Minerallac 70720J – Frequently Asked Questions

1) What bolt size do Minerallac fender washers fit?
They're drilled for 1/4 inch fasteners, so any standard 1/4-20 bolt, screw, or threaded rod anchor passes through. Outside diameter is what you choose: a 1 inch OD (part 70720J) or a 2 inch OD (part 40733J). Same hole, different bearing surface.
2) Should I use the 1 inch or the 2 inch fender washer?
It comes down to how soft the material under the washer is. The 2 inch OD (40733J) spreads the clamp load over roughly four times the area of the 1 inch, so it's the one for thin sheet metal, drywall, fiberglass, or an oversized or torn-out hole you're trying to bridge. The 1 inch OD (70720J) is enough when the substrate is solid and you just want more bearing than a flat washer gives. Both take a 1/4 inch fastener.
3) Can I use a fender washer instead of a flat washer for mounting electrical panels and boxes?
That's one of the stated uses. A fender washer is a flat washer with a much larger outside diameter for the same hole size, so it's used where a standard washer would pull through or dent the material: panel and equipment mounting, sheet metal, HVAC component fastening, plumbing, and industrial assembly. It is not a lock washer and provides no vibration resistance on its own.
4) What is the exact part number for the 2 inch Minerallac fender washer?
The 2 inch outside diameter version is Minerallac 40733J. The 1 inch is 70720J. Both are 1/4 inch bore, so when you order, the size option is the OD, not the hole.
5) Where are Minerallac fender washers made?
Country of origin is Taiwan. Worth knowing up front if you're buying against a spec or a procurement policy that requires origin documentation on fasteners.
