Metallics QCSH20B – Frequently Asked Questions
1) What driver do I need for the Metallics Quadrive concrete screw?
The head is a 5/16 inch hex, so it drives with a 5/16 inch hex socket or magnetic nutsetter in an impact driver or drill. No Phillips or star bit is involved. Keep a spare nutsetter on the truck if you are setting a full 1,000-piece box in one go.
2) What size hole do I drill for a 1/4 inch Quadrive concrete screw?
A 1/4 inch concrete screw is matched to a 3/16 inch carbide bit, and the hole should be drilled deeper than the screw will reach so the dust has somewhere to go. Hole quality decides holding power here more than anything else: a worn bit opens the hole oversize and the threads lose their bite.
3) Can I reuse or back out a Quadrive concrete screw if I need to move the strap?
It backs out with the same 5/16 inch nutsetter, which is the main reason crews prefer a concrete screw over a drop-in or sleeve anchor when a layout might shift. Re-driving into the same hole is not reliable though, since the original threads are already cut in the concrete. Move over and drill fresh.
4) Is a 1,000-piece box of QCSH20B a jobsite quantity or a shelf stock item?
It is a bulk box, 1,000 pieces of the single 1/4 x 1-3/4 size, which is how electrical contractors and MRO storerooms buy their most-used anchor. If you only need one length occasionally, a bulk box of one size is overkill; it pays off when 1/4 x 1-3/4 is your standard for conduit and strut mounting across a building.
