Metallics JBLS15SS – Frequently Asked Questions

1) Will a 5/16 x 3-1/2 stainless lag bolt hold up outdoors or near salt air?
The Metallics JBLS15SS lag bolt is 18-8 stainless steel, which Metallics rates as having superior corrosion resistance to galvanized steel bolts. That makes it the pick for exterior mounting, damp or washdown areas, and treated lumber where a plain or zinc-plated lag would corrode.
2) What size drill bit and pilot hole does a 5/16 inch hex lag bolt need?
The JBLS15SS measures 0.298 to 0.324 inch on the outside diameter over the threads with 9 threads per inch, so size the pilot to the shank root, not the thread crest. In solid wood a 5/16 lag typically takes a 3/16 to 7/32 inch pilot; in softer material you can go smaller for more thread bite. Pre-drilling matters here because this is a full-bodied bolt with a gimlet point, not a self-drilling screw.
3) Are these stainless lag bolts Buy American and ARRA compliant for a government job?
Metallics lists the JBLS15SS as both Buy American compliant and ARRA compliant, which is what public agency, school district and federally funded work usually requires on the fastener line. Country of origin is listed as multiple.
4) Can I use a lag bolt like this into concrete or masonry?
Not on its own. A hex lag bolt with spaced threads and a gimlet point is a wood fastener. To land it in concrete or block you need a lead or plastic lag shield sized for 5/16, set in a drilled hole, and the lag threads into that. Straight into masonry without a shield it will not hold.
5) What wrench or socket size fits the head on this Metallics lag bolt?
Head width across flats runs 0.484 to 0.500 inch, so a 1/2 inch socket or wrench is the right fit. It is a hex head, so it drives with a socket and ratchet or an impact with a 1/2 inch hex driver rather than a screwdriver bit.
6) Is this lag bolt strong enough for structural or heavy equipment mounting?
Tensile strength on the JBLS15SS is approximately 100,000 to 125,000 psi minimum with a hardness of Rockwell B95 to C32. That is a load-bearing fastener suited to hanging strut, equipment brackets, ledgers and conduit supports. For anything the drawing calls out as structural, match the stated values against the engineer's required capacity.
7) Do these lag bolts meet a recognized dimensional spec for submittals?
Head and body dimensions conform to ASME B18.2.1-1996, the standard for square and hex bolts and screws. That is the line to put on a submittal when a spec calls for dimensionally standard hex lag bolts.
8) How many 5/16 x 3-1/2 stainless lag bolts come in a jar, and can I buy fewer?
These ship 50 to a jar, and 50 each is the order minimum, so a jar is the smallest buy. Metallics offers other sizes and quantities in the BLS and JBLS lag bolt series by request if 5/16 x 3-1/2 is not the length you need.
9) Do washers come with the Metallics JBLS15SS lag bolts?
No washers are included; the jar of 50 is bolts only. Order stainless washers separately and match the material so you do not pair stainless with plated steel in a wet location, which invites galvanic corrosion. Order the part number JBLS15SS for the bolts themselves.
