Metallics JBLS41G – Frequently Asked Questions
1) Can a 5/16 x 1 inch galvanized lag bolt be used outdoors or in damp locations?
Yes. The Metallics JBLS41G is a galvanized steel lag bolt and is called out for use in corrosive environments, so exterior strut runs, damp mechanical rooms, and coastal work are within its intended use. Base material is steel per AISI 1006-1022.
2) How deep will a 5/16 x 1 inch lag bolt actually hold in wood?
The bolt is 1 inch long overall, measured below the hex head, so after you pass through a strap, clip, or hanger of any thickness you have very little thread left in the wood. For hanging conduit or pipe off a joist where you want real pull-out resistance, step up to a longer lag in the same series; the 1 inch length is for thin brackets going straight into solid wood. It is a full-bodied bolt with spaced threads and a gimlet point, so it starts in a pilot hole and draws itself in.
3) Does this hex lag bolt meet a dimensional standard I can put on a submittal?
Head and body dimensions conform to ASME B18.2.1-1996, and the steel is specified to AISI 1006-1022. Note for government and federally funded work: this item is not Buy American compliant and not ARRA compliant, with multiple countries of origin.
4) What size socket or wrench do I need for the JBLS41G lag bolt head?
Across the flats the hex head measures 0.484 to 0.500 inch, so a 1/2 inch socket or wrench is the right tool. Head height runs 0.195 to 0.235 inch.
5) What pilot hole should I drill for a 5/16 inch lag screw?
Shank outside diameter is 0.298 to 0.324 inch, which is the nominal 5/16. Drill the pilot to the thread root rather than the full shank so the 9 threads per inch get purchase, and keep the pilot smaller in softwood than in hardwood. Threads are right hand, so it drives clockwise.
6) Is this lag bolt strong enough for hanging conduit and pipe supports?
Tensile strength is 60,000 psi minimum with a hardness of Rockwell B70-B100, and the series is specified for the electrical, plumbing, heating and air conditioning trades. That covers conduit straps, channel, and pipe hangers into wood framing. It is a commercial-grade carbon steel lag, not a structural high-strength bolt.
7) How many lag bolts come in a jar of JBLS41G, and can I buy fewer?
They ship in a jar of 100, and the jar is the minimum order unit. Other sizes and quantities in the BLS and JBLS lag bolt series are available by request.
8) Do I need a washer with these lag bolts, or is one included?
No washers are packed with the jar. The spec lists a 0.125 in. washer OD reference for the series, so order washers separately if you are fastening through sheet metal, strap, or anything that could pull through under the hex head.
