Socket bit 1/2" 13 mm Hartsson 6-point (17A313Z)

Hartsson 6-point socket bit with a 1/2" drive and a 13 mm head (model 17A313Z) is designed for reliable fastening and loosening of hex-head bolts and nuts. The 6-point configuration provides full-face contact with fasteners to reduce rounding and improve torque transfer. This socket bit is compatible with 1/2" ratchets, torque wrenches and impact adapters, making it suitable for automotive, mechanical and general maintenance use where a durable 13 mm socket is required.

Advantages

The 6-point geometry ensures even distribution of force across fastener faces, minimizing the risk of damage. A robust 1/2" drive interface offers compatibility with common workshop tools, allowing accurate torque application and secure engagement. The compact 13 mm size covers a frequently used metric dimension, providing a balance between access in confined spaces and sufficient contact area for high-torque operations.

Suitable for

• Automotive engine and chassis repairs requiring 13 mm sockets
• Mechanical assembly and disassembly of machinery and equipment
• Maintenance tasks using 1/2" drive ratchets, torque wrenches or impact adapters
• Workshops and service garages where durable metric sockets are needed

Key specifications

• Drive size: 1/2" (square drive)
• Head size: 13 mm
• Point configuration: 6-point (hex)
• Intended use: fastening and loosening hex-head bolts and nuts
• Compatibility: designed for use with ratchets, torque wrenches and impact adapters

How to use

Select the 13 mm Hartsson 6-point socket and attach it securely to a 1/2" drive ratchet, torque wrench or impact adapter. Place the socket fully over the hex fastener, ensuring full-face contact before applying torque. For tightening, apply steady, controlled force until desired torque is reached; for loosening, apply reverse rotation while maintaining alignment to prevent slippage. Inspect the socket and fastener for wear or damage before use and replace if deformation is visible.

Usage recommendations

Use this 6-point socket for fasteners in good condition to maximize contact and minimize rounding. When precise torque is required, use a calibrated torque wrench and avoid impact tools unless the socket is specifically rated for impact use. Keep the socket clean and store in a dry tool case to prevent corrosion and maintain reliable fit.
