Blackburn 25100BB-C – Frequently Asked Questions
1) What size is the Blackburn 25100BB-C hex bolt?
The Blackburn 25100BB-C is a 1/4 inch diameter hex head bolt with a 1 inch length. That combination is sized for hardware and connector work where a short bolt is clamping two thin bearing surfaces rather than passing through a thick assembly.
2) Why use a silicon bronze bolt instead of a plain steel or galvanized one on a grounding connection?
Silicon bronze is what the 25100BB-C is made of, and it is the standard choice for direct-burial and outdoor electrical bonding hardware because it stays compatible with the bronze and copper bodies of ground clamps and connectors. Bolting a copper alloy connector with plain steel invites galvanic corrosion at the joint, which is the thing that eventually loosens a ground connection. Steel and galvanized hex bolts are fine for general structural fastening, but for a copper-to-copper electrical path the bronze bolt is the matching material.
3) Does this Blackburn bolt come with a nut or washers?
The 25100BB-C is the hex bolt only, sold as a single piece. Silicon bronze nuts and washers, if your connection needs them, are separate line items, and you want them in the same bronze alloy so the whole joint stays one material.
4) What part number do I order for a 1/4 x 1 inch silicon bronze hex bolt from Blackburn?
The manufacturer part number is 25100BB-C. That is the Blackburn silicon bronze hex head bolt in 1/4 inch diameter by 1 inch length.
5) Can this bronze hex bolt be used outdoors or direct buried?
Silicon bronze holds up in wet and buried service, which is why it is the alloy used on grounding and bonding hardware that sits in soil, in a handhole, or on an exterior building steel connection. The 25100BB-C is a bronze bolt throughout, not a plated steel bolt, so there is no coating to wear through and expose a corroding base metal.
6) What head does the Blackburn 25100BB-C take, and what tool do I need?
Hexagonal head, so it drives with a standard wrench or socket rather than a screwdriver or hex key. On a bronze bolt, run it up with a wrench and stop at snug plus a turn. Bronze is softer than steel and the threads will gall or strip if you put an impact gun on it.
