Sapim Polyax Hexagonal Secure Lock Aluminum Nipple

The patented Secure Lock mechanism uses a specific thread deformation to create friction, which effectively prevents the nipple from vibrating loose over time. This helps maintain consistent spoke tension without needing to rely on thread-locking compounds.

While 7075 aluminum is strong and lightweight, it is generally softer than brass. These are excellent for road, gravel, or cross-country builds where weight savings are a priority, but for heavy-duty downhill or e-bike applications, brass nipples are typically recommended for their superior durability.

The hexagonal head design allows you to use a standard spoke wrench, but it also accommodates a hex-head driver. This makes them much easier to install and true, especially when building wheels with deep-section rims where access can be tight.

Sapim uses high-quality anodizing, which is generally resistant to fading and corrosion. However, like all anodized aluminum, prolonged exposure to harsh environmental conditions or certain cleaning chemicals can eventually affect the vibrancy of the finish.

Yes, these nipples are designed for standard 2.0 mm (14G) spoke threads. They are a direct fit for most standard wheelbuilding projects using standard-gauge spokes.
