Total ½” x 21mm Deep Hexagonal Socket

Total ½” x 21mm Deep Hexagonal Socket

The Total ½” x 21mm Deep Hexagonal Socket (Model THTST12213L) is an essential specialized solution for mechanics and industrial technicians who frequently deal with recessed or protruding fasteners. Unlike standard sockets that may bottom out on long-threaded rods, this deep-well version provides a full 76mm of clearance. This allows for safe, efficient torque delivery in cramped or deep-seated environments where a standard tool configuration would be insufficient.

Crafted to rigorous Industrial standards, this socket is forged from high-performance Chrome Vanadium (Cr-V) steel. This material selection ensures that the socket maintains its structural integrity under extreme mechanical stress while remaining highly resistant to the oils, grease, and chemicals common in professional workshop settings. The precision-machined 6-point hexagonal internal profile is specifically engineered to grip the flat sides of the bolt head rather than the corners, significantly reducing the risk of slipping or stripping. Whether you are performing a complex transmission repair or routine industrial machinery maintenance, Total’s industrial-grade construction provides the reliability and precision required for professional results.

Key Benefits:

• Superior Accessibility: The 21mm deep profile is ideal for reaching fasteners on long-threaded bolts where a standard socket would be ineffective.

• Industrial Durability: Forged Cr-V construction provides the strength needed for high-leverage professional tasks in demanding environments.

• Universal Compatibility: Integrates seamlessly with your existing 1/2″ drive collection of ratchets, power handles, and torque wrenches.

• Clear Identification: Features high-visibility size markings on the socket body for rapid selection in a busy toolkit.

Perfect For:

• Automotive Technicians: Essential for 21mm wheel nuts, suspension components, and deep-seated chassis bolts.

• Heavy Machinery Maintenance: Servicing specialized production equipment where fasteners are often recessed behind safety guards.

• Construction & Industrial Use: Provides reliable performance on high-torque industrial fasteners.

Application Instructions:

1. Verify the fastener is exactly 21mm before selecting the socket.

2. Press the socket onto the 1/2″ drive end of your ratchet or power bar until it is securely locked.

3. Ensure the socket is fully seated over the bolt head or nut before applying pressure.

4. Apply steady, firm force to loosen or tighten as required.

5. For initial loosening of seized bolts, use this socket with the Tolsen 18″ Power Handle for maximum leverage.

Pro Tips:

• Torque Accuracy: For critical safety components like wheel nuts, always finish the job using a Tolsen 1/2″ Torque Wrench set to exact manufacturer specifications.

• Deep Access: If the bolt is exceptionally deep, combine this socket with a Tolsen 10″ Extension Bar to navigate complex mechanical obstructions.

• Tool Maintenance: Wipe the socket with a clean, slightly oily cloth after use to maintain the polished Cr-V finish and prevent surface oxidation.
