Blackburn 37200BB-C – Frequently Asked Questions
1) What size is the Blackburn 37200BB-C hex head bolt?
The Blackburn 37200BB-C is a 3/8-16 bolt: 3/8 inch diameter with 16 threads per inch, coarse UNC thread, and a 2 inch length under the head. It takes a standard 9/16 inch wrench socket for a 3/8 inch hex head. Mating hardware needs to be 3/8-16 as well, so a 3/8-16 silicon bronze nut and matching washers if you are keeping the whole connection bronze.
2) Why use a silicon bronze bolt instead of galvanized or stainless for a ground connection?
Silicon bronze is what the 37200BB-C is made from, and it is the standard material for grounding and bonding hardware because it is compatible with the bronze and copper bodies of ground clamps, connectors and ground rod couplings. Bolting steel or zinc-plated hardware to a copper or bronze connector sets up a dissimilar-metal couple that corrodes in buried or wet locations. Keeping the bolt bronze keeps the whole connection the same family of metals.
3) Is the Blackburn 37200BB-C sold individually or in a box?
It is sold each, so one bolt per unit ordered. If you are assembling multiple connections, count the bolts you need and order that quantity. Nuts and washers are separate items.
4) Will a 2 inch long 3/8-16 bronze bolt be long enough for my clamp or busbar connection?
The 37200BB-C gives you 2 inches of shank under the hex head. Add up your stack: clamp body or busbar thickness, any lugs or cable terminals, flat and lock washers, and leave enough thread for the nut to fully engage. Two inches covers a typical ground bar plus a couple of lug pads; a deep clamp saddle or a thick stack of terminals may need a longer bolt.
5) What head does the Blackburn 37200BB-C have, and can it be driven with a socket?
Hexagonal head, so it drives with an open end wrench, box wrench, or a socket, which matters in a ground vault or on a busbar where there is no room to swing a screwdriver. There is no drive recess in the top of the head.
