Wedge Bolts: Concrete Anchoring, Installation, and Load Strength

This page delves into wedge bolts, concrete/masonry anchors with a cylindrical shank, tapered end, and wedge mechanism that expands when tightened, gripping hole walls. It explains their quick installation: drill hole, insert bolt, tighten nut to expand wedge—no curing time (unlike epoxy). Materials (high-strength steel, often galvanized) and advantages (high tensile/shear load, vibration resistance, works in cracked concrete) are discussed, along with applications in construction (anchoring brackets, handrails), commercial buildings (signage, panels), and infrastructure. The content covers factors affecting strength (concrete quality, hole size, torque) and compares them to other anchors, making it essential for concrete fastening.

Frequently Asked Questions

What is a wedge bolt?

A wedge bolt is a type of anchor bolt designed to secure objects to concrete, masonry, or stone. It features a cylindrical shank with a tapered end and a wedge mechanism (a separate wedge or an integrated one) that expands when the bolt is tightened. As the nut is turned, the wedge is drawn up the tapered end, expanding the shank against the walls of the pre-drilled hole, creating a secure, permanent anchor.

Grace Wilson

As a DIYer, these carbon steel wedge bolts are perfect for mounting shelves and brackets to my concrete garage walls. The 3/8" diameter is sufficient for moderate loads, like tool cabinets and pegboards, and the zinc plating protects them from garage moisture. I love how quickly they install—no messy adhesives or waiting times. While they're not suitable for extremely heavy loads, they're a great value for home-based concrete anchoring tasks.
