Metallics JBLS18G – Frequently Asked Questions
1) What size pilot hole do I need for a 5/16 x 5 inch hex lag bolt?
The Metallics JBLS18G is a 5/16 inch diameter lag bolt, with a measured outside (thread) diameter of 0.298 to 0.324 inch and 9 threads per inch. A lag that size needs a pilot drilled to roughly the shank diameter under the threads in solid wood, so you're drilling smaller than 5/16 inch and letting the spaced threads cut their own purchase. The gimlet point starts the bolt in the hole, but at 5 inches of length in dense lumber a pilot hole is what keeps the head from snapping off.
2) Can these galvanized lag bolts be used outdoors or in treated lumber?
Yes. The JBLS18G is galvanized steel and the series is intended for corrosive environments, which is what you want for exterior framing, ledgers, fence posts, and contact with pressure treated lumber. If you need a higher level of corrosion resistance than zinc for coastal or submerged work, step up to stainless rather than galvanized.
3) How strong is this lag bolt, and is it hardened?
Minimum tensile strength is 60,000 psi, with hardness in the Rockwell B70 to B100 range, made from AISI 1006 to 1022 low carbon steel. That's standard unhardened lag screw material, dimensioned to ASME B18.2.1-1996. It is a structural wood fastener, not a graded high strength bolt, so don't substitute it where a drawing calls for a Grade 5 or Grade 8 bolt.
4) How many lag bolts come in a jar, and can I buy fewer than 100?
The JBLS18G ships as a jar of 100, and 100 count is the order minimum, so that jar is the smallest buy. The jar packaging is practical on a service truck since the bolts stay contained instead of loose in a bin. Other sizes and quantities in the BLS and JBLS series are available by request.
5) Is this lag bolt fully threaded, and how deep will it actually bite?
It's a full bodied lag with spaced threads and a hex head, 5 inches overall length measured from under the head. Lags of this pattern carry thread over part of the length with an unthreaded shank up near the head, so your embedment into the receiving member is what holds, not the thickness of the piece you're bolting through. Size it so at least half the length lands in the structural member.
6) Does the Metallics JBLS18G lag bolt qualify for Buy American or ARRA jobs?
Metallics lists the JBLS18G as ARRA compliant and Buy American compliant, with country of origin China. On a federally funded job, hand both of those to your compliance reviewer, because the governing clause on your contract decides whether a China origin item clears.
7) What does a jar of 100 of these 5/16 x 5 lag bolts weigh for shipping?
A jar of 100 weighs 9.05 lbs. Worth knowing if you're stacking several sizes on one order or carrying them up a ladder on a repair call.
