Total THTST12213L 1/2″ Deep hexagonal socket 21mm

Total THTST12213L is a 21 mm deep hexagonal (6-point) socket with a 1/2″ square drive, engineered for accessing elongated studs, recessed bolts, and deep-seated nuts in high-torque mechanical and automotive applications.

Key Specifications & Features

Primary Uses & Benefits

• Deep Recess & Long Stud Clearance: The 77 mm deep profile allows threaded studs or long bolts to pass through the socket head while still engaging the nut (ideal for suspension components, exhaust hangers, and structural U-bolts).

• High-Torque Hexagonal Engagement: The 6-point design grips the flat sides of fasteners rather than the corners, drastically reducing the risk of stripping or rounding under heavy manual torque.

• Cr-V Durability: Heat-treated Chrome Vanadium steel handles continuous manual loading when paired with 1/2″ ratchets, breaker bars (like the THTFX12151), or L-handles (THLHD12121).
