Metallics JBLS16 – Frequently Asked Questions
1) What size pilot hole and socket do I need for a Metallics JBLS16 5/16 x 4 lag bolt?
The JBLS16 lag screw measures 0.298 to 0.324 inch across the shank outside diameter with 9 threads per inch, right hand. Drive it with a 1/2 inch socket or wrench: the hex head measures 0.484 to 0.500 inch across the flats. Lag screws this size want a pilot hole drilled in the wood, sized just under the shank diameter in the threaded portion so the threads cut rather than split the member.
2) Can I use these zinc plated lag bolts outdoors or in a damp mechanical room?
No. The JBLS16 is steel with a zinc finish and is specified for use in wood in non-corrosive environments. Zinc plating handles dry interior work, but for exterior, wet, or treated-lumber contact you want hot dip galvanized or 18-8 stainless lags instead, since zinc plating will corrode and treated lumber chemistry attacks it.
3) Will a 4 inch lag screw hold strut or pipe hangers into wood joists?
Yes, that is the intended use. The 5/16 x 4 inch hex lag is listed for the electrical, plumbing, heating and air conditioning trades, and the 4 inch length gives you enough embedment through a hanger or strut back plate into solid framing. It is a full-bodied bolt with a hex head, spaced threads and a gimlet point, so it starts into wood without a nut or anchor behind it.
4) Is the Metallics JBLS16 lag bolt Buy American or ARRA compliant for a government job?
No on both counts. The JBLS16 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project carries domestic sourcing requirements, this part will not satisfy them.
5) How many lag bolts come in a jar and what is the minimum order?
These 5/16 x 4 hex lags are packaged 50 to a jar, and the order minimum is 50 each, so one jar is a full order. Metallics notes other sizes and quantities are available by request.
6) What strength and standard do these Metallics lag screws meet for a submittal?
The JBLS16 is made to ASME B18.2.1-1996 dimensionally, from AISI 1006-1022 steel, with 60,000 psi minimum tensile strength and Rockwell B70-B100 hardness. That is the standard low-carbon lag screw spec, which is what most wood-framing hanger submittals call for.
7) Can I use a lag screw like this into concrete or masonry?
No. The JBLS16 is a wood lag screw, specified for use in wood, with a gimlet point and spaced threads that cut into timber. Concrete and block call for a screw anchor or a sleeve/wedge anchor rated for masonry instead. Driving a wood lag into a plastic shield in concrete is not an equivalent of a rated anchor.
