Metallics JBLS34 – Frequently Asked Questions
1) What size lag bolt is the Metallics JBLS34, and how many come in a jar?
The JBLS34 is a 1/2 inch by 6 inch hex head lag bolt, zinc plated steel, packed 25 to a jar. Order minimum is 25 pieces, so one jar is the smallest buy.
2) Can I use these zinc lag bolts outdoors or in a treated-lumber or coastal install?
No. The zinc plated steel JBLS34 lag bolt is specified for use in wood in non-corrosive environments only. Pressure treated lumber, wet exteriors, and salt air will eat the zinc plating, so for those openings go with a hot dip galvanized or 18-8 stainless lag of the same 1/2 x 6 size instead.
3) What size pilot hole and socket do I need for a 1/2 inch Metallics lag bolt?
Drive it with a 3/4 inch socket or wrench. The hex head measures 0.725 to 0.750 inch across the flats, which is the standard 3/4 inch wrench size. For the pilot, the shank outside diameter runs 0.482 to 0.515 inch, so the pilot should clear the unthreaded shank and be undersized through the holding member for the threads to bite. The gimlet point starts the bolt, but a 6 inch lag in dense wood still wants a pilot to avoid splitting.
4) Does the Metallics JBLS34 lag bolt qualify for Buy American or ARRA funded work?
No. The JBLS34 is listed as not Buy American compliant and not ARRA compliant, with country of origin shown as multiple. If you are on a federally funded job with domestic sourcing requirements, this bolt will not satisfy it and you need a domestically produced lag.
5) Is the Metallics JBLS34 strong enough for hanging unistrut, conduit racks, or HVAC equipment from wood framing?
It is a full bodied lag bolt rated at 60,000 psi minimum tensile with a hardness of Rockwell B70 to B100, made from AISI 1006 to 1022 steel, and it is specified for the electrical, plumbing, heating and air conditioning trades. That is standard commercial grade lag bolt strength for anchoring strut, hangers, pipe clamps and equipment bases into wood. For load calculations on suspended equipment, work from the engineer's withdrawal values for the species of lumber, not the bolt tensile alone.
6) Does this lag bolt meet a recognized dimensional standard for submittals?
Yes, the JBLS34 is manufactured to ASME B18.2.1-1996 for dimensions, with AISI 1006 to 1022 steel per its material standard. That is the citation to put on a submittal when the spec calls for a standard hex lag screw.
7) Are these lag bolts right hand thread, and what is the thread pitch?
Right hand thread, 6 threads per inch. Spaced coarse threads like that are what a lag needs to grip wood fiber, and they are not intended to take a nut. If you need a bolt that threads through and takes a nut and washer, you want a hex cap screw or a carriage bolt, not this lag.
8) Can I get this Metallics hex lag bolt in other lengths or diameters than 1/2 x 6?
Yes. The BLS and JBLS series carries other sizes and quantities by request beyond the 1/2 x 6 JBLS34. If you are standardizing a facility on one lag for strut and hanger work, ask for the size and pack count you need in the same zinc plated steel.
