A wedge anchor is a mechanical type expansion anchor that consists of four parts: the threaded anchor body, the expansion clip, a nut, and a washer. It is designed for use in solid concrete only. These anchors provide the highest and most consistent holding values of any mechanical type expansion anchor.
This pre-assembled high strength, fully threaded, and torque-controlled expansion anchor has a unique safety shoulder in the expansion cone that supports a thick 3-dimple clip engineered to provide high load carrying capability and reduce slip in a variety of installation conditions. Nut and washer included.

Values shown are average ultimate values and are offered only as a guide and are not guaranteed. A safety factor of 4:1 or 25% is generally accepted as a safe working load. Reference should be made to applicable codes for the specific working ratio
Materials / Finishes
- Zinc-plated carbon steel with steel clip
- Hot-dip galvanized carbon steel with 304 stainless steel clip
Features and Benefits
- Length and identification code stamped on head to ease identification pre and post-installation
- Dog-point head prevents point damage during installation
- Fully threaded anchor body accommodates various application thickness
- Enlarged 3-dimple clip
- Increases response in lightweight concrete and requires fewer rotations to achieve desired torque
- 360 º segment contact on clip equalizes load distribution and increases load-carrying capacity
- Unique safety shoulder
- Supports the 3-dimple clip under maximum and ultimate loads, preventing slippage
- Similar products have gradual expansion cone that does NOT have a safety shoulder to support the clip when anchor is under strain.
How deep do wedge anchors need to be?
When installing a wedge anchor, it's important to have a minimum of 2-1/2 inches embedded into the concrete. There should also be at least an inch exposed, enough for the attaching material to grab onto.
Are wedge anchors removable?
To be removed, wedge anchors can be sawed off with a hacksaw or cutoff wheel at the surface of the base material. Tapcon® Concrete Screws: Tapcons are removable because they are threaded screws that tap threads into the concrete, brick or block. ... Remove the nut and washer and the round or flat head of the sleeve anchor.
