Metallics JBLS41 – Frequently Asked Questions
1) Can I use the Metallics JBLS41 5/16 x 1 inch lag bolt in concrete or masonry?
No. The JBLS41 is a wood lag bolt, full-bodied with a hex head, spaced threads and a gimlet point, and it's made for driving into wood. For block, brick or concrete you need a masonry anchor or a lag screw used with a lead or plastic shield, not this bolt on its own.
2) Is a zinc-plated steel lag bolt OK for outdoor or damp locations?
Not really. The JBLS41 is steel with a zinc finish and is specified for use in non-corrosive environments, so keep it to dry interior framing, strut backing, and similar protected work. For exterior, pressure-treated lumber or wet locations, step up to hot-dip galvanized or 18-8 stainless lags.
3) What size pilot hole and driving tool do I need for a 5/16 inch hex lag bolt?
Shank diameter on the JBLS41 runs 0.298 to 0.324 inch, so a pilot hole in the 3/16 to 7/32 inch range in softwood is the usual call for this diameter. Drive it with a wrench or socket, not a screwdriver: the hex head measures 0.484 to 0.500 inch across the flats, which a 1/2 inch socket or wrench fits.
4) Does the JBLS41 lag bolt qualify for Buy American or ARRA-funded projects?
No. The JBLS41 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If your job carries domestic sourcing requirements, this bolt will not satisfy them.
5) How many bolts come in a jar of Metallics JBLS41, and can I buy fewer?
The JBLS41 ships as a jar of 100, and the jar is the order minimum, so 100 pieces is the smallest quantity. Other sizes and quantities in the BLS and JBLS lag bolt line are available by request.
6) What strength and dimensional standards does this Metallics lag bolt meet?
Minimum tensile strength is 60,000 psi, hardness runs Rockwell B70 to B100, and the steel is AISI 1006 to 1022. Dimensions conform to ASME B18.2.1-1996. That's the data to put against a submittal for hanging strut, conduit straps, or equipment brackets on wood.
7) What is the thread pitch on the Metallics 5/16 lag bolt, and is it right-hand thread?
Nine threads per inch, right-hand, which is standard for a 5/16 inch lag. Spaced threads like these cut their own hold in wood, so there is no nut involved and nothing to tap.
8) Should I use a washer with these lag bolts?
Yes, for anything bearing directly on wood or on a soft bracket, a flat washer under the hex head spreads the load and keeps the head from crushing the surface. The washer dimension given for this bolt is 0.125 in. Washers are not included in the jar of 100, so order them separately.
9) What trades normally stock the Metallics BLS and JBLS lag bolts?
They're carried as an electrical-department fastener but the stated field application covers the electrical, plumbing, heating and air conditioning industries. In practice that means mounting straps, hangers, strut, panel backing and equipment brackets to wood framing, which is why MRO and multi-family crews keep a jar on the truck.
