Anchor bolts in concrete - sizes and types , tips for choosing

This type of fasteners used for installation of various designs for all types of concrete products, not only full-bodied, but also cellular.Structurally anchoring bolts consist of two main parts - a spacer member and studs.The technology is the same, the only difference in linear parameters, shape and other "devices".

All products have their numerical designations (in "mm").For example, 8/10 x 50. decrypted numbers?

• first - Thread Size (8).
• second - diameter (10).
• third - Length (50).

What size are the anchor for concrete?

• thread - from M5 to M20.
• diameter - from 6 to 24.
• length - from 18 to 400.

Choosing the appropriate size of products - this is not all.We need to think about the convenience of the production assembly work, especially those operating items (devices) that are attached.Therefore, to have a more complete picture of the anchor bolts, should indicate on the main varieties of this type of fixture (on dowels here).

With washer

These products are used, if you need something tightly pressed against the surface of the fixing.For example, the body of the household appliance, piece of furniture, "hinged" type.

With nut on the end of

With its conveniently placed at a height of massive objects.Corresponding holes in the housing "worn" on the wall in the predetermined bolts, and then fixing is performed at the place of the nut.

C ring, hook

As a rule, they are used to set the lighting, the installation runs utilities and in some other cases.

Selection of the appropriate size bolts made individually for each dockable product.The rule is simple - the more massive the object, the thicker should be the fixture.As for length, it should be guided as to the thickness of the foundations on which the installation is made.

In principle, this information is sufficient to make the best choice.But in particularly problematic cases should be familiar with data on the maximum load in the attached table, which, in addition, the correction factors are listed on the size and the recommended distance.
