STAINLESS STEEL PEAR SHAPED QUICK LINK is a special-shaped quick release ring designed for high-security connections, forged from 304/316 stainless steel. Its unique pear-shaped structure provides more internal space for connecting thick ropes, multi-strand cables or large hooks, while maintaining the same high strength and easy operation characteristics as traditional quick release rings. It is widely used in scenes that require reliable connection and frequent disassembly, such as sailing rigging, stage hanging, mountaineering equipment and industrial lifting. The 316 stainless steel version is particularly suitable for harsh applications with long-term exposure to seawater or chemical environments.

Special-shaped expansion design: pear-shaped opening provides 30% more storage space than round quick release rings
Military-grade forging process: one-piece molding without welds, 50% higher strength than castings
Dual safety mechanism: thread locking + safety pin hole design (some models)
Fluid mechanics optimization: streamlined contour reduces water flow resistance during navigation
Low temperature tolerance: still maintains toughness at -60℃ (after deep cryogenic treatment)
Sailboat racing: mainsail foresail rigging quick replacement system
High-altitude work: safety rope transition connection for curtain wall installation workers
Performing arts engineering: suspension nodes for LED screens and audio equipment
Industrial rescue: multi-directional force distribution connection in collapse rescue
Military and police equipment: central connection point for tactical climbing and descending systems
Q1: Does the pear-shaped design affect the longitudinal tensile strength?
A: According to finite element analysis, the patented pear-shaped structure has a strength loss of <3% when the axis is stressed, but the lateral stress must be controlled within 15°.
Q3: How to identify counterfeit forged products?
A: The genuine product has a laser-engraved material number (such as "316SS-F") and heat treatment batch number, and the magnetic attraction test should only have weak magnetism.
Q3: What is the standard hole diameter of the safety pin hole?
A: The universal type is 3.2mm (suitable for 1/8" fuse), and the heavy-duty type provides a 5mm double-hole design.
Q3: Can it be used for diving equipment?
A: You need to choose the 316L ultra-low carbon version and perform potential corrosion testing every month. It is recommended to use it with titanium alloy pins.
Q3: What are the measures to prevent the threads from loosening?
A: The high-end model uses NASA standard double threads + nylon locking grooves, and the conventional model recommends using Loctite 243 thread glue.
