Quick release pin | A4 | M8374

Quick release pin, quick pin with spring-loaded ball in A4 / AISI 316 stainless steel is intended for use in demanding environments where corrosion resistance and quick handling are required. The product is designed to withstand moisture, salt, chemicals, and significant temperature fluctuations. The design with a spring-loaded ball allows for direct locking in holes without additional locking components, while the pull ring serves as a grip for easy disassembly and adjustment, even in difficult conditions.

AREA OF APPLICATION

The product is used in marine equipment, sailboats, rigging components, docks, and industrial applications. It is intended for applications where quick locking and adjustable fastening of moving parts are required, such as mast adjustment and temporary connections. The design allows for tool-free assembly and disassembly and provides a vibration-proof attachment without the need for nuts or washers.

FREQUENTLY ASKED QUESTIONS (FAQ)

What is a Quick release pin / Quick pin with a spring-loaded ball and how does the locking mechanism work?

A quick release pin (locking pin) is a fast-locking rigging bolt equipped with a spring-loaded detent ball near the end of the pin. When the pin is pushed through a matching hole, the ball is pressed into the pin body. Once it has passed through completely, the ball springs back out and creates an automatic mechanical stop against axial displacement. To remove the pin, you simply pull on the integrated pull ring.

What is the advantage of this design compared to a traditional rigging bolt and cotter pin?

The Quick Pin is designed for applications requiring fast assembly, frequent adjustments, or tool-free disassembly:

• No loose parts: You avoid the need to handle, lose, or bend cotter pins and spring clips.

• Easy handling: The pull ring makes it easy to pull the pin out even when wearing gloves or working in difficult conditions.

• Time-saving: Perfect for temporary rigging, canopy structures, sail fittings, and equipment that frequently needs to be taken down.

Why is acid-proof A4 / AISI 316 crucial for quick pins with a spring-loaded ball?

Since the pin contains internal mechanical components (a spring and a ball), it is especially critical that the material does not corrode. If the spring or the space around the ball is affected by rust, the locking function may cease to work. Acid-proof A4 steel (AISI 316 / 1.4401) provides maximum protection against saltwater, moisture, and chemicals, ensuring that the spring-loaded ball moves freely and maintains its reliable locking function over a long period.
