Metallics JBLS51 – Frequently Asked Questions
1) What size lag bolt is the Metallics JBLS51, and what pilot hole does the 1/2 inch shank need?
The JBLS51 is a 1/2 x 5-1/2 inch hex head lag bolt. Measured across the threads the shank runs 0.482 to 0.515 inch, with 6 threads per inch, right hand. It is a full bodied bolt with spaced threads and a gimlet point, so it starts itself in wood once you have a pilot hole sized to the unthreaded body rather than the thread crest.
2) Can I use these zinc plated lag bolts outdoors or in a damp location?
No. The JBLS51 is a zinc plated steel lag bolt specified for use in wood in non-corrosive environments. Exterior exposure, coastal air, treated lumber or wet mechanical rooms will attack the plating. For those jobs use a hot dip galvanized or 18-8 stainless lag of the same 1/2 x 5-1/2 size instead.
3) Will a 1/2 inch lag bolt hold in concrete or block if I drill a hole first?
Not on its own. The JBLS51 is a wood lag with a gimlet point and spaced threads, intended for wood. Driven into masonry it has nothing to bite. For concrete or block you need a concrete screw or a wedge anchor sized for the load, not a lag bolt.
4) Can I use these lag bolts on a federally funded or Buy American job?
No. Metallics lists the JBLS51 as not Buy American compliant and not ARRA compliant, with multiple countries of origin. On a job with domestic sourcing requirements you need a lag bolt with a documented domestic origin instead.
5) What socket or wrench size fits the hex head on these 1/2 inch lag bolts?
The head measures 0.725 to 0.750 inch across the flats, which is a 3/4 inch socket or wrench. It is a standard hex head lag, so an impact driver with a 3/4 inch hex socket drives it.
6) How many bolts come in a jar, and can I get other lengths?
JBLS51 ships as a jar of 25, with 25 each as the order minimum. Metallics makes other sizes and quantities in the BLS and JBLS lag bolt series available by request if you need a different diameter, length or pack count.
7) Do these lag bolts meet a dimensional standard I can put on a submittal?
Yes. The JBLS51 lag bolt is built to ASME B18.2.1-1996 for dimensions, with material per AISI 1006 to 1022. Those two lines are what a spec reviewer or inspector is usually asking for on a fastener submittal.
8) Do I need washers with these hex lag bolts?
Lag bolts bear directly on the material, so a washer is normally used under the head to spread load on wood and keep the head from crushing the fiber. The JBLS51 ships as bolts only in the jar of 25, washers are not included, and the listed washer OD figure for the series is 0.156 in.
