Metallics JBLS346G Bolts 3/4 X 6 Hx Lag Blt Galv (Jar 10)

Yes. The Metallics JBLS346G is a galvanized steel lag bolt specifically called out for use in corrosive environments, so exterior framing, docks, treated-lumber connections, and damp mechanical rooms are all in scope. Base metal is steel with a galvanized finish.

The JBLS346G is flagged as both ARRA compliant and Buy American compliant in the manufacturer data. Country of origin on the part is China, so if your specification requires domestic melt and manufacture rather than the compliance flag, confirm against your contract language before submitting.

Dimensions follow ASME B18.2.1-1996, the material is carbon steel in the AISI 1006 to 1022 range, minimum tensile strength is 60,000 psi, and hardness runs Rockwell B70 to B100. That is standard commercial-grade lag bolt stock, not a high-strength structural bolt, so if the drawing calls for a specific bolt grade, check the number against the 60,000 psi minimum.

Size the pilot off the shank, not the thread. The JBLS346G runs 0.729 to 0.768 inch outside diameter over the threads, and the unthreaded body falls in that 3/4 inch nominal range, so you want a lead hole sized to the root of the thread in the wood and a clearance hole through the top member. The bolt has a gimlet point, so it draws itself in once the lead hole is started, but at 3/4 x 6 it needs a wrench, not a drill driver.

The hex head measures 1.088 to 1.125 inches across the flats, which is a 1-1/8 inch socket or wrench. Plan on an impact wrench or a long breaker bar for 6 inch lags in solid lumber.

The 3/4 x 6 galvanized hex lag bolts ship in a jar of 10, and 10 count is the order minimum, so one jar is the smallest buy. Metallics does offer other sizes and quantities of this lag bolt on request.

Full-bodied. The JBLS346G has a hex head, spaced threads, a gimlet point, and an unreduced shank, which is what lets it carry withdrawal load in wood rather than acting as a sheet metal screw. Overall length is 6 inches.
