Metallics JBLS14G – Frequently Asked Questions
1) What size lag bolt is the Metallics JBLS14G, and how many come in a jar?
It's a 5/16 x 3 inch hex head lag bolt, galvanized, sold 100 to a jar. The order minimum is 100 count, so a jar is the smallest buy. Measured shank outside diameter runs 0.298 to 0.324 inch and the overall fastener length is 3 inches.
2) Can these galvanized lag bolts be used outdoors or in damp locations?
Yes. The galvanized finish on the JBLS14G is specified for use in corrosive environments, which covers exterior strut runs, damp mechanical rooms, and coastal or wash-down areas. The base material is steel, so the zinc coating is what carries the corrosion protection; avoid grinding or cutting the bolt, since that exposes bare steel.
3) Do I need to drill a pilot hole for these lag bolts, or do they self-start?
The JBLS14G has a gimlet point, so it will start itself in soft wood. For a 5/16 inch lag in dimensional lumber, engineered lumber, or anything dense, drill a pilot hole anyway. The threads are spaced at 9 threads per inch across a 0.298 to 0.324 inch shank, and without a pilot you risk splitting the member or snapping the bolt before it seats.
4) What size wrench or socket do I need for a 5/16 inch hex lag bolt?
The hex head across-flats width on the JBLS14G measures 0.484 to 0.500 inch, so a 1/2 inch socket or wrench fits it. Across corners it runs 0.552 to 0.577 inch, which matters if you're driving in a tight channel or near a wall where socket clearance is thin.
5) Will these Metallics lag bolts meet a Buy American requirement on a federal job?
The JBLS14G is flagged as both ARRA compliant and Buy American compliant in the manufacturer's data. Country of origin is China. For a federally funded project, pass both of those facts to your spec reviewer, since the compliance basis differs by program and by contract clause.
6) What standard and strength do these hex lag bolts meet?
Dimensions follow ASME B18.2.1-1996, the material is drawn from AISI 1006 to 1022 steel, minimum tensile strength is 60,000 psi, and hardness runs Rockwell B70 to B100. That's the data a submittal reviewer typically wants on a 5/16 lag.
7) Should I add washers when installing these lag bolts?
Yes, for most strut, strap, and plate work. A hex lag head bears on a small footprint, and a flat washer spreads the load and keeps the head from crushing into wood. Order washers separately in a matching galvanized finish so you don't set up dissimilar-metal corrosion on an exterior run.
8) I need a different length or a stainless version of this lag bolt. Is that available?
The Metallics BLS and JBLS series runs other sizes and quantities by request, so a different diameter, length, or jar count can be sourced within the same family. The JBLS14G itself is the galvanized steel 5/16 x 3.
9) How much does a jar of 100 of these 5/16 x 3 lag bolts weigh?
A jar comes in at 5.63 lbs, with the shipping carton measuring 4.5 by 4.5 by 7.25 inches. Useful if you're loading a van with several jars across multiple sizes or estimating a shelf for MRO stock.
