Impact Socket Set Asta A-1Z9S 1/4"–3/8" hex (inch)

The Asta Impact Socket Set A-1Z9S 1/4"–3/8" hex (inch) is a compact collection of impact-rated hex sockets sized for inch fasteners. Designed for use with impact wrenches and pneumatic or electric drivers, the set covers common 1/4" and 3/8" drive applications and is intended for tasks in automotive repair, machinery maintenance, and general workshop work. Sockets are manufactured to withstand the torque and vibration produced by impact tools while providing a secure fit on hex-head fasteners.

Advantages

The set offers impact-rated construction that reduces the risk of cracking or deformation during repeated high-torque use. Individual sockets are machined for consistent hex engagement to minimise rounding of fasteners. The compact range from 1/4" to 3/8" makes the set versatile for both tight-access tasks and standard maintenance jobs. Its compatibility with common impact drivers and wrenches simplifies tool selection for professionals and hobbyists who require inch-size hex sockets.

Suitable for

• Automotive repair and service tasks involving inch hex fasteners
• Maintenance of machinery and industrial equipment using inch bolts
• Workshop repairs and assembly where impact drivers are used
• Home DIY projects requiring inch-size hex sockets

Key specifications

• Socket sizes: inch hex range covering 1/4" to 3/8" applications
• Drive type: compatible with impact wrenches and pneumatic or electric drivers
• Material and treatment: impact-rated construction for high torque use
• Fit: machined hex engagement for secure grip on fasteners
• Intended use: suitable for professional and home workshop environments

How to use

Select the correct socket size for the hex fastener to ensure full contact with the flats of the bolt or nut. Fit the socket onto the impact wrench or driver, ensuring the drive connection is secure. Apply controlled bursts of torque with the impact tool, maintaining a steady hand to prevent slippage; when removing fasteners, start at low power to break initial resistance before increasing torque as needed. After use, inspect sockets for wear or damage and store them in a suitable case or organiser to keep the set complete and accessible.

Usage recommendations

Use sockets only with impact-rated drivers or wrenches and avoid using damaged sockets. Match socket size precisely to the fastener to reduce rounding, and wear appropriate eye and hand protection when operating impact tools.
