Nut Driver Bit HAZET 958-2

The HAZET 958-2 nut driver bit is a compact adapter designed to convert a 1/2" (12.5 mm) hollow square drive to a solid 3/8" (10 mm) square output. Chrome-plated and manufactured in Germany to DIN 3123 / ISO 3316 standards, the bit measures 36 mm in total length and weighs approximately 0.06 kg, providing a durable, corrosion-resistant connection for socket and driver tools.

Advantages

The adapter features a locking ball for secure retention of sockets and accessories and a chrome-plated surface for wear and corrosion resistance. Conformance to DIN 3123 and ISO 3316 ensures dimensional accuracy and compatibility with standard square-drive tools. Its compact 36 mm length and lightweight construction make it convenient for use in confined spaces and for portability.

Suitable for

• Converting 1/2" (12.5 mm) hollow square drives to 3/8" (10 mm) solid square outputs
• Use with ratchets, impact drivers (where appropriate), and hand-held socket drivers
• Tight spaces and general mechanical, automotive, and maintenance tasks

How to use

Insert the 12.5 mm (1/2") hollow square end onto the corresponding driver or ratchet until the locking ball engages. Attach a 10 mm (3/8") socket or accessory onto the solid square output until it clicks into place. Operate the tool as required, taking care to match torque and tool type to the adapter's specifications to avoid overstressing the bit.

Usage recommendations

For safe and long-lasting performance, use the adapter with compatible hand tools and avoid excessive impact torque unless the adapter and the driving tool are rated for such use. Keep the chrome-plated surface clean and lightly lubricated if exposed to corrosive environments.
