Toggle Bolts - Butterfly Anchors

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. This type of 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, they 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)

  1. 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.
  2. Insert the 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.
  3. 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.
