How many types of anchor fastener are there?
There are two types of anchor fasteners namely, mechanical anchor fasteners and chemical anchor fasteners, each of them is discussed below.
What is wedge anchor?
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 are anchors fasteners?
An anchor bolt is a used type of fastener that’s designed to connect one or more objects to a concrete surface. With concrete being brittle, you can use conventional bolts for applications such as this. To ensure the connected object or objects remains in place, you must use anchor bolts.
Which is better wedge anchor or sleeve anchor?
The wedge anchor, drop-in anchor and concrete strike anchor can only be used in solid concrete and have the highest & most consistent holding values in concrete. Concrete sleeve anchors can be used in concrete, brick or block but their holding values are less in terms of shear and pullout values.
Which anchor fastener is best?
Cast-in-place bolt anchors are the strongest and by far most convenient form. The bolt is embedded into the main body of the structure with a hexagonal nut and washer at the head. These are used typically in steel-concrete composites and shear connectors.
How deep is a wedge anchor?
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.
Can wedge anchors be removed?
Wedge anchors can be removed from concrete in one of three ways: Use a saw or grinding wheel to cut the anchor off just above the surface, and pound the rest flat with a hammer. Or you can simply place the Boltbreaker over the protruding rod, rock back and forth, and rotate until the rod breaks off.
Do you hammer in concrete anchors?
Concrete screws provide a quick, easy and incredibly strong way to fasten to concrete. And best of all, there’s no hammering required or anchor or shield to install. All you do is drill a hole and drive in the screw. That’s it.

How are pin type anchor bolts from Ita fasteners?
Pin type anchor bolts from ITA fasteners have interior holes which can extend upto the length of the anchor. The upper portion is where the drive pin is inserted. It is also where the threaded anchor is inserted. To sustain loads, these pin type fasteners use a friction locking principle.
How are pin type anchor bolts used in masonry?
To sustain loads, these pin type fasteners use a friction locking principle. The outer surface could be designed with corrugations to resist turning and provide proper balance. They mostly come in the form of a zinc plated dichromate material. Pin type anchor bolts find their use in soft masonry to reduce the effect of vibration and pressure.
What kind of anchors do you use at Grainger?
Drive Pin Anchors. Use a hammer anchor from Grainger for light-duty or heavy-duty applications. Set hammer anchors with a hammer, inserting or expanding them into predrilled holes in concrete, brick or cement block. You’ll also find crimp anchor and anchor rivet styles here.
