Lag Shields: Working On Concrete And Block Projects

Also known as lag screw shields, lag screw anchors or simple lag shields, these are implements used for fastening things together like block, concrete, and brick. Lag shields are usually built as two part expansion. This is preassembled into a single unit that is self contained. It takes the appearance of a shell but you'll find tapered threads running the length of the inside of the anchor. On the outside of this tool, you can circumferential ribs going from the bottom through most of its length. For the back end, you'll find spaced ribs along the length of it too.

When you fasten lag shields up, you can unbolt any object and remove it easily. In line with what the implements are made of, they're usually made of a zinc alloy referred to as Zamak 5. The bottom line is this material provides the lag shields with rust proof qualities. Besides the material, you'll have two main choices when buying them. There are short anchors and long anchors. You only use the short ones for anchoring high grade concrete and the long ones are used for low grade material.

The main features that lag shields have are as follows. They're used together with lag screws. They can be used in cinder block, stone, tile and concrete for capabilities with light to medium duty and they're also rust proof. What makes these things special is that they have a four way expansion and this makes the strong and secure grip to base material possible. Short lag shields can be used in masonry to minimize drilling time and the long lag anchors can be used for higher holding values with soft base materials. Approvals for these anchors have to meet ASTM specification and GSA specification.

As it was mentioned above, there are two kinds of lag shields, the long and the short. How would you know if the best one to use in a project is the long one? You have to determine how thick the materials you'll be working on are. You take this figure and add it to the lag shields length and add another half inch to the total sum. What you're looking for with these anchors is the screw tip protruding from the anchor. That indicates proper expansion with your project and you have a sturdy and secure structure.

When you buy the right size lag shields, installing them wouldn't be that much of a problem. There are three main steps that go into the installation. You first have to drill the hole onto the surface of the application. When you're done with that, you can insert the lag shields into your predrilled holes. Follow it up with the screw and then tighten it up. Knowing this method, you can do nicely with installing the screws and the shields. For the best effects, you have to know about the more detailed instructions for installing the implements as well as the requirements for lag anchor spacing.
