Metallics JBLS6 – Frequently Asked Questions

1) How many 1/4 x 4 inch Metallics hex lag bolts come in a jar, and can I buy fewer?
The Metallics JBLS6 lag bolt ships in a jar with a 100 piece minimum, so 100 is the smallest quantity that moves. For a crew stocking a van or a maintenance shop restocking a fastener bin, that jar is the buy unit. Full jar weight is listed at 2077 g.
2) Will a zinc plated lag bolt hold up outdoors or in a damp mechanical room?
Zinc finish on carbon steel is meant for non-corrosive service. It handles the humidity of an interior mechanical room, a crawlspace, or a garage, but it is not the fastener for coastal exposure, pressure treated lumber in wet contact, or pool and wash down areas. For those, move to a stainless or hot dip galvanized lag of the same 1/4 x 4 size.
3) Does this Metallics lag bolt meet a dimensional standard for spec submittals?
Dimensions conform to ASME B18.2.1-1996, and the steel is to the AISI 1006-1022 material standard. Those two are what a submittal reviewer on an institutional or government job typically wants to see on a lag bolt line item. Note it is listed as not Buy American compliant and not ARRA compliant, with multiple countries of origin, so on a federally funded project with domestic sourcing requirements this will not qualify.
4) Is this lag bolt strong enough for hanging electrical panels and conduit supports on wood framing?
That is the intended use. Minimum tensile strength is 60,000 psi with a Rockwell B70-B100 hardness, and the field application listed covers electrical, plumbing, heating and air conditioning work. Electricians use the 1/4 x 4 for panel backing, strut and conduit hanger attachment, and equipment brackets into studs or blocking. Pull out capacity depends on the wood species and embedment depth, so the engineer's detail governs on anything load rated.
5) What thread does this lag bolt have, and is it a wood screw thread or machine thread for a nut?
It is a wood thread, not a machine thread. Spaced threads at 10 per inch, right hand direction, with a gimlet point that drives into timber. You cannot run a 1/4-20 nut onto it, so it is not a substitute for a hex cap screw through metal. Use it where the fastener threads into wood and seats against the surface.
6) Do I need a washer with this lag bolt, and does one come in the jar?
Nothing but bolts is in the jar, washers are ordered separately. A flat washer under the head is normal practice on lag bolts so the head does not crush into the wood and so you get even bearing when you torque it. The listed washer OD reference is 0.094 inches.
7) Can I drive this lag bolt with an impact driver or do I need to hand torque it?
An impact or a socket on a drill works, and most contractors run them that way, but the warning in the install sequence matters: tighten to the required torque and stop. Over driving a 1/4 inch lag strips the wood threads or splits the member, and once the hole is stripped the connection is gone. Seat the head flat against the surface and back off.
