The professional ASTA 524227 12-point socket features a 1/2" drive square and a 27 mm size, engineered for working with heavy-duty, high-stress fasteners. This tool is widely used when servicing suspension components, axle nuts, steering parts, transmission assemblies, and cup-type oil filters on passenger cars and commercial vehicles.
The expanded 12-point (Bi-Hex) profile doubles the number of contact points with the fastener compared to 6-point alternatives, making it easy to position the socket in confined engine bay or wheel arch areas with a minimal tool swing angle. Forged from high-strength chrome-vanadium steel, the socket resists deformation and is built to transmit extreme torque.
Key Features
- 12-Point Profile (Bi-Hex): Simplifies fitting the socket onto bolts and nuts in restricted spaces while reducing the risk of rounding off edges.
- 1/2" Drive Square: Ensures full compatibility with standard ratchets, breaker bars, and torque wrenches.
- Professional Strength: Hardened alloy steel (Cr-V) withstands intensive mechanical stress without wall breakdown.
- Anti-Corrosion Finish: Mirror chrome plating reliably protects the tool from rust, oils, and aggressive workshop fluids.
- Optimal Clearance: Allows for efficient work on fasteners mounted on protruding threaded studs.
