eWINNER 6 Pack Quarter Inch Male to Male Threaded Tripod Screw Adapters with Hex Wrench, Knurled Aluminium Alloy Converters with Release Hole for Camera Cage and Light Stand - PE-9ZJA-RX51

Link your camera gear together quickly and securely with this six-pack of eWINNER 1/4-20 male to 1/4-20 male screw adapters. Each double-ended adapter is machined from aluminium alloy that resists rust and corrosion, giving a far longer service life than plastic connectors. Deep, burr-free threads and a knurled anti-skid collar let you tighten and loosen by hand with a firm grip. The upgraded design adds a 3.5 mm hole through the middle collar: slide the included hex wrench in and even a tightly fastened screw comes loose with ease. Measuring 16 mm across and weighing only 3.6 g each, the adapters follow the international 1/4-20 standard on both ends, so they connect cameras and accessories to tripods, monopods, ball heads, lens collars and plates, light stands, telescopes, camera cages and shoulder rigs. With six in the pack, you can build several rigs at once and keep spares in your bag.
