Stewart Fastener 7400 Wedge Anchor 0.25x1.75 in

Product Description

The STEWART FASTENER 7400 is a wedge anchor designed for anchoring into concrete and masonry substrates. Measuring 0.25 inches in diameter by 1.75 inches in length, this fastener uses an expansion-clip mechanism that wedges against the base material as the nut is tightened, creating a secure mechanical hold. Wedge anchors of this size are standard hardware for light-duty structural attachments, equipment mounting, and fixture installation in concrete floors, walls, and ceilings. Licensed contractors and experienced tradespeople select this anchor when a reliable, permanent fastening point is required in solid concrete or grout-filled block.

This anchor is suited for residential and light commercial applications where a 0.25-inch diameter fastener meets the load requirements of the installation. Common use cases include attaching electrical conduit straps, mechanical equipment bases, framing connectors, and similar hardware directly to concrete or masonry surfaces. It is installed using a standard rotary hammer drill and appropriate bit, making it a practical choice for HVAC techs, electricians, and plumbers securing equipment to concrete slabs or walls.

Key Features

• 0.25-inch diameter by 1.75-inch length for light-duty concrete anchoring applications
• Expansion wedge design creates a permanent mechanical hold as the nut is torqued
• Compatible with standard rotary hammer drilling and installation workflow
• Compact size suits tight clearance conditions common in mechanical and electrical trade work

Compatibility

Designed as a standard 0.25-inch wedge anchor for use in solid concrete and grout-filled concrete masonry unit installations where the base material depth accommodates the anchor embedment length.

Installation Notes

Installation requires a licensed or qualified tradesperson following applicable building codes and anchor manufacturer load tables. Drill the hole to the correct diameter and minimum depth using a carbide-tipped rotary hammer bit before inserting the anchor. Ensure the concrete substrate is fully cured and free of voids or delamination at the anchor location. Never install wedge anchors in cracked concrete without engineering review, and do not exceed the rated load for the anchor diameter and embedment.
