Metallics SBH16B – Frequently Asked Questions
1) Are the Metallics SBH16B hex bolts stainless steel, and will they hold up outdoors or in a wash-down area?
The SBH16B hex bolt is made from 18-8 stainless steel, an austenitic alloy used where general atmospheric corrosion resistance is needed, including chemical and food-processing equipment. That covers typical exterior and wash-down duty. Aggressive chemical exposure can call for 316 or another specialty alloy instead, so match the alloy to the chemistry on site rather than assuming 18-8 covers everything.
2) What size is the Metallics SBH16B bolt?
It is a 1/2-13 x 4-1/2 inch hex bolt in stainless steel. The 4-1/2 inch length is measured under the head, so account for your total clamped thickness plus the nut and any washers when you size the grip.
3) How many bolts come in a box of Metallics SBH16B, and can I buy a smaller quantity?
The SBH16B ships as a box of 2,500 pieces, and 2,500 each is the order minimum. Other sizes and quantities are available by request, so if a 2,500-piece box is more than the job needs, ask about an alternate pack.
4) Will these Metallics stainless bolts satisfy a Buy American requirement on a federal or publicly funded job?
No. The SBH16B is listed as not Buy American compliant and not ARRA compliant, with country of origin reported as multiple. If your contract carries a domestic-sourcing clause, this is not the fastener to submit.
5) Do the SBH16B bolts come with nuts or washers?
No. The SBH16B is sold as hex bolts only, 2,500 to a box. Nuts and washers are separate, and for an 18-8 stainless bolt you want matching stainless nuts and washers so you do not set up galvanic corrosion between dissimilar metals at the joint.
6) Is the SBH16B the same as a 316 stainless cap screw?
Not the same alloy. The SBH16B is 18-8 stainless. Both 18-8 and 316 stainless cap screws are austenitic, but 316 adds molybdenum and is the choice for chloride or marine exposure. For general atmospheric corrosion resistance, 18-8 is the usual pick. Other sizes and materials in the SBHC and JSBHC series are available by request if the job calls for 316.
7) What wrench or socket do I need for these hex bolts?
The SBH16B takes a hex socket or open-end wrench across the flats. Head height is 13/64 inch with a wrenching height of 0.14 inch, so there is limited bearing surface for the wrench, use a six-point socket rather than a twelve-point to avoid rounding the corners. Stainless also galls easily when run down fast, so use anti-seize and moderate speed.
