Metallics SBH680 – Frequently Asked Questions
1) Is the Metallics SBH680 hex bolt 316 stainless or 18-8 stainless?
The SBH680 is 316 stainless steel. The molybdenum in 316 gives it greater corrosion resistance than 18-8 and better strength at elevated temperatures, which is why it gets specified for coastal, wash-down, and chemical-exposure work rather than plain indoor framing.
2) What thread does the 5/8 Metallics hex bolt take, and will it run into a standard 5/8 nut?
It is 5/8-11, meaning 11 threads per inch, which is standard coarse (UNC) for 5/8 inch. Any 5/8-11 nut or tapped hole will take it. Measured thread outside diameter runs 0.6170 to 0.6250 inch.
3) Do these Metallics SBH680 bolts qualify for a Buy American or ARRA-funded project?
No. The SBH680 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. For federally funded work carrying domestic sourcing requirements you will need a domestically produced 5/8-11 stainless hex bolt instead.
4) How strong is a 316 stainless hex bolt compared to a plated steel grade 5?
The SBH680 is rated 100,000 to 150,000 psi minimum tensile with 65,000 psi minimum yield, and hardness of Rockwell B95 to C32. That is a corrosion-first fastener, not a high-strength structural one, so if your drawing calls for a specific SAE or ASTM structural grade, check the spec before substituting stainless.
5) How are these bolts packaged, and is there an order minimum?
They ship as a box of 25, and the order minimum is 50 each, so a purchase comes out to two boxes. Other sizes and quantities are available by request.
6) What kind of jobs are these Metallics stainless hex bolts intended for?
They are catalogued for electrical, plumbing, heating and air conditioning work, so think strut and channel anchoring, equipment mounting, hanger and pipe support assemblies, and rooftop or mechanical room fastening where moisture makes plated steel a callback.
