Metallics JBLS48 – Frequently Asked Questions
1) What size and thread does the Metallics JBLS48 lag bolt have?
The JBLS48 is a 3/8 x 4-1/2 inch hex head lag bolt with 7 threads per inch, right hand thread. Shank diameter measures 0.360 to 0.388 inch across the unthreaded body, and overall length is 4.5 inches. Threads are the spaced, coarse lag type with a gimlet point for driving into wood.
2) Can I use these zinc lag bolts outdoors or in a damp location?
No. Metallics specifies the zinc plated steel JBLS lag bolt for use in wood in non-corrosive environments only. Zinc plating is a mild indoor/dry-location finish, so for exterior framing, pressure treated lumber, or wet and coastal work you want hot dip galvanized or 18-8 stainless lags instead.
3) How strong are these lag bolts, and is there a published standard behind them?
The JBLS48 is made to ASME B18.2.1-1996 dimensionally, from AISI 1006 to 1022 steel, with 60,000 psi minimum tensile strength and a hardness of Rockwell B70 to B100. That is standard commercial low-carbon lag screw material, suitable for general anchoring into wood framing, not a high-strength structural bolt substitute.
4) Are Metallics JBLS48 lag bolts Buy American or ARRA compliant for a government job?
No. The JBLS48 is not Buy American compliant and is not ARRA compliant; country of origin is listed as multiple. If your spec carries a domestic sourcing requirement, this part will not clear it.
5) What jobs are Metallics JBLS lag bolts intended for?
Metallics lists the BLS and JBLS lag bolts for the electrical, plumbing, heating and air conditioning trades, which is where they get used most: lagging strut, pipe hangers, unistrut, panel backboards, and equipment supports into wood joists, studs, and blocking. The 4-1/2 inch length gives enough embedment to reach through furring or a backer board and still bite framing.
6) Is the part number JBLS48 the same bolt as the BLS version?
JBLS48 is the jar-packed 3/8 x 4-1/2 zinc plated hex lag, part of Metallics' combined BLS and JBLS lag bolt series. The J prefix denotes the jar pack of 50; the bolt itself is the same full-bodied hex head lag with spaced threads and a gimlet point. Order by JBLS48 if you want the jar.
