Metallics QCSH2 – Frequently Asked Questions
1) What size hole do I drill for a 3/16 inch concrete screw?
A 3/16 inch diameter concrete screw like the Metallics QCSH2 is installed in a 5/32 inch hole drilled with a carbide bit. Drill the hole deeper than the embedment you need so cuttings have somewhere to go, then drive the screw without hammering it.
2) Do I need a special bit to drive the Metallics Quadrive concrete screw?
No special driver bit is needed. The QCSH2 has a 1/4 inch head, so it drives with a standard 1/4 inch hex driver or socket in an impact or drill. The Quadrive head also accepts a square drive, which is handy when you're working overhead and want the bit to hold the screw.
3) Will a concrete screw hold in hollow block, or do I need a different anchor?
A 3/16 inch self-tapping concrete screw works in solid concrete, brick, and the solid webs of block. In the hollow cell of a block it has nothing to thread into, so hit the mortar joint or a web, or switch to a toggle or sleeve-type anchor for the void.
4) Is the Metallics QCSH2 anchor made in the USA?
Yes, the 3/16 x 1-3/4 Quadrive concrete screw from Metallics is US made, which matters on government, school, and other Buy American jobs where domestic fasteners are called out on the submittal.
5) Can concrete screws be removed and reused?
They back out cleanly, which is the main reason crews use them over drop-in anchors for temporary bracing and layout work. Reusing the same hole is not recommended though, because the thread the screw cut is already formed; move over and drill fresh for full holding value.
