Blackburn 37040FW-C – Frequently Asked Questions
1) Why use a silicon bronze washer instead of a galvanized or stainless one on a grounding connection?
Silicon bronze is the material the 37040FW-C is made from, and it is used in grounding and bonding work because it stays compatible with the copper conductors, bronze lugs and bronze ground clamps it sits against. Mixing dissimilar metals at a buried or damp connection invites galvanic corrosion and a rising resistance path; keeping the washer in the same bronze family avoids that.
2) How thick is the Blackburn 37040FW-C flat washer, and is it stout enough for direct burial ground connections?
Thickness is 0.064 inch. That is a standard flat washer section, not a heavy structural plate, so it does the job it is meant for: distributing bolt load across a lug or clamp face and protecting the seating surface. For grounding hardware buried or exposed to weather, the bronze material matters more than the section thickness.
3) Is the 37040FW-C sold in a box or individually?
It is sold each. One 37040FW-C washer per unit, so order the exact count your connections call for rather than a fixed carton quantity.
