How do you anchor into concrete?
Simply drill a hole into the concrete, hold the fixture you’re fastening over the hole, then use a hammer to tap the anchor into the hole. As you drive in the pin, the sleeve expands outward, trapping the anchor in the hole.
How deep do concrete anchors need to be?
Steps to Installing Concrete Fasteners
The hole should be drilled 1/4″ to 1/2″ deeper into the base material than the anchor will penetrate. This allows for any material to fall when the anchor is inserted into the hole. After the hole is drilled, it must be cleaned of all debris, material or dust.
What are the best concrete anchors?
Wedge Anchors are extremely popular and are one of the strongest anchors for hold strength. Wedge anchors look and function like a sleeve anchor but have a much smaller sleeve near the bottom of the anchor.
How many anchor bolts do I need?
There must be an anchor bolt within 12 inches of each end. And the maximum spacing between any bolts on a single bottom plate is 6 feet. I put my anchor bolts six inches from the end of each bottom plate. Thus a (8 to 12) foot bottom plate would need three (3) anchor bolts.

Can I use plastic anchors in concrete?
Once you anchor hammer-set fasteners, there’s no easy way to remove them without destroying the material or the fastener. If the fastener works loose, leave it in place and drill another hole. Don’t use hammer-set fasteners in crumbly concrete or mortar. Use a plastic anchor instead.
Do I need to pre drill for concrete screws?
Each diameter of concrete screw has a specific diameter carbide drill bit that must be used for installation. The 3/16” diameter screw requires a 5/32” hole and the 1/4” requires a 3/16” hole. The hole must be drilled using a hammer drill with a carbide tipped bit meeting ANSI standards.
