Shelving Concepts uses a wedge anchor to secure racking to the concrete but over the last few years, a few customers have asked for lag screws instead of wedge anchors. Let us look at the pros and cons of using a lag screw as an alternative to a wedge anchor.
What is a Lag Screw?
A Lag Screw is a high-strength screw anchor used in cracked and uncracked concrete as well as uncracked masonry. Lag Screw anchors are designed to be used when metal or wood is securely fastened to concrete material. This application is used more commonly in higher load capacity and is vibration resistance than a standard wedge anchor.
The Pros of Lag Screws
Most applications do not require a lag screw, but some projects will require them when you are collaborating with engineers. Locations that are prone to earthquakes too may require a lag screw over a wedge anchor to. Let us look at the pros and cons of using a lag screw anchor.
- High Strength and durability
- Low installation torque
- Designed for a variety of applications
- The screw anchor is easy to remove
- Used for permanent or temporary applications
- Does not require a specific drill bit
- Hex head washer requires no other washer in application
- Hex head washer provides a clean look for the installation
The Cons of Lag Screws
- Extra time for predrilling the holes for each lag screw
- The complexity of the lag screw requires experience to use
- Risk of splitting wood in the case of wood applications if not installed correctly
- Requires a wrench or socket to tighten them, loss of work time
- Considered overkill in areas where they are not required
