Metallics JBLS25SS – Frequently Asked Questions
1) What size lag bolt is the Metallics JBLS25SS, and how many come in a jar?
The JBLS25SS is a 3/8 inch diameter by 4 inch long hex head lag bolt in 18-8 stainless steel, packed 50 to a jar. Thread count is 7 threads per inch, and the measured shank diameter runs 0.360 to 0.388 inch. Order minimum is 50 pieces, which is the jar.
2) Can I use stainless lag bolts like these outdoors or in a wet location?
Yes. The JBLS25SS lag bolt is 18-8 stainless steel, which Metallics rates as having superior corrosion resistance to galvanized steel lag bolts. That makes it the choice for exterior mounting, coastal or damp environments, and pressure-treated lumber where a zinc-plated bolt would bleed rust.
3) Does a 3/8 inch lag bolt need a pilot hole, or does it drive on its own?
The JBLS25SS is a full-bodied bolt with spaced threads and a gimlet point, so it starts itself in soft wood but it is not a self-drilling screw. In dense or dry lumber, drill a pilot hole for the 0.360 to 0.388 inch shank and drive it with a wrench or socket on the hex head. Stainless galls easily, so drive it slow.
4) Do Metallics JBLS25SS lag bolts qualify for Buy American or ARRA projects?
The JBLS25SS is flagged both ARRA compliant and Buy American compliant in Metallics' data. Country of origin is listed as multiple, so if your contract requires documented origin per shipment, request that paperwork with the order.
5) Do I need to order washers separately for these lag bolts?
Yes, washers are a separate line. The JBLS25SS jar is bolts only. Metallics lists a washer OD reference of 0.125 in. with the bolt, but no washer ships in the jar. For stainless work, pair it with a stainless flat washer so you do not set up galvanic corrosion with a plated washer.
6) I need a different length or diameter stainless lag bolt than 3/8 x 4. Are other sizes available?
Yes. Metallics builds this in the BLS and JBLS series, and other sizes and quantities are available by request. The JBLS prefix is the jar pack; BLS is the same bolt in other pack configurations.
7) How much does a jar of 50 of these 3/8 x 4 stainless lag bolts weigh?
The jar weighs 4.89 lbs and measures 4.5 x 7.25 x 4.5 inches. Worth knowing if you are stocking a truck or a shop bin by the case.
