Metallics JBLS11SS50 – Frequently Asked Questions
1) What size lag bolt is the Metallics JBLS11SS50, and how many come in the jar?
It's a 5/16 inch by 1-1/2 inch hex head lag bolt in 18-8 stainless steel, packed 50 to a jar. Thread count is 9 threads per inch, and measured shank outside diameter runs 0.298 to 0.324 inch.
2) Will stainless lag bolts hold up outdoors or in a damp mechanical room better than galvanized?
Yes. The 18-8 stainless construction gives better corrosion resistance than galvanized steel lag bolts, which is why it gets specified for exterior strut, conduit standoffs, and wet or washdown areas where galvanized coating eventually breaks down at the cut threads.
3) Do I need to drill a pilot hole for a 5/16 inch lag screw, or does it start on its own?
The JBLS11SS50 has a gimlet point and spaced wood-screw threads, so it starts itself in softer material, but a pilot hole is still standard practice in dense lumber. Shank diameter measures 0.298 to 0.324 inch and the thread pitch is 9 per inch, so size the pilot to the root of the thread, not the full shank, or the stainless will gall and twist off.
4) What wrench or socket size fits the head on this Metallics 5/16 lag bolt?
Head width across flats measures 0.484 to 0.500 inch, so a 1/2 inch socket or wrench is the fit. It's a hex head, made to ASME B18.2.1-1996 dimensional standard, so standard impact sockets seat correctly.
5) How strong is this stainless lag bolt compared with a plain steel one?
Tensile strength is listed at approximately 100,000 to 125,000 psi minimum with a hardness of Rockwell B95 to C32. That puts it in useful structural territory for hanging strut, conduit racks, and equipment, though stainless is softer in torsion than hardened carbon steel, so drive it with controlled torque rather than full impact.
6) Are these lag bolts acceptable on a Buy American or ARRA funded job?
The JBLS11SS50 is flagged as both ARRA compliant and Buy American compliant in the manufacturer data, with country of origin listed as China. On federally funded work, confirm which clause your contract invokes, since those two designations are not the same test.
7) Is there a minimum order quantity on Metallics JBLS lag bolts?
Order minimum is 100 count. Since the bolts come 50 to a jar, that works out to two jars as the smallest order.
8) Should I use a washer with these stainless lag bolts?
A washer is normally used under the hex head of a lag bolt so the head does not crush into the wood or pull through sheet material. The listed washer OD reference for this item is 0.125 inch; for structural attachments spec a stainless flat washer sized to a 5/16 bolt so you don't mix metals and set up galvanic corrosion against the 18-8 stainless.
