Are Tapcon concrete anchors Good?

Tapcon+ unmatched performance in concrete, block and brick applications make them an excellent alternative to expansion anchors, plugs, lag shields and have a blue corrosion resistant coating that enables them to withstand the harshest conditions.

Can you use wedge anchors in concrete?

A wedge anchor is a mechanical type expansion anchor that consists of four parts: the threaded anchor body, the expansion clip, a nut, and a washer. It is designed for use in solid concrete only. These anchors provide the highest and most consistent holding values of any mechanical type expansion anchor.

What is the best way to anchor into concrete?

Drill a pilot hole at the proper location with a hammer drill and masonry bit to the depth your screw will penetrate. Tap the plastic anchor into the hole. It should fit snugly but drive in easily with a hammer. If the hole gets a bit large, use a bigger screw to push the plastic against the walls of the hole.

How much weight can a Tapcon hold?

1,360 lbs. *A safety factor of 4:1 or 25% of ultimate pullout/shear value is generally accepted as a safe working load.

How deep should anchor bolts 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.

Technical Specifications for Wedge Anchors

How many wedge anchors do I need?

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”.

How do you install a wedge anchor in concrete?

How tight should wedge anchors be?

How much should I tighten the nut on the anchor? Once the nut is finger tight, use a wrench to tighten two to three full turns. This should ensure proper installation torque.

What grade are wedge anchors?

Stainless Steel 316 – the highest grade of stainless steel that concrete wedge anchors are made from, and are for use in submerged applications and where some chemicals are present, such as chlorine in and around swimming pools.

Can you use wedge anchors in brick?
