Socket Bit Set 1/2" XZN 10-piece — Asta (MPN 954010-1)

Asta 10-piece socket bit set with 1/2" drive and XZN (triple-square) profiles provides a complete selection of sizes for working with fasteners that use triple-square heads. The set is designed for use with 1/2" ratchets, torque wrenches and extensions, allowing firm engagement and accurate torque transfer when servicing automotive transmissions, engines and mechanical assemblies.

Advantages

The set groups ten commonly used XZN sizes in a single compact kit to reduce tool changes and improve workflow. Each bit is shaped to match triple-square fasteners, minimising slip and rounding under load. Compatibility with 1/2" drive tools ensures secure attachment to ratchets and torque wrenches, enabling controlled torque application for maintenance and repair tasks.

Suitable for

• Servicing automotive transmissions and gearboxes
• Engine and drivetrain repairs
• Mechanical assemblies with triple-square fasteners
• Workshop and professional maintenance use

Key specifications

• Drive size: 1/2" compatible
• Bit profile: XZN (triple-square)
• Number of pieces: 10
• Intended use: hand tools — ratchets, torque wrenches, extensions
• Typical applications: automotive and mechanical fasteners with triple-square heads

How to use

Select the correct XZN bit size for the fastener, insert the bit into a compatible 1/2" drive socket or adapter, and attach to the ratchet or torque wrench. Ensure the bit is fully seated in the fastener head before applying torque. For tightening, use a torque wrench set to the manufacturer’s recommended torque; for loosening, apply steady turning force while keeping the bit aligned to avoid cam-out and fastener damage.

Usage recommendations

Store the bits in their case when not in use to protect profiles from damage and to keep sizes organised. Inspect bits for wear or deformation before applying high torque and replace any worn bits to prevent fastener damage. Use appropriate torque settings and correct bit size to maintain fastener integrity.
