This is a heavy-duty pelican hook (a type of quick-release clip) made from marine-grade 316 stainless steel, so it resists rust and corrosion even in salty environments. It has a 5/16\ UNF internal thread, which is common for securing lines, cables, or chains on boats. Mainly used on ships to secure gates in guardrails while keeping the tension tight – you can quickly release it if needed. Dimensions are roughly: A=16mm, B=97mm, C=13mm, D=8mm. Weighs about 0.11kg. It’s strong, reliable, and built to last. Great for marine applications, but also handy for any situation where you need a secure, quick-release connector.
