Frequently Asked Questions
- What base material is the DIA25SS Drop-In Anchor designed for?
- The DIA25SS is designed for use in solid base materials, specifically concrete applications where a flush-mount expansion anchor is required.
- What size threaded rod does the DIA25SS accept?
- This drop-in anchor is designed to accept a 1/4-in. threaded rod. Minimum thread engagement should be equal to the nominal diameter of the threaded insert.
- What drill bit size is required to install the DIA25SS?
- A 3/8-in. drill bit is required to create the correct-diameter hole for this anchor. A fixed-depth stop bit is also available to ensure you drill to the correct depth every time. Note that oversized holes will make it difficult to set the anchor and will reduce the anchor's load capacity.
- Why is Type 303/304 stainless steel used for the DIA25SS?
- The anchor body and expander plug are both made from AISI 303 stainless steel, with the anchor body meeting the chemical requirements of ASTM A582. The Type 303/304 stainless-steel construction provides enhanced corrosion resistance compared to standard carbon steel anchors, making it well-suited for environments where moisture or corrosion exposure is a concern.
