Metallics SBH985 – Frequently Asked Questions
1) What thread does the Metallics SBH985 hex bolt take, and what nut do I need?
The SBH985 is a 3/4-10 hex bolt, meaning a 3/4 inch nominal diameter with 10 threads per inch, which is standard UNC coarse thread. Any 3/4-10 UNC nut or tapped hole will take it. Measured shank diameter runs 0.7410 to 0.7500 inch. For corrosion matching, pair it with a stainless nut and washer rather than plain steel.
2) Is the SBH985 bolt 18-8 or 316 stainless?
18-8 stainless steel. Both 18-8 and 316 are austenitic alloys suited to general atmospheric corrosion resistance, but 316 is the one specified where chloride or aggressive chemical exposure is a factor. If you are bolting near salt spray, a pool chemical room, or a wash-down area with harsh cleaners, specify 316 instead of this 18-8 bolt.
3) How strong is an 18-8 stainless 3/4 inch hex bolt compared to a grade 5 zinc bolt?
Tensile strength on this one 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 well below a Grade 5 or Grade 8 carbon steel bolt on yield, so if your drawing calls out a structural grade, stainless is not a straight swap. Stainless is chosen here for corrosion resistance, not for load.
4) What wrench or socket size fits the head on this 3/4-10 stainless hex bolt?
The hex head measures 1.100 to 1.125 inches across the flats, so a 1-1/8 inch wrench or socket is the correct size. Head height is 15/32 inch, with a wrenching height of 0.324 inch, so you need roughly a third of an inch of clear engagement for the socket to seat properly in a recessed or counterbored location.
5) Does the Metallics SBH985 come loose or in a box, and is there a minimum order?
It ships as a box of 20 pieces, and 20 each is the order minimum. There is no single-piece option, so for a two-bolt repair you will still be buying the full box. Metallics does offer other sizes and quantities on request if 3/4-10 x 3-1/2 in a 20-count is not what the job needs.
6) Can I use this stainless hex bolt on a Buy American or ARRA funded job?
Metallics lists the SBH985 as both ARRA compliant and Buy American compliant, which is what a government, school district, or transit procurement officer needs on the submittal. Country of origin is recorded as multiple, so if your specification demands a single named origin, confirm the origin on the lot you are supplied.
7) What are these 3/4-10 stainless hex bolts typically used for?
Metallics targets the SBHC and JSBHC hex bolt line at electrical, plumbing, heating and air conditioning work, so typical uses are anchoring strut, hanging pipe and duct supports, mounting transformers and large enclosures, and similar equipment attachment. The 18-8 stainless makes it a fit for chemical and food-processing equipment where general atmospheric corrosion resistance is required.
