Toggle Bolts, also known as Molly Bolts or Butterfly Anchors, are light-duty, hollow wall anchors specifically designed for use in hollow block, drywall, and other hollow base materials. The toggle bolt is a two-part fastener system consisting of a spring wing toggle and a machine screw. With wings that open inside the wall, spreading the weight of the secured item over a large area, toggle bolts brace against the wall and anchor the fastener securely. Used as an alternative to other hollow wall anchors, steel toggle anchors are more temperature resistant. As a full service toggle bolt supplier, you’ll find a large selection of butterfly anchors with bolt sizes ranging from 1/8” up to 1/2” and lengths up to 6” and supplied with a zinc finish.

Installing Butterfly Anchors (Toggle Bolts)
- Drill the required hole through the base material. In denser materials such as high strength concrete, it’s recommended to drill the hole 1/16" larger.
- Insert the toggle bolt through the fixture to be fastened, thread on wings, then fold the wings completely back and insert through the hole until wings spring open.
- Then, pull back on assembly to hold the wings inside the wall to prevent the wings from spinning while tightening bolt. Turn the bolt with the screwdriver until firmly tightened.
