What are Hilti anchors for?
Injectable Adhesive Anchors Hilti is a global leader in chemical anchor systems, offering a broad range of injectable mortars for anchoring and rebar applications in materials such as concrete and masonry.
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.
How do Hilti expansion anchors work?
Torque-controlled expansion anchors like the KWIK Bolt TZ and HSL-3 anchors use follow-up expansion to increase the expansion force in response to increases in loading beyond the installation torque-induced preload or to adjust for changes in the state of the base material (cracking).
How do you remove Hilti concrete anchors?
Wedge anchors: When drilling a hole for a wedge anchor, drill twice the length of the wedge anchor. This will allow for the wedge anchor to be pounded into the hole until flush with the base material. To be removed, wedge anchors can be sawed off with a hacksaw or cutoff wheel at the surface of the base material.
How much weight can concrete anchors hold?
Masonry and concrete anchor types are considered light-duty, medium-duty or heavy-duty, based on how much weight they can support. Light-duty anchors are good for wall hangings that weigh up to 50 pounds. Medium-duty anchors are good for wall hangings that weigh up to 200 pounds.
How deep does a concrete anchor need to be?
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 strong are ground anchors?
They can achieve a holding capacity of up to 3,000 kN. They have low environmental impact.
What is the difference between wedge and expansion anchors?
Wedge anchors are designed not to be used in other masonry materials such as brick or hollow block. The expansion clip on the wedge anchor is placed on the anchor body in a manner and location that makes the expansion tolerance location critical.
