Quarter Turn & Half Turn Screws

In stock

Quarter-turn screws lock or unlock with a 90-degree turn, offering fast and easy access, often used for panels in aerospace and automotive. Half-turn screws require a 180-degree turn for engagement, providing a balance of speed and a more substantial feel, also used for quick-access panels and latching mechanisms. The main difference is the rotation needed for operation.
