Product Description
Brief Overview
This 10mm spline socket is purpose-built for machined and secured bolt applications where standard hex sockets fail to grip securely. The multi-lobed internal profile engages specialty bolt head designs, preventing slippage and rounding. The compact 3/8-inch drive design makes it ideal for confined spaces and precision assembly work. Distributors can expand their inventory with complementary options like 11mm spline sockets or complete spline socket sets to serve a broader customer base.

Application & Value Proposition
This socket fills a critical gap in any professional toolkit. Standard hex sockets often slip on machined bolt heads, causing frustration and tool damage. The spline profile provides positive engagement, making it essential for precision work in automotive assembly, industrial fastening, and equipment maintenance.
For distributors, this represents a straightforward value add: a specialty tool with clear customer need and minimal inventory complexity. Stock it alongside your existing socket range and highlight it in marketing to assembly shops and precision mechanics.
