How do you use a masonry anchor screw?
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.
What is a masonry anchor?

How much weight can a masonry anchor 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.
Are masonry screws any good?
Masonry screws are a excellent way to fasten any material to masonry . These can be used in stone, brick or concrete and are a fast reliable way of fastening with no expansion force like you would get with wall plugs or shield anchors .
What is the strongest concrete anchor?
Types Of Masonry Anchors Double Expansion Shield Anchors are used primarily used in brick and block. Sleeve anchors are fairly simple to use and are primarily used in brick or block. Wedge Anchors are extremely popular and are one of the strongest anchors for hold strength.
How deep should anchor bolts be in concrete?
Do I need to drill a pilot hole for concrete screws?

How do you screw into concrete without a hammer drill?

How do masonry anchors work?
Most masonry anchors work in one of two ways–either by expanding against the sides of the hole and gripping the concrete (Fig. 1) or by friction against the sides of the hole (Fig. 2). The holding power of any anchor depends on the quality of the concrete and on where the anchor is placed.
Which is better wedge anchor or sleeve anchor?
Because of the surface area available in the design , the sleeve anchors hold better and may even work best where the material is not very stable or drilled well . On the other hand the wedge anchor will work very well in precision drills and will provide strong and reliable locks.
How deep do you drill for wedge anchors?
