Simpson Strong Tie STB2-50512P1 Wedge Anchor 20 Pack

Product Description

The SIMPSON STRONG TIE STB2-50512P1 is a wedge anchor designed for securing structural elements to concrete substrates. Measuring 1/2 inch in diameter and 5-1/2 inches in length, this anchor uses a mechanical wedge expansion mechanism that engages the concrete as the nut is tightened, creating a reliable load-bearing connection. It ships in a 20-piece package unit, making it practical for job-lot purchasing on larger installations. Structural contractors, concrete framers, and general construction trades rely on this type of anchor for applications demanding predictable tensile and shear performance in solid concrete.

This wedge anchor is suited for both residential and commercial construction where through-bolting into concrete is required. Typical applications include anchoring sill plates, steel column baseplates, equipment pads, structural ledgers, and heavy machinery to poured concrete floors, walls, and foundations. The 1/2-inch diameter and 5-1/2-inch length provide the embedment depth needed for medium-to-heavy load conditions in standard concrete construction.

Key Features

• Wedge expansion design develops holding strength as the fastener nut is torqued
• 1/2 inch diameter x 5-1/2 inch length suits medium-to-heavy structural anchoring tasks
• Corrosion-resistant finish for durability in exposed or demanding site conditions
• Sold in a 20-piece package for efficient job-site procurement
• Suitable for residential and commercial concrete anchoring applications

Compatibility

Designed as an OEM-style wedge anchor for use in solid poured concrete applications meeting minimum compressive strength requirements typical for structural anchoring.

Installation Notes

Installation should be performed by qualified contractors following applicable building codes, including IBC and ACI standards for anchor design and placement. Drill a hole in concrete matching the anchor diameter using a hammer drill and carbide-tipped bit, then clean the hole of debris before inserting the anchor. Torque the nut to the manufacturer-specified installation torque value listed in the Simpson Strong-Tie specification sheet for this anchor size and embedment depth. Never install into cracked, deteriorated, or insufficiently cured concrete.
