Butler Fasteners

Butler Building fastener - Scrubolt vs. self-drilling screw

Various types of fasteners are used in Butler buildings to assemble and secure components. Here are some common types of fasteners you might find in Butler buildings:

  1. Screws and Bolts:

    • Self-Drilling Screws: These screws have a drill bit-like point, allowing them to drill and tap their own hole in metal components. They are commonly used for attaching metal panels to structural members.

    • Hex Head Bolts: Hex bolts are used in structural connections. They have a hexagonal head for easy tightening with a wrench.

    • Anchor Bolts: Anchor bolts are embedded into concrete foundations and used to secure the building columns to the foundation.

  2. Nuts and Washers:

    • Hex Nuts: These nuts have a hexagonal shape and are used in conjunction with hex bolts to secure components together.

    • Lock Nuts: Lock nuts have a nylon insert or other locking mechanism to prevent them from loosening due to vibration.

    • Washers: Washers are used under nuts or bolt heads to distribute the load and provide a smooth surface for tightening.

  3. Rivets:

    • Blind Rivets: Also known as pop rivets, blind rivets are used when access to the backside of a joint is limited. They are inserted through a hole and "popped" on the blind side to secure components.

  4. Clips and Brackets:

    • Purlin and Girt Clips: These clips are used to attach secondary structural members (purlins and girts) to the primary structural members (columns and rafters) in a Butler building.

    • Brackets: Various brackets are used for connecting different building components, such as roof trusses, girts, and purlins.

  5. Anchors:

    • Concrete Anchors: Used to anchor building components to concrete surfaces, such as attaching base plates to the foundation or securing equipment.  These are not provided with the Butler building package.

  6. Fastener Accessories:

    • Screw Caps and Sealing Washers: Used to cover screw heads and provide weather resistance, preventing leaks.

    • Butyl Tapes and Sealants: These are used to create weather-tight seals between panels and components.  Butler's product is called, "Panlastic" and is specially formulated to have better elasticity and incorporate small beads to ensure a minimum seal thickness.
