Metallics JBLS24SS – Frequently Asked Questions
1) What size lag bolt is the Metallics JBLS24SS, and how many come in a jar?
JBLS24SS is a 3/8 inch diameter by 3-1/2 inch hex head lag bolt in 18-8 stainless steel, packed 100 to a jar. The jar of 100 is also the minimum order quantity, so you buy it by the count rather than by the piece.
2) Will stainless lag bolts hold up outdoors or in a wet location better than galvanized?
Yes. The 18-8 stainless lag bolt has better corrosion resistance than a galvanized steel lag, which is why it gets specified for exterior strut, conduit supports, rooftop runs, pool and coastal work, and anywhere washdown or standing moisture is a factor.
3) What size hole do I drill for a 3/8 inch stainless lag bolt, and does it need a pilot hole?
Yes, pilot it. The shank measures 0.360 to 0.388 inches across and the threads run 7 per inch with a gimlet point, so it will start itself in soft wood but stainless lags gall and snap if you drive them dry into dense lumber. Drill a pilot slightly under the 0.360 inch minor shank size in hardwood or pressure treated framing, and use a lubricant on the threads.
4) How strong is this stainless lag bolt compared to a plated steel one?
Tensile strength runs about 100,000 to 125,000 psi minimum, with hardness in the Rockwell B95 to C32 range. That puts it well above a standard low carbon plated lag for pull-out and shear duty, and it is a full-bodied bolt rather than a reduced-shank screw, so the shank carries load in the unthreaded section.
5) Are these lag bolts acceptable on a Buy American or ARRA funded project?
Yes, the JBLS24SS is flagged both ARRA compliant and Buy American compliant, which is what a government, school, or federally funded job will ask for in submittals. Country of origin is listed as multiple, so confirm the origin marking on the jar you receive if your spec requires a single named country.
6) Is a lag bolt the right fastener for anchoring into concrete or masonry?
No. This is a wood lag with spaced threads and a gimlet point, meant to bite into wood framing, blocking, or timber. For concrete, block, or brick you need a concrete screw anchor or an expansion anchor sized to the hole, not a lag, unless you are threading the lag into a lead or plastic shield set in the masonry.
7) Can I get this Metallics lag bolt in a different length or diameter, or in a bulk box instead of a jar?
Yes. The BLS and JBLS series runs other diameters, lengths, and pack quantities by request, with the JBLS prefix being the jar packs. If you are fastening thinner material or going deeper into framing than 3-1/2 inches, ask for the size you need rather than substituting a shorter embedment.
8) How much does a jar of 100 of these 3/8 x 3-1/2 stainless lags weigh for shipping?
The jar comes in at 9.06 lbs, with the carton measuring 4.5 by 4.5 by 7.25 inches. Worth knowing if you are staging multiple jars to a rooftop or a lift rather than carrying loose fasteners.
