Socket Bit (6‑point) 1/2" 20mm — Dedra 16A320

Dedra 16A320 is a 6-point socket bit with a 1/2" square drive and a 20 mm hex head designed for secure engagement with hex fasteners. It is intended for use with compatible 1/2" ratchets, torque wrenches and impact handles. The socket bit is built for general workshop use, mechanical repairs and component assembly where reliable torque transfer and precise fit on fasteners are required.

Advantages

The 6-point geometry provides maximum contact with fastener flats, reducing risk of rounding and improving torque transfer. A 1/2" drive ensures compatibility with a wide range of hand tools and workshop equipment. The 20 mm head size covers common bolt and nut dimensions in automotive and industrial applications. Durable construction ensures resistance to routine wear in maintenance and assembly tasks.

Suitable for

• Automotive repairs and maintenance
• Mechanical assembly and disassembly
• Workshop and garage general-purpose fastening
• Use with 1/2" ratchets, torque wrenches and impact handles

Key specifications

• Drive size: 1/2" square drive
• Head profile: 6-point (hex)
• Head size: 20 mm
• Intended use: hand and impact fastening tools
• Typical applications: automotive, mechanical, maintenance, assembly

How to use

Select a compatible 1/2" drive tool and attach the socket bit securely to the tool's square drive. Align the 20 mm hex head with the fastener and apply steady torque, ensuring correct seating to avoid slipping. For torque-critical applications use a calibrated torque wrench and follow the manufacturer's torque specifications. Inspect the bit for wear or damage before use and replace it if the contact surfaces are rounded or deformed.

Usage recommendations

Use the socket bit with tools rated for the intended application: prefer hand ratchets or torque wrenches for controlled torque and impact-rated handles for high-torque rapid loosening. Store in a dry tool chest to limit corrosion and keep the contact faces clean to maintain a secure fit on fasteners.
