Blackburn 14040FW-C – Frequently Asked Questions
1) What is the Blackburn 14040FW-C flat washer made of, and will it hold up outdoors on a grounding connection?
It is a silicon bronze flat washer. Silicon bronze is the standard material for direct burial and exterior grounding hardware because it resists corrosion and it galvanically matches the bronze and copper connectors and lugs it is normally stacked with, so you avoid dissimilar-metal problems at the joint.
2) What bolt size does the Blackburn 14040FW-C washer go with?
It is sized for 1/4 inch hardware, which is how Blackburn designates it. Use it under the nut or bolt head on 1/4 inch grounding bolts, connector studs, and bonding hardware.
3) How thick is the Blackburn 1/4 inch silicon bronze flat washer, and does it add much stack height?
Thickness is 0.26 inch (6.6 mm). That is a heavy section for a 1/4 inch washer, so count it when you are checking remaining thread engagement on a short bolt or a shallow connector stud. On a stack of two washers it adds better than half an inch.
4) What diameter does the Blackburn 14040FW-C washer cover on the mating surface?
Blackburn lists an inside diameter of 11/16 inch on the 14040FW-C. Check that against the hole or slot you are bearing across, since a washer only spreads load if it overlaps solid material on both sides of the opening.
5) Should I use a silicon bronze washer or a plain steel one on a ground rod clamp?
Go bronze. A zinc plated or plain steel washer sitting against bronze or copper grounding hardware in a wet or buried location sets up a dissimilar-metal cell and the steel corrodes first, loosening the connection. The Blackburn 14040FW-C is silicon bronze, which is the same family as the connector it bears on.
6) Is the Blackburn 14040FW-C sold individually or only in a box?
The selling unit is each, so you can buy a single washer or order the exact count a job needs rather than a full bag. Part number to specify is 14040FW-C.
