Metallics QCSH40 – Frequently Asked Questions
1) What driver or socket do I need to install the QCSH40 anchor?
It takes a 5/16 inch hex driver. The QCSH40 has a 5/16 inch hex head, so an impact driver with a 5/16 nut setter or a 5/16 socket drives it. No separate sleeve or expansion shield to set first, the screw cuts its own thread in the concrete.
2) Can I use a 1/4 x 2-3/4 concrete screw to mount strut, conduit straps, and boxes to a concrete wall?
That is the normal use for the QCSH40. A 1/4 inch by 2-3/4 inch concrete screw gives enough length to pass through strut, a one-hole strap, or a box bracket and still get working embedment into concrete or block. For thin fixtures against the slab, the extra length is wasted and a shorter screw of the same diameter is the cleaner choice.
3) Is the QCSH40 anchor removable, or is it permanent like a wedge anchor?
It backs out. A concrete screw like the QCSH40 threads into the hole and can be unthreaded with the same 5/16 hex driver, which makes it the right pick for temporary mounts, fixtures you expect to relocate, or anything you may need to service. A wedge or sleeve anchor expands in the hole and is effectively permanent once set.
4) Is the QCSH40 concrete screw okay for outdoor or damp locations?
The QCSH40 is steel with a zinc finish. Zinc plating handles dry interior work and incidental moisture, but it is not a stainless or hot dip coating, so for sustained exterior exposure, wet locations, or treated lumber contact you want a stainless or heavier coated anchor instead.
5) How many Metallics QCSH40 anchors come in a jar?
100 pieces per jar. The QCSH40 ships as a jar pack of 100 of the 1/4 x 2-3/4 concrete screws, which is the practical count for a crew setting strut or straps through a run rather than a one-off repair.
6) What is the Metallics part number for the 1/4 x 2-3/4 zinc concrete screw with a 5/16 hex head?
QCSH40. That is the Metallics MPN for the 1/4 inch by 2-3/4 inch quick drive concrete screw, 5/16 inch hex head, steel with zinc plating, sold 100 to a jar.
