Choosing The Best Screw Lock For Anchors: A Secure Guide

Screw locks for anchors are an essential component of any anchoring system, providing security and stability. The best screw lock for anchors will depend on the specific application and requirements.

For example, E-Z Ancor offers a range of screw locks for anchors, such as the Toggle Lock and Twist-N-Lock series, which are designed for drywall applications and can support weights of up to 100 pounds. These screw locks are easy to install, with some not requiring pre-drilling, and are ideal for hanging various items.

Other factors to consider when choosing the best screw lock for anchors include the type of anchor, the weight capacity, ease of installation and removal, and the surface or material they will be used on.

Expansion Drywall Anchors

Expansion anchors are true to their name, as they spread to create a tight bond with the wall and are designed to hold lightweight items. The anchor's shank (tapered end) is split in half. To install, first drill a pilot hole in the wall, then fit the anchor into the hole and use a hammer to lightly tap the anchor head flush with the wall. Finally, insert a screw into the anchor, and the split ends of the shank will spread and expand to put pressure on the inside of the drywall, holding the anchor securely in place.

When using expansion drywall anchors, it is important to ensure that the drywall is in good condition. They can slip out of patched or water-damaged drywall. It is also crucial to not exceed the anchor's weight limit and to stay at half of the weight limit, especially when hanging valuable items. For heavier items, it is recommended to use multiple anchors to distribute the weight evenly.

There are various options available for expansion drywall anchors, such as plastic ribbed anchors, winged plastic expansion anchors, and self-drilling drywall anchors. Plastic ribbed anchors have a sharp thread and a pointed tip on one end, with a flange on the other to prevent them from being pulled through the wall. Winged plastic expansion anchors have wings that prevent the anchor from pulling out, while self-drilling drywall anchors have sharp teeth on one end, eliminating the need for pre-drilling.

Threaded Drywall Anchors

When compared to expansion anchors, threaded drywall anchors provide greater support. While expansion anchors can typically only bear weights of up to 25 pounds, threaded drywall anchors can be rated for loads of up to 75 pounds. This makes them suitable for hanging pictures, mirrors, and shelves.

To install a threaded drywall anchor, use moderate pressure to twist the anchor into the drywall. A screwdriver or a cordless drill with a screwdriver bit can be used for this purpose. Care should be taken not to overtighten the anchor, as this can cause the thread to damage the drywall and loosen the hold. To remove the anchor, simply turn it anti-clockwise to back it out of the wall.

One recommended product in this category is the E-Z Ancor Twist-n-Lock Drywall Anchor, which is available at Home Depot for $29.98. These threaded anchors are strong and budget-friendly, and they make an audible click to indicate when they are correctly installed.

Molly Bolts

To use a molly bolt, you first need to drill a hole into the wall. The bolt has a lip that is wider than the hole, which prevents it from falling behind the wall. It also has features such as cleats or spikes that stop it from rotating when being compressed. Once the bolt is in position, a machine screw is inserted and tightened, causing the anchor to expand and grip the inside of the hole. This expansion is what gives molly bolts their holding power, which can range from 25 to 55 pounds, depending on the size of the bolt.

While molly bolts are a good option for hanging objects on hollow walls, they are not as readily available as some other types of anchors, such as threaded drywall anchors or toggle bolts. They also require a fair amount of torque to work properly, and if they are overtightened, they can be difficult to remove cleanly. Some users have also reported issues with molly bolts not expanding correctly, which can lead to failures and damage to walls.

Overall, molly bolts can be a good option for hanging objects on hollow walls, but they may require some trial and error to use successfully. It is important to follow the manufacturer's instructions carefully and not to overload the bolts beyond their weight capacity.

Winged Plastic Anchors

These anchors are ideal for hanging heavy items such as shelves, cabinets, mirrors, and artwork. They offer a strong holding power, with a maximum capacity of up to 100 pounds for metal toggles and 20 pounds for plastic winged anchors. It is important to note that the weight capacity may vary depending on the size and material of the winged plastic anchors.

When using winged plastic anchors, it is crucial to follow the correct installation process. First, drill a hole in the wall that is slightly larger than the diameter of the anchor. Insert the anchor into the hole and use a wand to expand the wings. Finally, screw in the anchor until it is flush with the wall.

One advantage of winged plastic anchors is their ease of installation. They do not require specialized tools, and the wings ensure a secure hold without the need for additional hardware. Additionally, they are often made of durable materials, such as nylon or zinc-coated metal, making them suitable for various wall types, including drywall, plaster, and concrete blocks.

However, it is important to consider some potential challenges when using winged plastic anchors. One issue is that they can be difficult to keep level during installation, affecting the overall stability of the anchor. Additionally, the weight capacity of these anchors may not be sufficient for very heavy items, and using multiple anchors may be necessary for heavier loads.

Toggle Bolts

E-Z Ancor Toggle Lock

E-Z Ancor Toggle Lock is a popular choice for drywall anchors, offering a simple installation process and impressive weight capacity. The E-Z Ancor Toggle Lock can hold up to 100 pounds, which is significant for a self-drilling anchor. Its smart design makes it easy to install, even without a pre-drilled hole. The toggle pivots and secures in place with the included Phillips-head screw, ensuring a strong hold.

The E-Z Ancor Toggle Lock is made of rust-resistant zinc, making it ideal for moisture-resistant drywall in bathrooms and other damp areas. The pack typically includes 10 anchors and screws, providing a convenient all-in-one solution. However, it's important to note that the arrows on the anchor can be challenging to see, and proper alignment is crucial for correct installation.

Installation Process

The installation process for toggle bolts, including the E-Z Ancor Toggle Lock, is relatively straightforward. Here's a step-by-step guide:

• Drill a hole in the wall: The first step is to drill a hole in the wall where you plan to insert the toggle bolt. The size of the hole will depend on the specific toggle bolt you are using, so be sure to check the manufacturer's instructions.
• Insert the toggle bolt: Hold the metal channel flat alongside the plastic straps and slide it through the hole you drilled. Pull the plastic ring straight while sliding the plastic cap along the straps until the cap is flush with the wall.
• Snap the straps: Place your thumb between the plastic straps and push them side to side to snap them off at the wall. This will secure the toggle bolt in place.
• Attach the item: Place the item you want to hang over the toggle bolt and insert a bolt or screw through it. Tighten it until it is flush against the item, then stop.

Best Practices and Recommendations

When using toggle bolts, it is important to follow some best practices to ensure a secure and safe installation:

• Weight capacity: Choose a toggle bolt with a weight capacity that is greater than the weight of the object you are mounting. This ensures that the toggle bolt can bear the load securely.
• Toggle bolt size: Select the appropriate size of the toggle bolt based on the thickness of the drywall. A 1/8-inch toggle bolt is typically sufficient for 1/2-inch drywall, while a 3/16-inch toggle bolt is recommended for 5/8-inch drywall.
• Type of toggle bolt: Machine screw thread toggle bolts are recommended over self-drilling toggle bolts as they provide a better grip and holding power.
• Manufacturer's instructions: Always follow the manufacturer's instructions for the item you are mounting, as they may have specific requirements for toggle bolt type and size.
• Consult professionals: If you are unfamiliar with the installation process or have any doubts, it is advisable to consult with professionals before proceeding.
