Molly bolts are a type of fastener that has become quite popular in the hardware industry due to its unique properties. They are a fantastic alternative to traditional screws and nails when attaching objects to drywalls. However, if you are new to DIY projects, you might wonder what a Molly bolt is, how it works, and its benefits. This blog post has compiled a detailed guide to help you understand everything you need about Molly Bolts. So, let’s dive in!

What is Molly Bolt?

Molly Bolt is a type of anchor bolt made from low carbon steel that is used for heavy-duty fastening and fixture mounting. It is designed to provide secure, damage-free installation into masonry, concrete, or wood surfaces with minimal effort. The ribbed design helps to increase holding power while the unique configuration enables it to be easily tightened without having to use any tools.

Molly Bolts Properties:

Molly bolts come in different sizes and materials. The most commonly used materials are steel and nylon. Steel Molly bolts are stronger and can hold heavier items, whereas nylon bolts suit lightweight objects. Generally, it is essential to choose the right size of Molly bolt that can accommodate the wall’s thickness and the object’s weight. Additionally, Molly bolts are easy to install and do not require pre-drilling before insertion.

Molly Bolts Uses and Applications:

Molly bolts are suitable for various applications, including hanging shelves, mirrors, picture frames, and other decorative items. They can install towel racks, curtain rods, and other bathroom accessories. One of the significant advantages of using Molly bolts is that they work well for objects that cannot be hung using nails or screws. A Molly bolt can be used as long as the wall is hollow.

How to Use Molly Bolts:

Using a Molly bolt is a straightforward process. The first step is to drill a hole into the wall corresponding to the sleeve size. The bolt is then inserted, and the sleeve is pushed into the hole until it is flush with the wall. The screw is then threaded into the sleeve, and as it is tightened, the sleeve expands, creating an anchor that holds the object firmly in place.

Tips for Using Molly Bolts:

While Molly bolts are easy to install, a few tips can help you get the best results. Firstly, ensure the hole is drilled at the correct depth so the sleeve can fully expand. Secondly, ensure that the screw is not overtightened, which can cause the sleeve to crack. Lastly, when using Molly bolts to hang objects on ceilings, always use more than one bolt for added security.


In conclusion, Molly bolts are a fantastic alternative to traditional screws and nails, especially when holding objects on drywalls. They are easy to install, have unique properties, and come in different sizes and materials. Whether you want to hang a picture frame, mirror, or towel rack, Molly bolts can provide a reliable anchor to keep your items secure. Following the tips mentioned in this blog post will surely get the best results when using Molly bolts for your next DIY project.
