Frequently Asked Questions

What rod size is compatible with the DIA62SS drop-in anchor?

The DIA62SS is designed for use with 5/8-in. threaded rod. Minimum thread engagement should be equal to the nominal diameter of the threaded insert.

What drill bit diameter is required to install this anchor?

A 7/8-in. drill bit is required. Using a fixed-depth stop bit is recommended to help ensure you drill to the correct depth every time. Caution: Oversized holes will make it difficult to set the anchor and will reduce the anchor's load capacity.

What base materials is the DIA62SS anchor suitable for?

This drop-in anchor is designed for use in solid base materials, specifically concrete applications where a flush-mount installation is required.

What material is the DIA62SS anchor made from, and why does it matter?

The anchor body and expander plug are both constructed from AISI 303 stainless steel, which meets the chemical requirements of ASTM A582. The Type 303/304 stainless-steel construction provides enhanced corrosion resistance compared to carbon steel alternatives, making it well suited for environments where moisture or corrosive conditions are a concern.
