Metallics JBLS21G – Frequently Asked Questions
1) What size lag bolt is the Metallics JBLS21G, and how many come in a jar?
It's a 3/8 by 2 inch hex head lag bolt, galvanized steel, packed 50 to a jar. Minimum order is 50 each, so the jar is the buying unit. Measured shank outside diameter runs 0.360 to 0.388 inch and thread pitch is 7 threads per inch, right hand.
2) Can these galvanized lag bolts be used outdoors or in a damp mechanical room?
Yes. The galvanized finish on these 3/8 inch steel lag bolts is specified for use in corrosive environments, which covers exterior mounting, rooftop work, and wet or humid mechanical and equipment rooms. For dry indoor framing a plain zinc lag does the same mechanical job, but the galvanized coating is what you want anywhere moisture reaches the fastener.
3) Are the Metallics JBLS21G lag bolts Buy American or ARRA compliant for a government job?
No on both counts. The JBLS21G is not Buy American compliant and not ARRA compliant, with country of origin listed as multiple. If your project has domestic sourcing requirements written into the contract, these will not satisfy them and you need a domestically produced lag.
4) Do I need to drill a pilot hole for a 3/8 x 2 inch lag bolt?
These are full-bodied lag bolts with spaced threads and a gimlet point, so they start themselves, but in solid lumber a pilot hole is still standard practice at 3/8 inch diameter to avoid splitting the wood and snapping the shank. The shank body runs 0.360 to 0.388 inch, so size the pilot to the root of the thread, not the outside diameter.
5) What is the tensile strength and hardness of these Metallics lag bolts?
Minimum tensile strength is 60,000 psi with hardness of Rockwell B70 to B100, made from AISI 1006 to 1022 low carbon steel. That is standard commercial lag bolt material, fine for hanging conduit, strut, equipment supports and general framing attachment. For a structural connection called out on drawings at a higher grade, check the spec, this is not a high strength alloy bolt.
6) Are washers included with these lag bolts?
Nothing but the bolts ships in the jar of 50. Lags bearing on wood or on a thin bracket normally want a flat washer under the head to spread the load, so order washers separately for the 3/8 inch shank.
7) I need a different length or diameter lag in the same galvanized finish. Is that available?
The BLS and JBLS series covers other sizes and quantities beyond the 3/8 by 2 inch jar of 50, available by request. Specify diameter, length and pack size, the JBLS prefix is the jar-packed version of the same galvanized hex lag.
