Derailleur hanger fasteners: Screws, Nuts, Bolts

Replacement derailleur hanger fastener for various bike models.

Derailleur hanger fasteners are the components that attach the derailleur hanger to the frame of a bicycle. The derailleur hanger is a small, often replaceable part of the bike frame that connects the rear derailleur to the frame and enables the derailleur to shift gears smoothly.

Screws, nuts, and bolts are the most commonly used types of fasteners for derailleur hangers. These fasteners can be made from a variety of materials, including steel, aluminum, or titanium. The specific type and size of fastener will depend on the bike frame and derailleur hanger.

Screws are small, threaded fasteners that are often used to secure the derailleur hanger to the bike frame. They may be Phillips head, flat head, or hex head screws. In some cases, the screws may be self-tapping, which means they can be driven directly into the bike frame without the need for a separate nut or threaded insert.

Nuts are typically used in combination with bolts to attach the derailleur hanger to the frame. The nut is threaded onto the end of the bolt and tightened to hold the derailleur hanger in place. Nuts may be standard hex nuts or specialized flanged nuts that are designed to grip the frame more securely.

Bolts are longer than screws and are typically used in combination with nuts to attach the derailleur hanger to the frame. Bolts may be hex head or socket head bolts, and they may be partially threaded or fully threaded depending on the specific application.

It's important to use the correct type and size of fastener when attaching the derailleur hanger to the bike frame. Using the wrong fastener can result in a loose or damaged derailleur hanger, which can affect shifting performance and potentially cause damage to the frame.
