Molly bolts, also known as hollow wall anchors, are a type of fastener designed for use in drywall or other hollow materials. They consist of a metal sleeve that expands behind the wall as a screw is tightened into it. The expanding sleeve provides a solid grip, creating a secure attachment point for hanging objects.
Different Types of Screw Heads
Screw heads come in various shapes and designs, each serving different purposes. The most common types of screw heads include:
1. Philips Head
Philips head screws have a cross-shaped indentation on the top, requiring a matching screwdriver or drill bit for installation. While these screws are widely used and compatible with many applications, they are not suitable for use with molly bolts.
2. Flat Head
Flat head screws have a flat top with a single slot for a flathead screwdriver. These screws are not recommended for molly bolts, as they do not provide the necessary grip and expansion behind the wall to secure the anchor.
3. Hex Head
Hex head screws have a hexagonal shape on the top, requiring a hex key or wrench for installation. While these screws offer a more secure grip compared to flathead or Philips head screws, they are not recommended for use with molly bolts.
4. Round Head
Round head screws have a rounded top with a slotted head, allowing for easy installation using a flathead screwdriver. While these screws are suitable for many applications, they are not the best choice for molly bolts.
Screw Types Compatible with Molly Bolts
To ensure optimal performance and a secure anchor, certain screw types are recommended for use with molly bolts. The most suitable screw type for molly bolts is the pan head screw. Pan head screws have a low, rounded top with a slotted head or Phillips head, making them compatible with molly bolts’ expanding sleeves.
Benefits of Using the Recommended Screw Type
Using the recommended screw type, such as pan head screws, with molly bolts offers several benefits:
- Enhanced Grip: The design of pan head screws allows for maximum expansion behind the wall, increasing the anchor’s grip strength and overall stability.
- Easy Installation: The slotted or Phillips head of pan head screws makes installation quick and hassle-free, ensuring a secure attachment of the molly bolt.
- Seamless Appearance: The low-profile design of pan head screws offers a clean and seamless look when used with molly bolts, making them an ideal choice for visible applications.Not all screw types are suitable for use with molly bolts. While various types of screw heads exist, including Philips, flat, hex, and round heads, none of them are recommended for securing molly bolts. The most compatible screw type for molly bolts is the pan head screw, which offers enhanced grip, easy installation, and a seamless appearance. By using the appropriate screw type, you can ensure a strong and secure anchor for hanging objects in drywall and other hollow materials.
