Metallics JSBH341 – Frequently Asked Questions
1) What thread and diameter are the Metallics JSBH341 hex bolts, and will they take a standard 1/2-13 nut?
They are 1/2-13, meaning a 1/2 inch nominal diameter with 13 threads per inch (UNC coarse). Measured shank outside diameter runs 0.4930 to 0.5000 inch, so any standard 1/2-13 UNC nut or tapped hole will take them. Length is 2-1/2 inches.
2) Are these 316 stainless or 18-8 stainless bolts?
The JSBH341 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, chemical, and exterior work where 18-8 would pit.
3) Will these bolts meet a Buy American or ARRA requirement on a public job?
No. The JSBH341 is not Buy American compliant and is not ARRA compliant, with multiple countries of origin. On a federally funded or domestic-preference spec you need a domestic-sourced fastener instead.
4) What wrench or socket size fits these 1/2-13 hex bolts?
Head width across flats measures 0.736 to 0.750 inch, so a 3/4 inch wrench or socket is the fit.
5) How strong are these stainless hex bolts, and are they strong enough to replace a grade 5 zinc bolt?
Tensile strength is 100,000 to 150,000 psi minimum with a 65,000 psi minimum yield, and hardness runs Rockwell B95 to C32. That is a corrosion-first fastener: it has real load capacity but a lower yield than a typical heat-treated carbon steel structural bolt, so for a stated structural load use the engineer's specified grade. Where the governing concern is rust in a damp or exterior location, this is the swap people make.
6) How many bolts come in a jar of Metallics JSBH341, and is there a minimum order?
Each jar holds 50 bolts, and 50 each is the order minimum, so a single jar is the smallest buy.
7) Do nuts or washers come with these Metallics hex bolts?
No. The jar is bolts only, 50 hex bolts in 1/2-13 x 2-1/2. Order 1/2-13 nuts and 1/2 inch flat and lock washers separately, and match them in 316 stainless if you want the corrosion resistance to hold up, mixing carbon steel hardware onto a stainless bolt gives you a rust point and galvanic issues.
8) Can I get this Metallics hex bolt in a different length or a bigger quantity?
Yes. The SBHC and JSBHC series covers other diameters, lengths and pack quantities beyond the 1/2-13 x 2-1/2 jar of 50, available by request.
