Metallics QCSH40B – Frequently Asked Questions
1) What drive or bit do I need for a Metallics Quadrive concrete screw?
The QCSH40B is a Quadrive concrete screw with a 5/16 inch head, so it drives with a 5/16 inch hex socket or nut driver in an impact driver. No separate plug, shield, or expansion sleeve is involved, it threads directly into the drilled hole.
2) How many concrete screws come in a box of Metallics QCSH40B?
The QCSH40B ships 1000 pieces per box. That is a bulk quantity aimed at crews running repetitive anchoring, strut, conduit clamps, pipe hangers, electrical boxes, rather than a small count for a one-off repair.
3) Should I use a 1/4 inch concrete screw or a wedge anchor for fastening into concrete?
A screw anchor like the 1/4 x 2-3/4 QCSH40B threads into a drilled hole and can be backed out and the fixture repositioned, which suits conduit straps, strut, hangers, and light brackets, and it works in overhead and shallow-base-material situations where you do not want expansion force. A wedge anchor is a one-way, non-removable mechanical expansion anchor and is the usual choice for higher-load structural attachment. For electrical rough-in and MRO hanging work, the screw anchor is normally what goes in the bucket.
4) What size hole do I drill for a 1/4 inch Quadrive concrete screw?
A 1/4 inch diameter concrete screw such as the QCSH40B is installed in a hole drilled with a carbide hammer bit matched to the screw diameter, and the hole must be drilled deeper than the screw's embedment so dust has somewhere to go. Blow or vacuum the hole clean before driving, since packed dust is the most common reason these spin out or snap.
