these go on standard 3/8 inch bolts, right? just want to make sure before i order a bunch

sized for 3/8 inch fasteners. The flat design spreads load evenly across the surface, so you get good contact without concentrating stress on any one spot. Works well anywhere you need to protect a surface or keep a fastener from pulling through.
