Metallics CSF1F – Frequently Asked Questions
1) What size hole do I drill for a 3/16 inch concrete screw?
A 3/16 inch concrete screw like the CSF1F is installed in a 5/32 inch carbide hole, drilled deeper than the embedment so dust has somewhere to go. At 1-1/4 inches overall length, subtract the thickness of whatever you're fastening to see how much thread is left in the concrete, so thin straps and plates get good embedment while a thick bracket may call for a longer screw.
2) Is the CSF1F the right fastener for drywall or hollow block?
No. The CSF1F cuts its own thread in solid masonry, so it needs concrete, solid brick, or the solid web of a block. In drywall or the hollow cell of a block it has nothing to bite and will spin out; use a toggle or a hollow-wall anchor there instead.
3) How many anchors come in a jar of Metallics CSF1F?
100 screws per jar. Metallics packages the CSF1F in a jar rather than a box, which keeps the count intact on a service truck and makes it easy to scoop a handful for a strap or box run.
4) Why choose a flat head concrete screw instead of a hex head for mounting electrical boxes and straps?
The flat head Phillips on the CSF1F sits flush or countersunk, so it won't hold a device box, strut, or conduit strap off the wall the way a hex washer head does. Pick hex head when you want a driving surface and don't care about profile; pick this flat head Phillips when the fastened part has a countersunk hole or must lie flat against the concrete.
5) Do I need a special driver for Metallics CSF1F anchors?
No separate setting tool. The CSF1F drives with a standard Phillips bit in a drill or impact driver, so the whole install is drill the 5/32 inch hole, blow it clear, and drive the screw. That is the main reason crews choose a concrete screw over a drop-in or sleeve anchor on repetitive strap and box work.
6) Are Metallics CSF1F concrete screws suitable for outdoor or damp locations?
The CSF1F is zinc-plated steel with a blue coating, which handles interior and ordinarily dry exterior-protected work. For continuously wet, coastal, or corrosive locations, specify a stainless concrete screw instead; plated steel will eventually rust in standing moisture.
7) Can I reuse the same hole if I back a CSF1F concrete screw out?
You can remove and reinstall the same 3/16 inch screw in the same hole once, but the cut threads in the concrete wear fast. For anything carrying load, or a fixture you expect to service repeatedly, drill a fresh hole or move to a mechanical anchor with a reusable female thread.
