Metallics LCS3824 – Frequently Asked Questions
1) Do I need an expansion shield or sleeve to install a 3/8 inch concrete screw anchor?
No. A concrete screw anchor like the LCS3824 threads directly into a drilled hole in concrete, so there is no shield, sleeve, or wedge to set. You drill, blow the hole clean, and drive the screw with the hex head. That also means it can be removed and the hole reused for repair work, which a wedge anchor will not allow.
2) What are 3/8 inch large-diameter concrete screws used for on electrical jobs?
They are the workhorse fastener for anchoring into concrete and block: strut channel and trapeze hangers, panelboard and enclosure backs, cable tray supports, transformer and equipment bases. Metallics catalogues the LCS3824 in its electrical fastener line, and a jar of 50 covers a typical run of hanger points.
3) Is a zinc plated concrete screw anchor OK outdoors or in a wet location?
Zinc plating, which is what the LCS3824 carries, is a dry interior finish. It handles damp construction exposure during a build, but for permanent exterior, coastal, or continuously wet locations you want a stainless or heavy mechanically galvanized concrete screw instead. Standing water and chlorides will take zinc plating off.
4) Can I use the LCS3824 in hollow block or brick, not just poured concrete?
Concrete screws of this type are intended for solid base material. In hollow CMU you can only land in the face shell or a grouted cell, which cuts holding value sharply, and in brick you must stay out of the mortar joint. For a hollow wall where you need real pull-out resistance, a toggle or a sleeve-type anchor sized for hollow block is the better choice.
5) What tool drives the hex head on the Metallics LCS3824?
A hex socket on an impact wrench or impact driver. The LCS3824 is a hex head screw, so there is no bit to cam out, and an impact driver will seat 50 of them quickly. Drive to snug against the fixture; overdriving can strip the threads cut in the concrete.
