Frequently Asked Questions

What is the difference between the DIA and DIAS versions of this drop-in anchor?

The DIA version is made from stainless steel, while the DIAS is the short version made from zinc-plated carbon steel. The DIAS features a lipped edge that eliminates the need for a precisely drilled hole depth, and its shorter length allows for shallow embedment to help avoid drilling into rebar or pre-stressed/post-tensioned cables.

What drill bit size is required for proper installation of the DIA37S?

A 1/2-in. drill bit diameter is required for installation. Caution: oversized holes will make it difficult to set the anchor and will reduce the anchor's load capacity.

What rod size is compatible with the DIA37S drop-in anchor?

The DIA37S is designed for use with a 3/8-in. rod. Minimum thread engagement should be equal to the nominal diameter of the threaded insert.

Does the DIA37S come with a setting tool?

Yes. Short drop-in anchors include a setting tool compatible with the anchor to ensure consistent installation.
