The lightweight 80 g pack and retail packaging make it convenient to keep in a toolbox, glove compartment or tool drawer.

Advantages

The sockets feature a 12-point Dynamic-Drive™ profile that reduces wear on screw heads and nuts, extending component life. Both heads swivel 180° for improved access in confined or awkward positions. Manufactured from a high-performance alloy steel with chrome-plated micro-matte finishing, these sockets combine corrosion resistance and a high-quality surface for reliable long-term use. The retail plastic info card pack supports easy storage and quick identification.

How to use

Select the socket matching the fastener size (12 mm or 13 mm), mount it on a compatible ratchet or driver, and engage the fastener squarely to avoid slipping. Use the 180° swivelling heads to reach fasteners in restricted spaces or at awkward angles. Apply steady torque within the recommended limits for hand tools and avoid using excessive force or impact tools unless the socket is rated for such use.

Usage recommendations

Store the socket in a dry place and keep the chrome-plated surface clean to minimize corrosion. Inspect the contact surfaces before use and replace the socket if significant wear or deformation is present. Use appropriate hand tools and follow manufacturer torque recommendations for safe and effective fastening.
