Metallics JSBH990 – Frequently Asked Questions
1) What thread size and pitch is the Metallics JSBH990 hex bolt?
The JSBH990 is a 3/4-10 hex bolt, meaning 3/4 inch nominal diameter with 10 threads per inch (coarse UNC). Measured shank diameter runs 0.7410 to 0.7500 inch, so it mates with standard 3/4-10 nuts and tapped holes. Grip length is 1 inch.
2) Is 316 stainless worth it over 18-8 for outdoor or wet electrical work?
For coastal, wash-down, or chemically exposed runs, yes. The JSBH990 is 316 stainless, and the molybdenum in 316 gives it greater corrosion resistance than 18-8 plus better strength at elevated temperature. Both are austenitic alloys, so if the bolt is indoors and dry, 18-8 covers it; 316 is what you spec when salt or chemicals are in play.
3) How strong is a 316 stainless hex bolt compared to a plated steel grade bolt?
The JSBH990 carries a minimum tensile strength of 85,000 to 140,000 psi and a minimum yield of 45,000 psi, with hardness Rockwell B80 to C32. That puts it in the range of a general-purpose fastener, not a high-strength structural one. If your drawing calls out an SAE Grade 5 or Grade 8 bolt for a load-bearing connection, stainless of this class is not the substitute; use it where corrosion resistance is the governing requirement.
4) Can I use the Metallics JSBH990 bolt on a federally funded or Buy American job?
No. The JSBH990 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 will not satisfy it and you need a domestically produced fastener instead.
5) What wrench size fits the head on this 3/4-10 stainless hex bolt?
Head width across flats on the JSBH990 measures 1.100 to 1.125 inches, so a 1-1/8 inch wrench or socket is the fit. Head height is 15/32 inch, which matters if you are working in a shallow channel or under a clamp where socket clearance is tight.
6) How are these Metallics 3/4-10 stainless bolts packaged, and is there a minimum order?
They ship in a jar of 25. The order minimum is 100 jars, so plan quantities in jar multiples rather than piece counts. Other sizes and quantities can be had by request.
7) Where do contractors typically use these 316 stainless hex bolts?
They are intended for the electrical, plumbing, and heating and air conditioning trades: strut and channel connections, equipment mounting, hanger and support assemblies, anywhere a 3/4-10 through-bolt is called for. With only 1 inch of length under the head, this size suits thin stacked material or a tapped hole rather than a deep clamped joint.
