Quarter-turn fasteners are innovative fasteners that allow for a 90-degree rotation during installation, providing numerous benefits compared to traditional bolts in various situations. Designs range from tool-free installations with winged heads or arrow-marked knobs for engagement indication to simpler slotted or Phillips-head recess options. Notably, their spring compliance enhances vibration resistance, ensuring positive locking.

Quarter-turn fasteners, valued for their ergonomic and cost-effective assembly, offer design flexibility in actuation, ejection, stud, and receptacle styles, as well as retention and trim options. Ideal for panel and cover attachment, they streamline initial assembly with snap-in, adhesive-mount, and clip-on components, while also reducing service time for equipment disassemblies and reassemblies. Widely used in aerospace, automotive, electronics, and furniture industries, these half-turn fasteners provide secure, reliable connections for rapid, repetitive assembly and disassembly needs.

At Fivetech, we provide different but better solutions to any turn fastener needs. Here are our quarter-turn fasteners’ top features:

	Tool-free Convenience		Design Flexibility
	Visual Design for Confirmation		Ergonomic Assembly
