Environmental protection material watch bolt auricular needle spring shafts in six sizes from 21mm to 26mm

This product is a bulk supply of functional watch accessories parts designed for replacing the pins and spring shafts that secure watch bands to watch cases. Offered in a substantial quantity of 200,000 pieces per box, it is geared towards professional watch repair services, maintenance workshops, or serious hobbyists who require a high volume of consistent, reliable components. The key specification is the availability across six distinct length measurements: 21mm, 22mm, 23mm, 24mm, 25mm, and 26mm. This range covers a spectrum of common watch band thicknesses and lug designs, allowing technicians to match the pin length precisely to the watch model being serviced. The material is identified as an environmental protection material, which is the primary stated characteristic regarding its composition and manufacturing consideration.
Features and Construction

The core features of these watch accessories parts revolve around their measurable specifications and practical application. As a combined bolt, auricular needle, and spring shaft unit, each piece is a complete replacement component for the mechanism that holds a watch band in place.
Material and Build
The construction uses an environmental protection material. This is the sole material detail provided, indicating a specific choice in its production. The part is designed as an integrated unit, combining the functions of a bolt, an auricular needle (likely referring to a pin or post), and a spring shaft into one replaceable component. This integrated design aims to simplify the replacement process, as a single piece restores the band attachment function.
Size and Practical Fit
The product's most concrete feature is its availability in six exact lengths: 21mm, 22mm, 23mm, 24mm, 25mm, and 26mm. These measurements are critical for correct installation, as a pin that is too long will protrude uncomfortably, while one that is too short will fail to secure the band properly. Having this range available in bulk allows a repair service to efficiently service a wide variety of watch brands and models without needing to source multiple different part numbers, streamlining inventory and reducing service time.
Uses and Placement

These spring shafts have a clear, specialised use in watch maintenance and repair. Their primary function is to serve as a direct replacement for the original pins in a watch band's attachment system.
Event or Professional Use
In a professional watch repair or jewellery workshop setting, this 200,000-piece box represents a cost-effective and efficient stock solution. The large quantity ensures a long-lasting supply, reducing the frequency of reordering and the associated administrative time. For businesses servicing high volumes of watches—such as mall kiosks, dedicated watch repair shops, or even watch manufacturers' service centres—having a reliable, bulk source of a commonly replaced part like a spring shaft is a practical operational decision. The six-size range further enhances this utility by covering many standard watch sizes.
Everyday Home Use
For the dedicated watch enthusiast or hobbyist, a smaller quantity drawn from this bulk pack can be useful for personal watch collection maintenance. It allows for the replacement of lost or broken pins on favourite watch bands without the need to visit a specialist. The availability of specific sizes means the user can measure their watch's original pin or the band's channel and select the matching length from the available options for a correct fit.
Benefits and Buying Value

The value of this product lies in its practicality for specific, high-volume replacement scenarios. It is a functional component sold based on its measurable specifications and quantity.
Reuse and Low Maintenance
As a replacement part, its primary benefit is restoring function to a watch band, thereby extending the usable life of the watch itself. By enabling repair instead of replacement of the entire band or watch, it supports a more sustainable approach to watch ownership. The environmental protection material designation also aligns with this broader consideration of material choice.
Why Choose This Product
This product is chosen for its specific combination of high quantity (200,000 pieces) and multiple size options (six lengths). This makes it distinct from retail packs containing only a few pieces of one size. It is aimed squarely at users whose need is defined by volume and variety, not by single, one-off replacements. The decision is driven by the practical logistics of stocking a repair workshop rather than by aesthetic or luxury considerations.
