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.

Key Features

  • 10mm Spline Profile: Six-petal internal recess design for secure engagement with machined bolt heads
  • 3/8-Inch Drive: Standard square drive compatible with ratchets, impact drivers, and torque wrenches
  • Compact Stubby Design: Short profile enables access in tight assembly areas
  • Black Oxide Finish: Corrosion-resistant coating for durability in workshop and field conditions
  • Precision Machined: Tight tolerances ensure consistent, reliable engagement without cam-out
  • Professional Grade: Built for automotive assembly, industrial fastening, and precision mechanical work

Business Advantages for Resellers

  • High-Margin Accessory: Specialty spline sockets command premium pricing compared to standard hex sockets
  • Repeat Sales Potential: Customers typically purchase multiple sizes as they encounter different fastener specifications
  • Professional Positioning: Carrying spline sockets positions your shop as equipped for precision assembly work
  • Bulk Order Appeal: Mechanics and assembly shops often buy in sets; recommend cross-selling with 13mm and larger spline options
  • Loyalty Driver: Specialty tool availability keeps customers returning for hard-to-find items

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.
