There are many options for Half / Quarter turn fasteners, for instance there is a Half / Quarter turn screw:
A half-turn screw is a type of fastener designed for quick and secure installation or removal with just a 180-degree turn (half of a full rotation). Unlike traditional screws that require multiple rotations to tighten or loosen, a half-turn screw achieves its locking or fastening mechanism in a single, swift movement.
There are also Half Turn Screws available, these are screws that use a wing head instead of the classic hex or flat heads so you don't need a tool to install this screw.
A very popular product is the standard Quarter Turn.
A quarter-turn fastener is a type of quick-release mechanism that locks or unlocks with just a 90-degree (quarter of a full rotation) turn. These fasteners are designed for applications where speed and ease of use are essential.
How It Works:
- Engagement: The fastener aligns with a corresponding slot or insert.
- Locking: A 90-degree turn moves the fastener into a locked position, often with a mechanical or friction-based hold.
- Unlocking: Turning it back 90 degrees releases the hold.
