Metallics JALS15 – Frequently Asked Questions
1) Can the Metallics JALS15 lag screw be used in concrete or steel deck?
No. The JALS15 is a wood lag screw, so it needs wood joists, blocking, or framing to bite into. For concrete overhead you need a drop-in or wedge anchor with a rod hanger, and for steel bar joist or deck you need a beam clamp or deck hanger.
2) What is an acoustical lag screw used for on a ceiling job?
Acoustical lag screws like the Metallics JALS15 are driven into wood joists or blocking overhead to carry suspended ceiling grid hanger wire, and they also serve as anchor points for threaded rod or chain hanging conduit, boxes, and fixtures. The 4 inch length gives enough embedment to reach solid wood through furring or an existing ceiling layer.
3) Does the zinc plating on the Metallics JALS15 hold up outdoors?
It is a steel screw with a zinc plating, which is a general indoor corrosion finish. For ceiling work, interior conduit support, and dry MRO use it is fine. For exterior, wet, or corrosive locations, specify a hot dip galvanized or stainless lag instead.
4) Do I need to pre-drill for a 1/4 inch by 4 inch lag screw?
In solid wood framing a pilot hole is standard practice for a 1/4 inch lag of this length, and it prevents splitting of joists and blocking. Drive it with a nut driver or wrench on the hex head rather than an impact set too high.
