Socket 1/2" 12-point 28 mm Hartsson 17C328Z

The Hartsson 1/2" 12-point 28 mm socket is a hand tool attachment designed for use with 1/2-inch drive ratchets and torque wrenches. It fits 28 mm hex fasteners and features a 12-point internal profile that allows engagement at smaller rotation increments. The socket is intended for tasks in automotive repair, machinery maintenance, and general mechanical work where a 28 mm size and 1/2" drive compatibility are required.

Advantages

The 12-point configuration reduces the required swing arc compared with 6-point sockets, making it easier to work in confined spaces. Compatibility with 1/2" drive tools ensures straightforward connection to common ratchets and torque wrenches. The 28 mm size covers a range of large hex fasteners commonly found on engines, suspension components, and industrial equipment. The socket’s design provides repeated positive engagement with fastener corners when used with appropriate torque tools.

Suitable for

• Automotive engine and suspension fastener removal and installation
• Heavy machinery and agricultural equipment maintenance
• Workshop general mechanical and assembly tasks requiring a 28 mm socket

Key specifications

• Drive size: 1/2 inch
• Point profile: 12-point internal
• Nominal socket size: 28 mm
• Typical applications: hex fasteners in automotive and industrial contexts

How to use

Select a compatible 1/2" drive ratchet or torque wrench, attach the 28 mm socket to the tool’s square drive, and seat the socket fully on the hex fastener. Apply turning force with steady pressure; if using a torque wrench, set the required torque and apply force until the wrench indicates the set value. When working in restricted spaces, use the 12-point geometry to reposition the tool with smaller swing angles. Inspect the socket and fastener seating before applying high torque to avoid rounding.

Usage recommendations

Use the socket with tools that match the 1/2" drive size and with torque settings appropriate for the fastener and application. Avoid applying impact-style loads unless the socket is specifically rated for impact use. Store in a dry, organized tool storage to prevent corrosion and to maintain accurate fit.
