Minerallac 40715J – Frequently Asked Questions
1) What bolt size do Minerallac 40715J fender washers fit?
The hole is 3/16 inch, so these take a 3/16 inch bolt or screw shank, or a #10 screw which is slightly under that. Outside diameter is 1-1/4 inch, giving a bearing surface roughly six and a half times the hole area, which is the point of a fender washer: spreading clamp load so the head does not pull through thin material.
2) Will a 3/16 x 1-1/4 fender washer keep screws from pulling through sheet metal or drywall?
That is the job it is built for. With a 1-1/4 inch outside diameter against a 3/16 inch hole, the load spreads over a wide ring instead of concentrating at the fastener head, which is why these get used in auto body panels, sheet metal assembly, and electrical equipment mounting. The washer is steel at 0.047 to 0.080 inch thick, so it resists cupping under torque rather than dishing into the panel.
3) Are Minerallac zinc plated fender washers okay for damp or outdoor use?
Zinc plated steel handles general damp indoor and sheltered conditions and resists surface rust far better than bare steel. It is a sacrificial coating, not stainless, so for continuous outdoor exposure, coastal air, or wet process areas, stainless steel is the better call. For panel mounting, HVAC work, and interior construction the zinc plating is what most jobs spec.
4) What is the difference between a fender washer and a standard flat washer this size?
Hole size is the same idea, outside diameter is not. A standard 3/16 flat washer has an OD a little over twice the bore; this one runs out to 1-1/4 inch. You pick the fender washer when the material under it is thin, oversized, slotted, or already damaged, and you need the clamp load spread. Where the substrate is solid metal or the bolt seats in a machined counterbore, a standard flat washer is the correct part and the wide one just gets in the way.
5) How thick are these fender washers, and does the thickness vary?
Thickness is specified as a range, 0.047 to 0.080 inch, which is normal for stamped commercial fender washers rather than a defect. If you are stacking washers into a tight grip length or shimming to a set dimension, measure the ones in hand instead of working from a single nominal number.
