Metallics SBH986 – Frequently Asked Questions
1) What thread and size is the Metallics SBH986 hex bolt, and what wrench size does the head take?
The SBH986 is a 3/4-10 hex bolt, 4 inches long, so it is coarse thread at 10 threads per inch. Shank outside diameter runs 0.7410 to 0.7500 in. Across-flats head width is 1.100 to 1.125 in., which is a 1-1/8 inch wrench, and head height is 15/32 in. Mating nuts and tapped holes must be 3/4-10 UNC, not 3/4-16 fine.
2) Is this stainless bolt 18-8 or 316, and will it hold up outdoors on a rooftop unit?
It is 18-8 stainless steel. That grade handles general atmospheric corrosion, which covers typical outdoor and rooftop mechanical mounting, plus chemical and food-processing equipment. It is not the 316 molybdenum grade, so in marine salt spray or aggressive chemical exposure you want a 316 bolt instead.
3) How strong is a 3/4-10 stainless hex bolt like the SBH986 compared to a Grade 5 steel bolt?
Tensile strength is 85,000 to 140,000 psi minimum with a 45,000 psi minimum yield, and hardness runs Rockwell B80 to C32. That puts it below a Grade 5 carbon steel bolt on yield, so if a structural connection is engineered for Grade 5 or Grade 8 you cannot swap stainless in without checking the load. Stainless is chosen here for corrosion resistance, not for maximum strength.
4) How many bolts come in a box of Metallics SBH986, and can I buy just a few?
They ship as a box of 20, and the order minimum is 20 each, so 20 is the smallest quantity. Metallics notes other sizes and quantities are available by request if 3/4-10 x 4 in a 20-count box is not what your job needs.
5) Do these hex bolts come with nuts and washers?
No. The SBH986 is bolts only, 20 hex bolts to the box. Order 3/4-10 stainless hex nuts and 3/4 stainless flat and lock washers separately, and keep them in 18-8 to avoid mixing dissimilar metals in the joint.
6) Are Metallics SBH986 stainless bolts acceptable on a Buy American or ARRA funded project?
Both the ARRA Compliant and Buy American Compliant fields are flagged C for this bolt, and country of origin is listed as multiple (MUL). For a federally funded job, submit those compliance flags with your product data to the specifying authority along with the origin on the shipment you receive.
7) What are these 3/4-10 stainless hex bolts typically used for in the trades?
Metallics lists the field application as the electrical, plumbing, heating and air conditioning industries. In practice that is anchoring strut and channel assemblies, equipment bases, hanger and support steel, and pipe or duct supports where the fastener is exposed to weather or washdown and a plated carbon bolt would rust.
