When planning fasteners, your mind likely conjures images of conventional options such as screws and bolts. Over centuries, screws and bolts have served the purpose of connecting objects and surfaces. Nonetheless, a realm of alternative fasteners exists, including the versatile clevis fastener.
Demystifying the Clevis Fastener
As shown in the accompanying image, the clevis fastener, alternatively referred to as a “clevis,” showcases a distinctive U-shaped hook design. Within its open structure, there exist two holes, each located on a prong, facilitating the insertion of a pin. When the clevis is appropriately positioned, a pin is introduced through these apertures. To ensure secure placement, a split pin can be added through the pin. These clevis fasteners find frequent application in automobiles, aircraft, boats, and construction machinery, serving to connect control elements effectively.
The Parts of a Clevis Fastener
Various types of clevis fasteners (outlined below) exist, but the prevalent variant comprises three primary components:
- Clevis: The central U-shaped component of the clevis fastener goes by the name of “clevis.”
- Tang: Serving as a pin-like element, the tang is positioned amidst the clevis prongs, with the flexibility of insertion and removal.
3. Clevis Pin: For stabilizing the tang onto the clevis, a clevis pin is employed, firmly holding the tang in position.
Threaded vs. Non-Threaded Clevis Pins: A Comparison
Clevis pins come in two variations: threaded and unthreaded. Threaded pins feature threading only at the head, while unthreaded pins have a rounded head without threads. Threaded pins typically provide greater stability and security compared to unthreaded ones, as they can be partially screwed into the clevis.
The Different Types of Clevis Fasteners
The prevalent type of clevis fastener is known as a shackle. It adheres to the previously mentioned design, comprising a clevis, tang, and clevis pin.
An alternative clevis fastener variant is the bracket. Bracket clevis fasteners exhibit a rectangular-shaped hook that incorporates apertures for additional fasteners like screws or bolts.
Another variation is the clevis hanger, which includes not just one but two clevises. Within a clevis hanger, you’ll find the customary U-shaped shackle clevis alongside a V-shaped clevis, interconnected through a clevis pin or another fastening mechanism.
Lastly, clevis rod ends possess a U-shaped configuration with a base-centered aperture. Typically fabricated through machining, they include a threaded hole to enhance stability and security.
