What size hole do I drill for a 5/16 concrete anchor?
Drill the hole a 1/2″ deeper than the anchor will penetrate the concrete, making sure the minimum embedment requirements of 1-1/8″ is met. The hole can be drilled while the fixture is in place. The minimum hole in the fixture for the 5/16″ x 3-1/2″ Wedge Anchor Zinc Plated is 7/16″.
How deep should wedge anchor be in concrete?
A 5/8” concrete wedge anchor requires a 5/8” hole to be drilled into the concrete. The hole in the concrete needs to be drilled a minimum of 1/2” deeper than the concrete wedge anchor will penetrate into the concrete.
How long should concrete wedge anchors be?
As a rule of thumb, the space for the nut and washer is equal to the diameter of the wedge anchor being used. For example, if a 2×4 is being fastened to concrete with a 1/2” wedge anchor then the minimum length of wedge anchor would be 1-1/2”(2×4) + 2-1/4”(minimum embedment) + 1/2”(space for nut and washer) = 4-1/4”.
Are wedge anchors better than Tapcons?
Tapcon and wedge anchors are pre-installed mechanical anchors that attach structural objects to concrete structures. However, the wedge anchor suits heavier-duty applications, vs the Tapcon anchor that typically serve lighter deployments. Another difference between them is in their fastening method.
What size drill bit do I use for a 5/16 Tapcon?
The 3/16” tapcon uses a 5/32” bit, the 1/4” tapcon needs a 3/16” diameter bit, the 3/8” tapcon requires a 5/16”, the 1/2” tapcon requires a 7/16” bit, a 5/8”tapcon needs a 1/2” bit and the 3/4” tapcon requires the use of a 5/8” carbide tipped bit.
How much weight can a 1/2 wedge anchor hold?
Technical Specifications for Wedge Anchors
| Size | Minimum Embedment | Pull-Out (lbs.) |

| 3/8” | 1-1/2” | 1223 |
| 1/2” | 2-1/4” | 2999 |
| 5/8” | 2-3/4” | 3749 |
How strong are concrete wedge anchors?
Wedge Anchor Holding Values The holding power of the wedge anchor, as with any anchor, is always dependent on the quality of the concrete. As a rule of thumb, a safety factor of 4:1 or 25%, is generally accepted as a safe working load.
What size drill bit do you use for a 5/16 Tapcon?
How much weight can wedge anchors hold?
What is the strongest anchor for concrete?
Wedge anchors
Wedge anchors are typically the strongest anchors, but not every application requires a heavy-duty anchor. Some will do just fine with a plastic wall anchor or a nail-in version.
Do you need a hammer drill for Tapcon screws?
The hole must be drilled using a hammer drill with a carbide tipped bit meeting ANSI standards. A bit that meets ANSI standards will ensure that the hole diameter will meet the requirements of the Tapcon®.
How far apart should Tapcon screws be placed?
First, the minimum recommended distance between any two anchors is 10x the anchor diameter (2 1/2 inches for 1/4 inch anchors), at the risk of weakening the holding strength of each.
How to install concrete wedge anchors?
Determine the minimum length of wedge anchor to use by adding the thickness of the material to be fastened to the minimum embedment for the diameter of the anchor to
How do you install a wedge anchor?
– Using the hammer drill and appropriate drill bit, create holes in the concrete for the wedge anchors. – Remove the dust or debris in the holes so they can’t affect the quality of installing the wedge anchors. – Insert the wedge anchor in the holes or through a base and concrete. – Tighten the wedge anchor using a spanner.
How to install a wedge anchor?
Install washer and nut onto the threaded end of the Red Head® wedge anchor, leaving the nut flush with the top of the anchor body. This will protect the threads during installation. Insert Red Head® through the fixture be fastened and into the hole in the concrete, using a hammer strike the nutted end of the Red Head® wedge anchor until the
What is a wedge anchor used for?
Concrete Wedge Anchors are heavy-duty anchors used to secure materials and equipment to solid concrete masonry surfaces. They 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 anchor’s bottom.
