Metallics JBLS3G Bolts 1/4 X 2-1/2 Hx Lag Blt Galv (Jar 100)

Yes. The JBLS3G lag bolt is galvanized steel and is called out for use in corrosive environments, so exterior walls, damp mechanical rooms, and coastal or wash-down areas are fair game. For dry indoor work a plain zinc lag does the same mechanical job, but once moisture is in the picture the galvanized coating is what keeps the shank from rusting out of the wood.

The JBLS3G has a gimlet point, so it will start itself in soft wood, but it is a full-bodied lag with spaced threads and a hex head meant to be driven with a wrench, not a drill-point screw. In framing lumber, pressure-treated stock, or anywhere near an edge, drill a pilot sized to the 0.237 to 0.260 inch shank to avoid splitting and to keep from shearing the head.

The JBLS3G is flagged compliant for both Buy American and ARRA purposing, with country of origin China. Institutional and government buyers working to a Buy American clause should match those flags against the specific clause on their contract, since the compliance basis and the origin both get reviewed.

They ship as a jar of 100 pieces, and 100 count is the order minimum. The jar packaging keeps them together on a cart or in a gang box rather than loose in a bin. Other diameters and lengths in the BLS and JBLS lag series, and other pack quantities, are available by request.

No. The JBLS3G is a wood lag: spaced threads and a gimlet point that cut into timber. Driven into concrete, block, or brick it will not hold. For masonry you want a concrete screw anchor, a sleeve or wedge anchor, or a lag shield insert that the lag threads into. Use these in wood framing, plywood backing, or timber.
