NRC&XRC Quick Release Pin Set, 4.5mm
The NRC&XRC package features a pair of stainless steel 316 quick release pins designed for marine or outdoor equipment. The pins are sized at 4.5 mm (3/16 inch) in diameter with an overall length around 50 mm, offering a compact yet sturdy option for securing coupler latches, jack legs, pintle hooks, and related hardware. The corrosion resistance helps prevent rust in damp environments, while the simple release mechanism reduces manual effort during frequent connections and disconnections. Ideal for trailer hitch assemblies and miscellaneous outdoor fixtures.
VTurboWay Quick Release Pin 1/4″ (6.3mm)
Designed for marine hardware and Bimini tops, this 1/4 inch diameter quick release pin is manufactured from marine-grade 316 stainless steel, delivering strong corrosion resistance and durability in harsh conditions. With an overall length of 2.56 inches and a usable length of 2 inches, it provides a reliable pin for deck hinges and supporting poles where quick disassembly is often required. The one-hand release feature makes it a practical choice for boats, trailers, and other mobility-focused equipment where rapid maintenance matters.
Tech Team #00844 Double Wire Lock Pin
The Tech Team pin features a durable steel construction with a yellow zinc dichromate finish for corrosion resistance. It functions as a quick-release replacement for clevis and cotter pin configurations and is suitable for securing hitches, axles, and PTOs on tractors, lawnmowers, and trailers. The single-piece design reduces wear, while the wire lock mechanism simplifies securing and releasing operations, especially in vibration-prone environments where traditional pins may loosen over time.
Begino 4Pcs Linch Pins With Ring
Begino offers a set of four 1/8 inch diameter linch pins with a 1-3/16 inch length and a 1.5 inch quick-release ring. Made from marine-grade 316 stainless steel, these pins resist rust and corrosion in outdoor, saltwater, and dusty environments. The quick-release ring is designed to snap closed with a single hand and stay locked under vibration, enabling fast, secure removal and reattachment without tools. The precise fit reduces wobble and ensures reliable operation in trailers, boats, and various machinery.
Factor 55 Quick Release Hitch Pin
Factor 55 offers a quick release hitch pin suitable for 2″ and 2.5″ hitch receivers. The set includes a cotter pin and is fabricated from high-strength 303+ stainless steel with a grooved head for enhanced grip and ease of handling.

VTurboWay 2 Pack Quick Release Pin, 1/4″ (6.3mm)
This VTurboWay two-pack provides a 1/4 inch diameter quick release pin with a 3 inch overall length and a 2.4 inch usable length. Made from marine-grade 316 stainless steel, these pins offer strong seawater resistance and durable performance for bimini tops, deck hinges, and other marine hardware. The two-pin pack is ideal for spare parts storage, ensuring you have backups ready for frequent maintenance or multiple equipment setups on board or on land.
In each option, the key considerations include corrosion resistance (preferably marine-grade stainless steel), mechanical fit (diameter and usable length), ease of use (quick-release mechanism), and compatibility with existing hardware (clevis, hitch, PTOs, or deck hinges). For marine and outdoor use, prioritize pins with 316 stainless steel and a secure, lockable release mechanism to minimize maintenance needs and downtime.
Buying Guide
- Material and corrosion resistance: Look for marine-grade stainless steel (316) when you expect exposure to saltwater, spray, or humid environments. This reduces rust, pitting, and one-off replacements.
- Diameter and length: Match the pin diameter to your hole size and the usable length to the engagement depth. Misfitting pins can loosen or fail under load.
- Release mechanism: A reliable quick-release or wire-lock system saves time during frequent connections and disconnections. Ensure the mechanism functions smoothly under vibration and wet conditions.
- Head design and grip: Grooved or textured heads improve grip and reduce slipping when wearing gloves. A compact head can fit into tight spaces behind hitch components.
- Compatibility: Verify that the pin is suitable for your specific hardware—hitches, clevis pins, PTOs, or deck hinges. Some pins are designed to replace standard cotter pins, while others are intended for direct installation with built-in locks.
- Maintenance: Look for pins with low maintenance requirements, resistant coatings, and easy-clean surfaces to extend life in dirty or salty environments.
- Spare sets: For vehicles or boats with multiple connections, consider buying a multi-pack to ensure you have on-hand replacements or backups for different applications.
Across these options, the best choice depends on your primary use—trailers and hitch assemblies favor stronger locking and precise sizing, while marine applications emphasize corrosion resistance and ease of operation in wet conditions. By comparing the listed products, you can select a quick release pin that balances performance, longevity, and convenience for your specific setup.
