Metallics QCSH30B – Frequently Asked Questions
1) What size hole do I drill for the Metallics QCSH30B 1/4 inch concrete screw?
The QCSH30B is a 1/4 inch diameter concrete screw, so it installs in a 3/16 inch hole drilled with a carbide bit, which is the standard pilot for 1/4 inch concrete screws. Drill the hole deeper than the embedment you need so dust has somewhere to go, then drive the screw with the 5/16 inch hex head.
2) How thick a fixture can I fasten with a 2-1/4 inch concrete screw?
At 2-1/4 inches overall, the QCSH30B leaves you roughly an inch of fixture thickness if you want a solid 1-1/4 inch minimum embedment into the concrete. For strut, conduit clamps, or panel feet that is plenty; for a thick base plate or a shimmed mount, step up to a longer screw so embedment is not sacrificed.
3) Do I need an anchor or shield with the Metallics Quadrive concrete screw?
No separate shield, sleeve, or plug is needed. The Quadrive screw cuts its own thread directly into the drilled hole in concrete, so the only thing you add is the drill bit and a driver. That also means it can be backed out and the hole reused in a different spot, unlike an expansion anchor.
4) How many concrete screws are in the Metallics QCSH30B box?
QCSH30B ships as a 1000 piece bulk box, and it is a single part number with no size or finish options to pick. That quantity suits electrical rough-in crews setting strut, box brackets, and clamp runs across a building rather than a one-off repair.
5) Can I use the 1/4 x 2-1/4 Quadrive screw in block or brick instead of poured concrete?
It is specified as a concrete screw, so poured concrete is the base material it is sold for. In hollow block or soft brick the thread engagement is far less predictable and the screw can spin out of the web, so for those substrates use an anchor rated for hollow masonry rather than this one.
6) What drives a 5/16 inch hex head concrete screw?
A 5/16 inch hex socket or nut driver on an impact driver or drill. The 5/16 inch head on the QCSH30B is the standard hex for 1/4 inch concrete screws, so a common magnetic 5/16 nutsetter seats it without a special bit.
7) What is the Metallics part number for the 1/4 x 2-1/4 hex head concrete screw?
Metallics QCSH30B. That number covers the 1/4 inch diameter by 2-1/4 inch Quadrive concrete screw with the 5/16 inch hex head, US made, packed 1000 to the box. Order by that MPN to avoid landing on a slotted or Phillips flat head version.
