01TOOL SOCKETS
Precision in every spline
A compact array of ten sockets rests within a structured blue case, each piece secured in its own slot. The arrangement suggests order and readiness, a collection prepared for the demands of mechanical precision rather than casual storage.
Designed for automotive, industrial, and DIY applications, this set covers M4 through M18 spline sizes. It suits professionals and enthusiasts who require consistent torque transfer and resistance to wear under heavy use.


02MATERIALS
Chrome steel forged for hardness
Each bit is constructed from high-quality chrome steel, a material chosen for its inherent strength and longevity. The manufacturing process includes a rigorous quenching treatment, which enhances the metal’s hardness and improves its ability to resist wear over time. This foundational treatment ensures the sockets maintain their structural integrity even when subjected to repetitive or demanding mechanical tasks.

04VERSATILITY
Three drives, ten spline sizes
The set spans M4 to M18 spline sizes, distributed across 1/4 inch, 3/8 inch, and 1/2 inch drive configurations. This variety allows the user to match the tool to the specific fastener and ratchet required, whether working on delicate components or heavier industrial machinery. The comprehensive range eliminates the need for multiple separate sets for common spline applications.
05STORAGE
Securely held in a molded case
The ten pieces are stored in a sturdy, blue blow-molded case. Dedicated slots hold each socket firmly in place, preventing them from shifting or becoming lost during transport. The construction offers excellent shock absorption and drop resistance, protecting the internal components from impact while maintaining an organized layout for easy access.

Important Notes
This product does not contain a lithium battery. Always use the correct size socket for the fastener to prevent damage to the socket or fastener head. Ensure the socket is fully seated on the drive tool before applying torque. Do not use impact tools with these sockets unless they are specifically rated for impact use. Keep tools clean and dry to prevent corrosion. Product packaging may vary slightly in appearance. Manual measurements may have minor errors; refer to the actual product for precise dimensions.
