Metallics JBLS37 – Frequently Asked Questions

1) Is a 1 inch lag bolt long enough to hang an electrical panel or conduit strap on a stud?
At 1 inch overall length, the JBLS37 is a short lag. It is meant for thin brackets, straps, and mounting plates going straight into solid wood, where you only need roughly a half inch to three quarters of an inch of thread biting the stud. If you are fastening through drywall, sheathing, or a thick mounting board into framing behind it, this length will not reach far enough into the wood and you want a longer lag in the same series.
2) Do these Metallics lag bolts qualify for a Buy American or ARRA federal job?
No. The JBLS37 hex lag bolts are not Buy American compliant and are not ARRA compliant, with country of origin listed as multiple. If your federal, municipal, or grant-funded project carries a domestic sourcing clause, these will not satisfy it.
3) What wrench or socket size fits the head on this 1/4 inch lag bolt?
The hex head measures 0.425 to 0.438 inches across the flats, so a 7/16 inch socket or wrench is the right tool. Head height runs 0.150 to 0.188 inches. Use a socket rather than an open end if you are driving a hundred of them, since the drive is what takes the torque in wood.
4) Can I use these zinc lag bolts outdoors?
The zinc finish on these steel lag bolts is a corrosion-resistant coating suited to non-corrosive environments, so interior work and protected exterior locations are fine. Direct weather exposure, treated lumber, or coastal and chemical environments call for hot-dip galvanized or 18-8 stainless instead, not plain zinc.
5) Will these lag bolts hold in a structural connection, and what is the steel rated at?
These are carbon steel lags made from AISI 1006-1022 stock with a 60,000 psi minimum tensile strength and Rockwell B70-B100 hardness. That is standard low-carbon lag screw material, good for wood-to-wood framing connections, equipment mounts, and bracket work. They are not a graded structural bolt, so if a drawing calls out a bolt grade with a nut and washer, this is a different fastener.
6) Can I use a lag bolt like this into concrete or masonry?
No. This is a wood fastener with a gimlet point, intended for solid lumber and wood framing. Anchoring to concrete, block, or brick requires a masonry anchor or a lag shield sized to the 1/4 inch bolt; driving the lag straight into masonry will not hold.
7) How many lag bolts come in a jar and can I buy a smaller quantity?
They ship in a jar of 100, and 100 pieces is the order minimum, so a jar is the smallest unit sold. The filled jar weighs 703 grams, a little over a pound and a half.
8) Which trades commonly stock this 1/4 inch hex lag bolt?
It is carried for the electrical, plumbing, heating, and air conditioning trades: panel and bracket mounting, conduit and pipe support attachment, and ductwork hangers into wood framing. Maintenance crews keep the 100-count jar on the truck for the same reason, since one size covers most strap and bracket work on studs.
