Quarter Turn Fastener

Quarter Turn Fastener: Features and Advantages

Quarter-turn fasteners are versatile and operable manually or with a tool, depending on the stud’s head style. Rotating the stud 90° engages the cross pin with the cam, applying a controlled joint (Ferrule) preload and reaching a mechanical stop. This action locks the joint (Ferrule) securely. Reversing the motion unlocks the system for swift and effortless access. These fasteners create connections under elastic preload, with the spring element generating the preload within the stud or the receptacle. 

Their benefits contain tool-free installation, winged heads or arrow-marked knobs for engagement indication, and enhanced vibration resistance. Ideal for panel and cover attachment, quarter-turn panel fasteners are widely applied in industries like aerospace, automotive, electronics, and furniture. 

Types of Quarter Turn Fasteners and Their Applications

Fivetech prioritizes innovative design and delivers excellence through services like SMT installation and customizable design options. Let’s see the advantages of our unique spring-loaded quarter-turn fastener designs.

Auto Lock

Fivetech’s Auto Lock fastener offers a hassle-free locking mechanism that engages automatically with a simple press of a finger. Unlocking is just as effortless—requiring only a quarter-turn rotation. Engineered with a torsion spring structure, this fastener enhances clamping force, ensuring a firm and stable connection between two boards.

Key Features:

  • Intuitive Water Drop Design: Enhances usability with a comfortable grip and effortless operation.
  • Quick & Secure Fastening: Instantly locks with a press and releases smoothly with a 90-degree turn.
  • Reinforced Durability: Designed with high structural strength for long-lasting reliability.
  • Optimized Spring Mechanism: Improves stability by increasing force between secured boards.

Its ergonomic water drop single-wing design even allows one-finger operation, making it a convenient solution.

Key Features:

  • Effortless Unlocking & Auto-Rebound: A light push rotates the mechanism 90 degrees, returning to its locked position automatically.
  • Multi-Function Design: Can be used as a securing mechanism, a stabilizing bar to prevent movement, or a wire organizer for server chassis and racks.
  • Space Optimization: Helps manage cables efficiently, reducing clutter and improving organization.

How to Measure Quarter Turn Fasteners

Measuring quarter-turn fasteners involves four dimensions: upper plate as well as receptacle thickness, space beneath the plate and Hheight above the plate. 

  • Upper plate and receptacle thickness: This refers to the thickness of the clamped upper and lower tabs, which is necessary to assess whether the quarter turn fasteners’ elastic preload is sufficient.
  • Space beneath the plate: It had better to make sure there’s enough room below the plate to prevent the pin from scratching other parts when pressing down the quarter turn. 
  • Height above the plate: The vertical space above the plate is used to ensure the space required for installing the quarter turn fasteners is reserved.

The size and color of Fivetech’s Quarter Turn Fasteners can satisfy every special requirement. If stronger locking force is required in the design and frequent disassembly is not anticipated, our Captive Screws are also recommended for use.
