Extension Bar 1/2" 250 mm STANLEY 86-408-4 — socket drive accessory

STANLEY 1/2" 250 mm extension bar is a socket drive accessory engineered to extend the reach between a 1/2-inch drive ratchet or breaker bar and sockets. With a 250 mm length, this extension bar enables access to recessed fasteners and confined spaces, improving reach and mechanical advantage for automotive, industrial and maintenance tasks. The accessory is suitable for use with standard 1/2" drive sockets and hand tools where added reach is required.

Advantages

The extension bar provides a straightforward way to reach deep or recessed bolts without modifying surrounding components. Its length reduces the need to reposition tools or disassemble nearby parts, saving time during repair and service operations. The product is compatible with common 1/2" hand tools and sockets, enabling flexible use across different tool sets and work environments.

Suitable for

• Accessing recessed or hard-to-reach bolts and nuts in automotive repair
• Industrial maintenance where extended reach is required
• General workshop and household tasks involving 1/2" drive sockets

Key specifications

• Drive size: 1/2 inch
• Overall length: 250 mm
• Function: extension between drive tool and socket to increase reach
• Intended use: manual socket drive applications with ratchets or breaker bars

How to use

Attach the extension bar to the square drive of a 1/2" ratchet or breaker bar until it locks securely, then fit the appropriate 1/2" socket onto the opposite end. Apply torque evenly and avoid sudden impacts; use steady, controlled force when loosening or tightening fasteners. After use, detach the socket and store the extension bar with other socket accessories to prevent loss or damage.

Usage recommendations

For safe and effective operation, use the extension bar only with compatible 1/2" sockets and hand tools. Do not use the extension bar with power impact tools unless it is specifically rated for impact use. Inspect the connection points before each use and avoid excessive bending or side loads that could damage the tool or fastener.
