Frequently Asked Questions (FAQs)
1. What is an expansion bolt used for?
Expansion bolts are used to securely fasten heavy objects to walls or floors. They can handle both vertical and horizontal loads. By tightening the bolt, the nut on the opposite end pulls into the shell, expanding it outward and wedging it inside the pre-drilled hole in the wall or floor.
2. Which is better, anchor bolt or expansion bolt?
Both anchor bolts and expansion bolts have their uses. Anchor bolts provide strong support by anchoring pieces of wood or steel together. On the other hand, expansion bolts offer even more strength by expanding inside pre-drilled holes in masonry walls or concrete foundations.
3. Are expansion bolts strong?
Yes, expansion bolts are known for their strength. They are suitable for structural connections as they can resist loading in both tension and shear. For example, a ¾-inch diameter expansion bolt can handle approximately 12,500 pounds of tension and 11,500 pounds of shear.
4. How much weight can an expansion bolt hold?
An expansion bolt known as a molly wall anchor can support up to 50 pounds. This type of expansion bolt is a screw encased in a metal sleeve that expands. It can be used to hang pictures, mirrors, and small shelves. The screw can also be removed and reinserted for future use.
5. Can expansion bolts be used in drywall?
Yes, expansion bolts can be used in drywall. Plastic drywall anchors, which are a type of expansion anchor, are versatile and can be used to hang pictures, mirrors, and small shelves. They can also be inserted into other materials like cinder block, brick, and concrete.
6. What is the strongest concrete anchor bolt?
Epoxy anchors are considered the strongest type of concrete anchor bolt. However, they require more time and effort to install. Epoxy anchors consist of a threaded rod with a two-part epoxy resin that is mixed and applied to the rod before it is inserted into the pre-drilled hole.
7. Do expansion bolts work in concrete?
Yes, some expansion anchors are specifically designed for use in solid base materials like concrete. However, there are also expansion anchors available that can be used in a variety of masonry materials, such as brick or block. Additionally, certain anchors can be used in natural base materials like stone.
8. Do expansion bolts go into studs?
No, expansion bolts should not be placed in stud locations. Wall anchors need the hollow space behind the drywall to expand properly. If they are placed where the stud is located, they won't be able to make it all the way into the wall and won't provide the necessary security.
