The 3/8"-16 Syrp UNC Camera Screw is a plated-steel camera tie-down screw for use with the Syrp 90mm QR plate. The 3/8"-16 is a common screw size that allows you to mount your compatible camera, ball head, or video head with flat base onto the quick release plate so you can mount it on your Syrp Magic Carpet Pro Slider. This camera screw is a perfect replacement for the original screw and is good to have on hand as a spare if your original becomes lost or damaged.
