Metallics JBLS25G – Frequently Asked Questions
1) What size lag bolt is the Metallics JBLS25G, and how many come in a jar?
It's a 3/8 by 4 inch hex head lag bolt, galvanized steel, packed 50 to a jar. Minimum order quantity is 50 pieces, so a jar is the base unit. Thread count is 7 threads per inch, right hand, with a shank outside diameter of 0.360 to 0.388 inch.
2) Can I use these galvanized lag bolts outdoors or in a damp mechanical room?
Yes. The galvanized finish on this 3/8 x 4 steel lag bolt is specifically for corrosive environments, which covers exterior work, damp mechanical rooms, and coastal or washdown areas. For dry interior work a plain or zinc plated lag does the same mechanical job at lower cost.
3) Are these lag bolts Buy American or ARRA compliant for a government job?
No. The JBLS25G is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. If your project has a domestic sourcing clause, this part will not clear it.
4) Can I use this lag bolt in concrete or masonry?
Not on its own. This is a full-bodied lag with spaced threads and a gimlet point, which is a wood fastener. To put it into concrete or block you'd need a lead or plastic lag shield sized for 3/8 inch, set in a drilled hole. Into bare concrete with no shield, it won't hold.
5) What pilot hole should I drill for a 3/8 inch lag bolt like this one?
Size the pilot to the shank, not the thread. The JBLS25G measures 0.360 to 0.388 inch across the body with a thread major diameter run of 0.620 to 0.650 inch, so in softwood you want a clearance hole through the top member at roughly 3/8 inch and a lead hole in the receiving member just under the shank diameter. The gimlet point lets it start without a full-depth lead hole in soft material; in dense hardwood or engineered lumber, drill the full lead depth or you'll snap heads.
6) Do these Metallics lag bolts meet a recognized dimensional standard for submittals?
They're built to ASME B18.2.1-1996 for dimensions, with material per AISI 1006 to 1022 steel, hardness Rockwell B70 to B100, and a minimum tensile strength of 60,000 psi. That's the data set a submittal reviewer usually asks for on a lag screw.
7) Do I need to add washers when installing these lag bolts?
Washers are not part of the jar, so order them separately if the connection calls for one. Metallics lists a washer OD of 0.125 in. against this item as a reference spec, but no washers are packed with the bolts themselves. Under a hex head on wood, a flat washer is standard practice to keep the head from crushing into the fiber.
8) How much does a jar of 50 of these 3/8 x 4 galvanized lag bolts weigh?
The packed jar weighs 5.34 lbs. The container itself runs 4.5 by 4.5 by 7.25 inches, which matters if you're loading a van shelf or a job box with several jars.
