How far apart should these be spaced?

Just finishing a 12 x 12 room in my lower leverl with 8' ceilings. WOndering how far apart these anchors should be spaced? Is every 16" to much?
Asked by: Kelmey
Hi Kelmey, Great question, the minimum anchor spacing for 1/4" Tapcons is four inches. Spacing the anchors farther apart than four inches should not affect the performance. Please contact our Technical Support Team for additional information. They are available at 800-726-7386 from 8:30 - 4:30 CT Monday - Friday.

Do Tapcons with even more corrosion resistance exist for outdoor Florida pool enclosure applications?

Existing Tapcons corrode above the concrete and the heads snap off over a number of years. Wonder if stronger, more corrosion resistance is available? Also wonder about recommended length into the concrete?
Asked by: Fpassa
Tapcon Stainless Steel Concrete Anchors provide superior corrosion resistance and are recommended for pool enclosure applications. Stainless Steel Tapcon is available in many Home Depot stores in Florida. Check you local store for availability. The recommended embedment depth for Tapcon anchors is 1 - 1-3/4 in., depending on the diameter and length of the anchor. For additional information, please contact CCNA Technical Support at 800-726-7386.

Customer Reviews

1/4 in. x 3-1/4 in. Hex-Washer-Head Concrete Anchors (75-Pack) is rated 4.5 out of 5 by 2.
Rated 4 out of 5 by from Works great, except for the anchor's socket size The anchors were easy to use. The only drawback is the head size. The socket called for in the directions didn't fit at all. The screws are so tough that I turned out the metric socket I ended up using. I'll use them again, but be sure to buy a new socket or 2 for any major project.
