Metallics CSH20FM – Frequently Asked Questions
1) What hole size do I drill for a 1/4 inch concrete screw anchor?
A 1/4 inch concrete screw like the CSH20FM is set in a 3/16 inch carbide bit hole, drilled deeper than the embedment so dust can clear. Blow or vacuum the hole out before driving, then run the screw in without overtightening.
2) How many anchors come in a box of Metallics CSH20FM?
One box holds 1000 pieces. That is the pack as sold, so it suits crews setting strut, conduit clamps, and device boxes in volume rather than a one-off repair.
3) What driver do I need for a 5/16 hex head concrete screw?
A 5/16 inch hex socket or magnetic nut setter in an impact driver. The CSH20FM has a hex washer head sized 5/16 across the flats, and the head is slotted as well if you need a screwdriver as a backup.
4) Do I need an anchor shield or plastic plug with these Metallics screws?
No. A concrete screw of this type cuts its own thread in the drilled hole, so there is no shield, sleeve, or plastic plug to insert. Drill, clean the hole, drive the screw. That also means it can be removed and the fixture repositioned, unlike a wedge or drop-in anchor.
5) Is the blue coating on the CSH20FM anchor suitable for damp locations?
The CSH20FM carries a blue steel-zinc coating, which is a corrosion-resistant plating typical of interior and protected exterior concrete screws. For continuously wet, coastal, or chemically aggressive settings, specify a stainless concrete screw instead.
6) What electrical work are these 1/4 inch Metallics anchors used for?
They are a general-purpose fastener for electrical rough-in: mounting strut and channel, conduit straps and clamps, pull boxes, panel backing, and device boxes to concrete or block. Metallics files them in its electrical fastener range, and the 1000-piece box reflects the repetitive nature of that work.
