Secure Lock Brass Nipple, 14g/12mm, Silver, 100/Count

Sapim Secure Lock Brass Nipple is a wheelbuilding-ready spoke nipple designed to hold tension more reliably without relying on threadlock compounds. The integrated Secure Lock feature adds controlled resistance at the threads to help prevent gradual loosening from vibration, while still allowing normal truing and re-tensioning with standard tools—useful for hard-used road, gravel, commuting, and MTB wheels.

• Secure Lock mechanical retention - Helps nipples resist backing out over time without paste or liquid threadlocker, simplifying both initial builds and future truing
• Brass construction - Prioritizes durability and corrosion resistance for long-term serviceability, especially in wet or salty conditions
• Polyax head design - Ball-joint style interface helps the nipple align more naturally to the spoke line at the rim bed, reducing point loading and easing tensioning consistency
• 14g / 12mm sizing - Fits standard 14g spokes with a common 12mm nipple length for broad rim and build compatibility
• 100-count pack - Practical quantity for complete wheel builds with spares for future service
• Silver finish - Clean, classic look that matches most spoke and rim aesthetics
