Metallics BBH70 – Frequently Asked Questions
1) Is the Metallics BBH70 hex bolt silicon bronze all the way through, or just a bronze coating?
Solid silicon bronze, not a plated or coated steel bolt. The material conforms to ASTM F468, the standard covering nonferrous bolts and screws for general use, and the bronze appearance is the base metal itself. That matters for grounding and outdoor electrical work where you want a corrosion-resistant, non-magnetic fastener that stays compatible with bronze or copper hardware.
2) What thread does the BBH70 bolt take, and will a standard 5/8 nut thread onto it?
It's a 5/8-11 bolt, 11 threads per inch, cut to the ANSI/ASME B1.1 unified thread standard. That's standard 5/8 UNC coarse thread, so any off-the-shelf 5/8-11 nut or tapped 5/8-11 hole will accept it. For a bronze assembly, pair it with a silicon bronze nut rather than plain steel so you aren't mixing dissimilar metals in a wet location.
3) Can I use the BBH70 on a Buy American or ARRA-funded job?
No. The BBH70 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your contract carries a domestic sourcing clause, this bolt won't satisfy it and you'll need a domestically produced silicon bronze fastener instead.
4) What size wrench or socket fits the BBH70 hex head?
Head width across flats runs 0.922 to 0.938 inch, which is the standard hex for a 5/8 inch bolt, so a 15/16 inch wrench or socket is the right tool. Head height is 0.378 to 0.403 inch, worth knowing if you're working in a tight box or against a close obstruction.
5) How are these 5/8-11 bronze bolts packaged, and what's the smallest quantity I can buy?
They ship in a jar of 100, and 100 count is the order minimum, so one jar is the smallest buy. That packaging suits a shop shelf or a service truck better than a loose bag. Other sizes and quantities can be arranged by request.
6) Why choose a silicon bronze hex bolt over galvanized or stainless for an outdoor electrical connection?
Silicon bronze is picked where the bolt is landing on bronze or copper parts, grounding lugs, ground rod clamps, bonding straps, water-contact or marine hardware. It resists corrosion in wet and buried service and it won't set up the galvanic reaction you get by driving a steel or galvanized bolt into a copper or bronze fitting. Stainless is stronger, but in a copper assembly bronze keeps the metals compatible. The BBH70 covers the 5/8-11 by 2-1/4 inch size in that family.
7) Is the 2-1/4 inch length of the BBH70 fully threaded?
Order the BBH70 by its stated size, 5/8-11 by 2-1/4 inch, measured from under the hex head to the end of the bolt. On a 5/8 diameter bolt at that short a length, ASME B18.2.1 thread lengths typically run most of the shank, so plan your grip around the 2-1/4 inch overall and allow for nut and washer thickness when you size the joint.
8) What is the Metallics part number for the 5/8-11 x 2-1/4 silicon bronze hex bolt?
Metallics BBH70. That single part number covers the 5/8-11 by 2-1/4 inch silicon bronze hex bolt in the 100 count jar, so distributors and purchasing can order against it without a size suffix.
