Metallics SBH20 Bolts 1/4-20 x 3/4 HXBT SS (Box 50)

Yes. The SBH20 is made from 316 stainless steel, the molybdenum-bearing austenitic alloy that gives better corrosion resistance than 18-8 and better strength at elevated temperature. That makes it a reasonable pick for exterior strut, rooftop mechanical, wash-down areas and salt-air locations where plated carbon steel would bleed rust.

The SBH20 carries a tensile strength of 100,000 to 150,000 psi minimum and a yield strength of 65,000 psi minimum, with hardness in the Rockwell B95 to C32 range. That is in line with what stainless cap screws deliver for pipe hangers, strut, enclosure mounting and equipment anchoring. Stainless does not reach the strength of a Grade 8 carbon steel bolt, so if your drawing calls out a specific SAE grade rather than a stainless alloy, match the grade.

Metallics lists the SBH20 as both Buy American compliant and ARRA compliant. Country of origin is recorded as multiple, so if your contract requires documentation of the specific origin on the lot you receive, request it with the order.

The SBH20 ships as a box of 50 pieces, and 50 each is the order minimum, so it is bought by the box rather than loose. Metallics notes other sizes and quantities are available by request.

Metallics builds the SBHC and JSBHC stainless hex bolt series for the electrical, plumbing, and heating and air conditioning trades. Typical use is fastening boxes, straps, hangers, strut accessories and equipment where a corrosion-resistant stainless fastener is specified instead of zinc-plated steel.

Both 18-8 and 316 are austenitic stainless alloys, so they pair without the galvanic problem you would get mixing stainless with plated carbon steel. The SBH20 is the 316 version, which is the one to use where chlorides or high temperature are in play; 18-8 is the general-purpose choice indoors. One practical caution with any austenitic stainless: the threads gall if run down fast and dry, so use anti-seize and moderate speed.
