Metallics CSF30SS – Frequently Asked Questions
1) Do I need an expansion shield or anchor sleeve with these 1/4 inch concrete screws?
No sleeve, shield, or plug is needed. The CSF30SS is a one-piece concrete screw anchor that threads directly into a drilled hole in concrete or masonry, which is why electricians use this type instead of a two-part expansion anchor when they are setting strut, straps, or enclosures on block and slab.
2) What drill bit do I use for a 1/4 inch concrete screw anchor like the CSF30SS?
A 1/4 inch concrete screw takes a 3/16 inch carbide hammer-drill bit. Drill the hole deeper than the embedment you want so dust has somewhere to go, blow it clear, then drive the screw with a Phillips bit. Hole diameter is what controls holding power on this style of anchor, so do not oversize it.
3) Will a 2-1/4 inch concrete screw be long enough for mounting strut or a conduit strap to block?
At 2-1/4 inches overall, the CSF30SS gives you room to pass through the thickness of a strut channel, clamp, or box flange and still get a usable embedment into the concrete or block behind it. Add your fixture thickness to the embedment you need and check it comes in under 2-1/4 inches; thin sheet-metal straps and standard strut leave plenty.
4) Why choose a flat head Phillips anchor instead of a hex head concrete screw?
Flat head is the one to use when the fastener has to sit flush or close to it, for example through a countersunk hole in a plate or where a cover, trim, or another component passes over the head. A hex washer head sits proud and needs a driver socket; the CSF30SS drives with a standard Phillips bit, which is usually already in the drill.
5) What is the Metallics part number for the 1/4 x 2-1/4 flat head concrete screw anchor?
Order it as Metallics CSF30SS. That number covers the 1/4 x 2-1/4 inch flat head Phillips concrete screw anchor in the 100-piece pack, which is how distributors and counter staff will look it up.
