CONFAST CSH38134 – Frequently Asked Questions

1) What sizes do CONFAST hex head concrete screws come in?
Seven sizes are offered in the CONFAST CSH hex head line: 3/8" x 1-3/4", 3/8" x 2-1/2", 3/8" x 3", 3/8" x 4", 3/8" x 5", 1/2" x 3" and 1/2" x 4". Diameter drives the anchor's holding capacity, length drives embedment plus the thickness of whatever you are fastening down, so pick length as fixture thickness plus the embedment you want in the concrete.
2) Will CONFAST concrete screws work in block, or only in poured concrete?
Both. The CSH hex head screw is sized for direct fastening into concrete, block, and other masonry substrates, so hollow or solid CMU walls are in scope alongside slabs and poured walls. In hollow block, land the anchor in the web or a filled cell rather than the face shell.
3) Do I need an anchor or shield with a CONFAST hex head concrete screw?
No sleeve, shield, or plug is needed. These are direct-to-concrete screw anchors, meaning the screw cuts its own threads in a pre-drilled hole in the base material. That also makes them removable, which is why maintenance crews favor them over expansion anchors for temporary or re-serviceable mounts.
4) How many screws are in a box of CONFAST CSH concrete screws?
25 per box. That is a job-lot quantity rather than a bulk carton, so for a facility maintenance cart or a single equipment-mounting run one box usually covers it; for a large anchoring layout, count your holes first and order multiple boxes of the same size so the fastener is identical across the run.
5) Can I drive CONFAST hex head concrete screws with an impact driver, or do I need a wrench?
The hex head takes a standard wrench, socket, or hex driver, so an impact wrench with the matching socket is the normal way contractors run them. There is no recess to cam out of, which is why hex head is the usual pick over a flat or Phillips head on 3/8" and 1/2" diameter anchoring work.
6) Which length CONFAST concrete screw should I use for mounting strut or conduit clamps to a concrete wall?
For thin fixtures like a strut channel foot or a one-hole conduit clamp, the shorter 3/8" x 1-3/4" or 3/8" x 2-1/2" sizes are the usual call, since you only need the fixture thickness plus embedment. Step up to 3/8" x 4" or 5" when you are going through furring, sleepers, or a thick base plate. The 1/2" x 3" and 1/2" x 4" sizes are there for heavier equipment bases where you want the larger diameter.
7) Is the same CONFAST CSH screw available again for a later phase of the job?
Yes, the CSH hex head screw is stocked in consistent sizing box after box, so a property manager or GC standardizing on one fastener can reorder the identical 3/8" x 2-1/2" (or whichever size was used) for later phases and recurring maintenance without a spec change.
