Blackburn 31230 – Frequently Asked Questions
1) Is the 31230 wing screw bronze, and can it be used in a direct burial or damp grounding location?
Bronze is the material. Bronze is the standard body material for grounding clamps used on water pipe and ground rods precisely because it resists corrosion in damp and buried conditions and is galvanically compatible with copper conductors. Pair it with a bronze clamp body rather than mixing it onto a steel or aluminum connector.
2) What is the 7/8 inch spacing on the Blackburn 31230?
The 31230 wing screw carries a 7/8 inch spacing dimension. Use that figure to check it against the clamp you are servicing: if the screw travel or hole spacing on your clamp body does not match 7/8 inch, this is not the right replacement screw for it.
3) What is the Blackburn 31230 wing screw used for?
The Blackburn 31230 is a bronze wing screw used as a replacement or service part on ground clamps, the mechanical connector type used to bond grounding conductors to pipe, rod or other electrodes. It tightens by hand or with a wrench rather than needing a driver, which is why it shows up on clamps installed in tight meter bases and crawl spaces.
4) Does the Blackburn 31230 come as a single screw or in a bag?
It is sold each, one wing screw per unit, under manufacturer part number 31230. Electricians restocking a van or a maintenance crib ordering spares for a run of ground clamps should order the quantity they need rather than expecting a multi-pack.
5) Is the Blackburn 31230 made in the USA?
Country of origin is the United States. That matters on federally funded and government MRO work where domestic-source documentation is part of the submittal package.
