Metallics JBBH48 – Frequently Asked Questions
1) Why use a silicon bronze hex bolt instead of galvanized or stainless steel?
Silicon bronze is the usual pick where corrosion and galvanic reaction matter, like marine air, wet electrical gear, or fastening to bronze and copper components where a steel bolt would set up dissimilar-metal corrosion. The JBBH48 is solid silicon bronze with a bronze finish, made to ASTM F468 for nonferrous bolting material, so the corrosion resistance is in the metal rather than a coating that can be scratched off during install.
2) Can I use these bronze bolts on a federally funded job with Buy American requirements?
No. The JBBH48 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your contract carries a domestic-sourcing clause, this bolt will not satisfy it and you need a domestically produced silicon bronze fastener instead.
3) What wrench or socket size fits the head of the Metallics JBBH48 bolt?
Head width across flats measures 0.428 to 0.438 inch, which is a 7/16 inch wrench or socket. Head height runs 0.150 to 0.163 inch. Dimensions follow ASME B18.2.1, so it drives like any standard 1/4 inch hex bolt and nothing special is needed in the tool bag.
4) Is the JBBH48 the right length if I need something longer in the same bronze bolt?
The JBBH48 is fixed at 5/8 inch under the head in 1/4-20. It is part of the Metallics BBH and JBBH series of silicon bronze hex bolts, and other sizes and quantities are available by request, so a longer shank in the same material and thread can be sourced within the series rather than switching to a different metal.
5) What trades actually use a 1/4-20 silicon bronze hex bolt like this?
Metallics lists the application as the electrical, plumbing, heating and air conditioning industries. In practice that means grounding and bonding connections, bronze valve and pump hardware, water-side equipment, and any wet or coastal mechanical room where a plated steel bolt would bleed rust within a season.
