L H Dottie Co DAS25 Stainless Steel Drop Anchor 1/4-20

Product Description

The L H DOTTIE CO DAS25 is a stainless steel drop-in anchor designed for secure fastening in concrete and masonry applications. Threaded to accept a 1/4-20 bolt, this anchor is set by expanding inside a pre-drilled hole when the setting tool is struck, creating a flush, permanent anchor point. Stainless steel construction provides corrosion resistance in wet or chemically exposed environments. It is sold individually and is suitable for use by electricians, plumbers, HVAC technicians, and general contractors who need reliable anchoring in concrete substrates.

Drop-in anchors are commonly used in commercial and residential construction to fasten threaded rod, pipe hangers, conduit straps, equipment supports, and mechanical hardware to concrete ceilings, walls, and floors. The 1/4-20 thread size makes the DAS25 appropriate for lighter-load applications such as hanging small-diameter conduit, low-voltage cable trays, and similar trade hardware where a flush, internally threaded anchor point is required in concrete.

Key Features

• Stainless steel construction resists corrosion in wet and chemically exposed environments
• 1/4-20 internal thread accepts standard bolts and threaded rod
• Drop-in expansion design sets flush with the concrete surface
• Single-unit packaging allows for precise quantity purchasing
• Suitable for concrete ceilings, walls, and floors

Compatibility

Designed as an OEM-style drop-in anchor for use with 1/4-20 threaded fasteners in concrete and masonry installations.

Installation Notes

Installation requires drilling a properly sized hole in concrete using a carbide-tipped bit, then driving the anchor flush using the appropriate setting tool. Always follow anchor manufacturer hole-diameter and embedment-depth requirements for the application load. Confirm concrete substrate integrity before setting anchors in overhead applications. Installation should comply with applicable building codes and engineered fastening specifications where structural loading is a factor.
