Jonnesway 11-point Socket for Truck Brake Caliper Nuts AN040244, 11-point drive

Jonnesway 11-point socket AN040244 is a hand tool designed for use on truck brake caliper nuts. The 11-point engagement profile matches the geometry of many heavy-vehicle fasteners used in brake systems, providing a secure fit that helps reduce rounding and improves torque transfer during loosening and tightening operations. The socket is intended for professional maintenance and repair where reliable contact with caliper nuts is required.

Advantages

The 11-point design offers more contact surfaces than a 6-point profile, allowing easier alignment with worn or slightly damaged nuts and minimizing slippage. Manufactured by a brand known for professional-grade tools, the socket is suitable for frequent workshop use and supports accurate torque application when paired with proper wrenches or torque tools. Its construction provides durability under the higher loads typical for truck brake work.

Suitable for

• Maintenance and repair of truck and heavy vehicle brake calipers
• Workshops and service centers handling commercial vehicles
• Tasks requiring secure engagement with multi-point caliper nuts
• Applications where preventing rounding of fasteners is important

Key specifications

• Drive type: 11-point engagement profile optimized for caliper nuts
• Intended use: truck and heavy vehicle brake caliper fasteners
• Material: tool-grade metal suitable for high-torque applications
• Compatibility: designed to fit common caliper nut geometries used on trucks

How to use

Select a compatible wrench or torque tool with the correct square drive that matches the socket. Place the socket squarely over the caliper nut and ensure full engagement of the 11 contact points before applying torque. For loosening, apply steady force and avoid sudden impacts unless using an impact-rated socket and appropriate impact tools. For tightening, use a calibrated torque wrench and follow the vehicle manufacturer's torque specifications to ensure proper clamp load on the caliper assembly.

Usage recommendations

Inspect the socket and fastener before use. Replace the socket if deformities or excessive wear are visible. Use appropriate personal protective equipment and follow workshop safety procedures. When using on high-torque applications, verify that the socket and driving tool are rated for the required torque to avoid tool or fastener damage.
