Metallics QCSH2B – Frequently Asked Questions
1) What driver do I need for the Metallics QCSH2B Quadrive concrete screw?
It drives with a 1/4 inch hex socket or nut setter in an impact driver, since the QCSH2B has a 1/4 inch hex head. The Quadrive thread form is designed to cut its own threads in the masonry, so the screw is installed directly into a pre-drilled hole with no plastic plug or expansion sleeve.
2) Can I use the Metallics QCSH2B in block or brick, or only poured concrete?
Concrete screws of this type work in poured concrete, solid brick, and the solid webbing of CMU block. They should not be driven into hollow block cells, drywall, or soft mortar joints, where the cut thread has nothing to grip. For hollow-wall work use a toggle or sleeve-type anchor instead of a 3/16 inch concrete screw.
3) Do I need a separate anchor or shield with the Quadrive concrete screw?
No. The QCSH2B is a one-piece masonry screw anchor, so there is no shield, sleeve, or plug to set first. Drill, clean the hole, drive the screw. That also means it can be backed out and the fixture removed without destroying the hole, which is why these get used for temporary bracing and for equipment that gets serviced.
4) Is the Metallics QCSH2B sold in smaller quantities than 1000?
The QCSH2B is a 1000 piece bulk box of 3/16 x 1-3/4 inch concrete screws, which is how electrical and MRO stockrooms usually buy this size for conduit and box mounting. If you need a smaller count, look for the same diameter and length in a jar or contractor pack rather than the bulk carton.
