The Neewer UA001 Screw and Hex Key Storage Plate helps keep your spare screws organized and easy to get out. It comes with a total of 24 screws of six types: two 3/8", six 1/4", four M2.5, four M3, four M4, and four M5 screws, a selection common to cameras and gear and accessories. Four L-shaped hex keys (2.5mm, 3mm, 4mm, 3/16") and a double-ended screwdriver can securely fasten screws in their own threaded holes, and the hex keys magnetically attach to the plate, so you don't lose them. The storage plate can store up to 30 screws and arrange them neatly according to the thread size.
