Spring washers create more frictions and resistance between head of fastener and substrate when exert a force .
Spring washers are left hand direction but allow the threads can be tightened in a right hand direction . the higher edge will bites into the underside of the fastener when a left hand turning is applied , so spring washers are ineffective on left hand , Spring washer must to be placed after a flat washer when both washers make a conjunction role .
