Socket Bahco 7800SM-17 Standard Length 1/2 inch Square Drive

The BAHCO 7800SM-17 Standard length 1/2" square drive socket is a metric socket designed for general-purpose fastening and maintenance tasks. With a compact 38 mm length and a 1/2" (12.7 mm) square drive interface, the socket provides a balance between access in confined spaces and sufficient engagement for torque transfer. Constructed for repeated use, it is suitable for workshop, automotive and household tool kits where a reliable metric socket is required.

Advantages

This standard-length socket combines a precise fit for metric fasteners with a robust construction that resists wear during frequent use. The 1/2" square drive enables compatibility with a wide range of ratchets, extensions and torque tools. Its compact 38 mm body improves access in tighter spaces compared with longer sockets while still providing adequate gripping surface on fastener heads. The socket's weight and dimensions make it easy to handle and store within standard socket sets.

Suitable for

• General automotive repairs and maintenance
• Workshop assembly and disassembly of machinery
• Home improvement and DIY fastening tasks
• Use with 1/2" drive ratchets, extension bars and torque wrenches

Key specifications

• Drive size: 1/2" (12.7 mm) square drive
• Length: 38 mm (standard length)
• Designed for: metric fasteners
• Weight: 72 g
• Construction: hardened tool steel (finished for durability)

How to use

Select the socket that matches the metric fastener size and attach it securely to a compatible 1/2" square drive ratchet, breaker bar or torque wrench. Ensure the socket fully engages the fastener head before applying torque. When loosening or tightening, apply smooth, controlled force and avoid sudden impacts unless using an impact-rated socket. After use, clean debris from the socket bore and store it in a socket tray or organizer to prevent corrosion and maintain fit accuracy.

Recommendations

Use the socket with tools rated for the required torque and avoid excessive force beyond recommended limits for your fastener and drive tools. For repeated high-torque or impact applications, consider using sockets specifically rated for impact use. Regularly inspect the socket for wear or rounding and replace if any deformation is visible to maintain safe and accurate operation.
