Metallics JBLS5 – Frequently Asked Questions
1) What size lag bolt is the Metallics JBLS5, and how many come in a jar?
The JBLS5 is a 1/4 inch by 3-1/2 inch hex head lag bolt in zinc plated steel, sold 100 to a jar. The jar is the minimum order quantity, so one jar is the smallest purchase.
2) Can I use these zinc lag bolts outdoors or in a damp location?
No. These zinc plated steel lag screws are specified for use in wood in non-corrosive environments. For exterior, damp, or chemically aggressive locations you want hot dip galvanized or 18-8 stainless lags instead.
3) Are these Metallics lag bolts Buy American or ARRA compliant for a government job?
No. The JBLS5 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. If your project carries a domestic sourcing requirement, these will not satisfy it.
4) What size pilot hole and drill bit should I use for a 1/4 inch lag screw into wood?
Measure off the shank, not the thread. The JBLS5 runs an outside diameter of 0.237 to 0.260 inch with 10 threads per inch and a gimlet point, so in softwood a 5/32 inch pilot and in hardwood a 3/16 inch pilot gives the threads wood to bite while keeping the bolt from splitting the member. The gimlet point starts the hole, so no lead hole is needed in soft material for short penetrations.
5) How strong are these lag bolts, and what are they rated to?
Low carbon steel lag screws with a 60,000 psi minimum tensile strength and a hardness of Rockwell B70 to B100, made from AISI 1006 to 1022 steel. Dimensionally they conform to ASME B18.2.1-1996. That is standard commercial lag screw strength for anchoring into wood framing, not a structural Grade 5 or Grade 8 bolt.
6) Is this a full-body lag screw or a reduced shank?
Full bodied, with a hex head, spaced threads and a gimlet point. The unthreaded shank runs full diameter, so the bolt bears on the shank in the clamped part and the threads engage only the wood below.
7) Are the threads right hand, and will a standard 1/4-20 nut thread onto these?
Threads are right hand, driven clockwise. But these are lag screw threads at 10 threads per inch with a gimlet point, not machine threads, so a 1/4-20 nut will not run on. A lag screw threads directly into wood and takes no nut.
8) Do I need washers with these lag bolts, and are any included?
The jar holds lag bolts only, no washers. For most hanger and strap work a flat washer under the hex head is good practice so the head does not crush into soft wood; order 1/4 inch flat washers separately. Metallics offers other sizes and quantities in the BLS and JBLS lag bolt series on request if you need a different length or diameter.
