolts with damaged threads.<br /><br />As Lark2004 says, lubricate. Use a grease that contains moly (molybdenum disulphide) or graphite.<br />Or use bolt and nut of different grades of stainless, as above.<br /><br />Ciao
