Carbon Steel Quick Link Used for lifting and connection

Quick Link, also known as Maillon Rapide, screw chain connector, oval connecting ring, thread lock link and chain quick coupler, is an oval load-bearing connector equipped with an integrated threaded opening and hexagonal lock nut that allows users to rapidly connect chains, wire ropes, lifting slings, ropes and fixtures without special tools, and it is divided into two core series including Stainless Steel Light-Duty Quick Link for general rigging, marine and outdoor use and Grade 80 Forged Alloy Steel Heavy-Duty Quick Link certified for industrial overhead lifting and professional rigging; the stainless steel version is available in 304 and marine-grade 316 stainless steel, where 304 stainless steel features polished bright surfaces with reliable rust resistance for indoor and freshwater scenarios such as pet chains, hammocks, farm fencing, tent fixing and light cargo binding, while 316 stainless steel contains molybdenum to deliver outstanding resistance against salt spray and seawater corrosion, making it ideal for yacht rigging, offshore fishing, coastal dock facilities and chemical factory applications, both crafted via hot forging and precise thread machining with smooth rounded edges to prevent rope abrasion and built with a standard 4:1 safety factor meaning the Minimum Breaking Load (MBL) equals four times the Working Load Limit (WLL), covering complete small sizes from M4 (100kg WLL for tent accessories and small hanging items), M6 (220kg WLL for hammocks and swings), M8 (400kg WLL for pet leashes and light binding), M10 (640kg WLL for marine ropes and garden rigging), M12 (880kg WLL for light machinery fixing) to M16 (1600kg WLL for small dock mooring), while the industrial G80 forged alloy steel lifting quick link is manufactured from high-strength 35CrMo alloy steel through drop forging followed by quenching and tempering treatment for superior tensile strength, finished with hot-dip galvanization, black electrophoresis or Dacromet coating for rust protection, fully compliant with EN 1677-1 standards and CE certification with a 4:1 safety factor for lifting slings and a 5:1 safety factor for wire rope rigging, undergoing 100% magnetic particle crack detection and 20,000-cycle fatigue testing under 1.5 times the rated WLL, with standard wire diameter specifications of 6mm (1.12-ton WLL, 4.48-ton MBL for matching 6mm G80 chain), 7mm (1.50-ton WLL, 6.00-ton MBL for 7mm G80 chain), 8mm (2.00-ton WLL, 8.00-ton MBL for 8mm G80 chain), 10mm (3.20-ton WLL, 12.80-ton MBL for 10mm G80 chain), 13mm (8.20-ton WLL, 32.80-ton MBL for 13mm G80 chain) and 16mm (10.00-ton WLL, 40.00-ton MBL for 16mm G80 chain); structurally, every quick link consists of a one-piece forged oval link body as the main load-bearing component, a precision-machined threaded spigot and an anti-slip hexagonal lock nut that can be tightened by hand, though spanner reinforcement and PTFE tape anti-loosening treatment are recommended for dynamic or vibration-heavy working conditions, and the operation steps are straightforward: rotate the hexagonal nut counterclockwise to fully open the threaded end, thread chains, wire ropes or slings through the oval ring cavity, then screw the nut clockwise until it is completely fastened with no exposed threads; this product boasts prominent advantages including far faster assembly and disassembly compared to conventional screw shackles, smooth oval profiles free of sharp corners to avoid abrasion to wire ropes and textile slings, dual material grade options tailored for corrosive environments and heavy industrial lifting, sufficient safety reserve backed by strict 4:1 safety factor and batch destructive testing, full size coverage ranging from tiny M4 light-duty types to large 32mm heavy lifting models to satisfy all rigging matching demands, and clear permanent marking of size, WLL, material grade and manufacturer logo on each unit for full quality traceability, and it serves a wide array of application scenarios: certified G80 forged steel quick links are exclusively permitted for industrial lifting work such as crane chain sling connection, container lashing, machinery hoisting, construction site rigging, port cargo handling and energy & mining equipment fixing, 316 stainless steel quick links are prioritized for marine and offshore operations like yacht mooring, fishing net connection, buoy fixing and permanent coastal saltwater rigging, both series support outdoor and leisure uses including rock climbing auxiliary anchors, hammock and swing suspension, camping tent installation and auxiliary high-altitude fall protection connection, agricultural and livestock applications such as livestock tether chains, greenhouse frame fixation and farm fence assembly, as well as general light rigging work including warehouse hanging point installation, daily cargo binding, pet chain connection and decorative fixture mounting; critical mandatory safety warnings must be followed by all operators: stainless steel quick links are strictly prohibited for overhead lifting tasks, only EN1677-1 CE-certified G80 forged alloy steel quick links can be used for load lifting operations, users must never overload the product beyond its marked WLL and should avoid side pull, point load or uneven angular single-side stress, any welding, grinding, heating or drilling modification to the link body is forbidden as metal damage will drastically reduce its breaking strength, full pre-use inspection for cracks, deformation, thread wear, rust pits and nut slippage is required before every operation with defective pieces discarded immediately, long-term contact with strong acid, alkali and corrosive chemical solvents that degrade metal strength should be avoided, and storage must be arranged in dry, ventilated warehouses with separate storage of stainless steel and carbon steel items to prevent galvanic corrosion, while key professional rigging terminology includes WLL (Working Load Limit, the maximum safe operational load), MBL/MBS (Minimum Breaking Load, the minimum destructive test load) and Safety Factor (the ratio between the minimum breaking load and rated working load).
