21/23mm Deep Socket Set — 1/2-Inch Drive, 12-Point Design
Tackle any fastener with confidence using this heavy-duty 21mm & 23mm Deep Socket Set.

Key Features
- Chrome Vanadium Steel Construction: Heat-treated for maximum toughness, resisting wear and deformation even under heavy torque loads.
- 12-Point Design: Provides a precise, secure grip on fasteners, enabling optimal torque application and significantly reducing the chance of rounding off bolt edges.
- Deep Socket Profile: Ideal for reaching recessed or deeply seated nuts and bolts that standard sockets simply can't access.
- Stamped Size Markings: Each socket is clearly stamped with its size for instant, at-a-glance identification — no more guessing in your toolbox.
- Pinhole Locking Design: A built-in pinhole accommodates a locking pin for enhanced stability and security when applying strong torque, helping prevent slippage during operation.
- 1/2-Inch Drive Compatibility: Fits standard 1/2-inch drive ratchets, breaker bars, and torque wrenches for versatile use.
- Multi-Purpose Use: Perfect for automotive repairs, machinery maintenance, DIY home projects, and professional workshop tasks.

Frequently Asked Questions
Q: What sizes are included in this deep socket set?
A: This set includes two deep sockets — a 21mm and a 23mm — both featuring a 1/2-inch drive and a 12-point design for versatile fastener compatibility.
Q: What material are these sockets made from?
A: These sockets are made from heat-treated chromium-vanadium (Cr-V) steel, which provides excellent strength, toughness, and resistance to wear, making them suitable for both professional and home use.
Q: Will these sockets work with my existing ratchet wrench?
A: Yes — these sockets feature a standard 1/2-inch square drive, meaning they are compatible with any 1/2-inch drive ratchet, breaker bar, or torque wrench.
Q: What is the advantage of a 12-point socket over a 6-point socket?
A: A 12-point socket offers more engagement positions (every 30°), making it easier to position on fasteners in tight spaces. It is ideal for general use, though a 6-point socket may be preferred for very stubborn or corroded fasteners where maximum grip is needed.
Q: Why do these sockets have a pinhole?
A: The pinhole design allows you to insert a locking pin (hitch pin or retaining pin) to secure the socket to the drive, preventing it from accidentally detaching when applying strong or sustained torque — especially useful in demanding applications.
