Durable, quality build: made with professional manufacturing processes to ensure consistent fit and long-term functionality. Main features Camera mounting screw: standard 1/4-inch thread for secure attachment to camera or lens bottom ports. D-ring screw: allows direct installation of various plate types into a camera base using 1/4-inch screws and monopod mounting screws; D-ring makes hand tightening straightforward. Monopod compatibility: screw sizes and design match common DSLR monopod and tripod standards so plates and camera bodies mount correctly. Tool or hand install: screws can be tightened by hand using the D-ring or with a screwdriver for a firmer connection. Compatibility and specifications Thread size: 1/4-inch standard camera screw (fits common camera/lens threaded holes and plate mounting points). Intended use: camera base plate mounting, monopod/tripod plate attachment, camera-to-adapter/converter fastening, on-the-go screw replacement. Installation options: hand-tighten via D-ring or use a screwdriver for additional torque. Typical use scenarios Event or travel photography: quickly attach your DSLR to a monopod or quick-release plate for fast setup and teardown between shots. Gear assembly and upgrades: install different base plates or converters directly into the camera base using the D-ring screw and 1/4-inch interface. Field repair or spare part: replace a lost or damaged mounting screw under field conditions using the hand-friendly D-ring design for immediate reuse. Practical notes Align the screw with the camera or plate thread before tightening to avoid cross-threading. Hand-tighten the D-ring for most uses; use a screwdriver for added security but avoid excessive torque. Confirm compatibility with any third-party plates or adapters by checking for a 1/4-inch threaded mounting hole. This set of camera mounting screws and D-ring screw provides a reliable, compatible and easy-to-use solution for attaching cameras, plates, monopods and converters that use standard 1/4-inch threads.
