Total ½” x 21mm Deep Socket

Total ½” x 21mm Deep Socket

The Total ½” x 21mm Deep Socket (Model THTST12213L) is an essential specialized tool for mechanics and industrial technicians who frequently deal with recessed or protruding fasteners. Unlike standard sockets, this deep-well version provides the internal clearance necessary to fully seat over long-threaded rods, ensuring a safe and efficient transfer of torque in cramped or deep-seated environments.

Crafted to professional 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 found in professional garage settings. The precision-machined 6-point hexagonal internal profile is designed to grip the flat sides of the bolt head, 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 deep profile is ideal for reaching fasteners on long-threaded bolts where a standard socket would bottom out.

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

• Universal Compatibility: Integrates seamlessly with your existing 1/2″ drive ratchets and power handles.

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

Perfect For:

• Automotive Repair: Essential for 21mm wheel nuts, suspension components, and engine mounts.

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

• Construction & Industrial Use: 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 securely locked.

3. Fully seat the socket 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 Precision: For critical safety components like wheel nuts, always finish the job with 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 in greasy environments to maintain the finish and prevent surface oxidation.
