Socket STANLEY STMT86509-0, 1/2" drive, Imperial socket, length 94 mm, width 44 mm

STANLEY STMT86509-0 is a 1/2" drive Imperial socket designed for use with inch-based bolts and nuts. Forged from chrome vanadium steel with a high chrome finish, the socket provides corrosion resistance and mechanical strength. The tool is compact and lightweight (51 g) with overall dimensions of 94 mm length and 44 mm width, and incorporates a 6-point MaxiDrive profile to improve contact with fasteners and reduce slippage. Size marking is visible on the socket body for quick identification during work.

Advantages

The chrome vanadium construction and high chrome finish combine to resist corrosion while maintaining structural durability under repeated torque. The 6-point MaxiDrive profile increases the contact area on hexagonal fasteners, lowering the risk of rounding edges. A compact length and modest weight make the socket easier to handle in confined spaces and during prolonged use. Clear size markings allow fast selection of the correct socket when working with Imperial fasteners.

Suitable for

• Tightening and loosening inch-based bolts and nuts in mechanical assemblies
• Maintenance and repair tasks on vehicles and machinery that use Imperial fasteners
• Work in workshops, garages, and on-site service jobs where a 1/2" drive socket is required
• Situations needing a medium-format socket with improved grip to reduce fastener slippage

Key specifications

• Drive size: 1/2"
• Profile: 6-point MaxiDrive
• Material: chrome vanadium steel with high chrome finish
• Length: 94 mm
• Width: 44 mm
• Weight: 51 g
• Intended fastener system: Imperial (inch) bolts and nuts

How to use

Select the socket matching the nominal inch fastener size printed on the socket. Fit the socket onto a compatible 1/2" drive ratchet, breaker bar, or torque wrench. Place the socket squarely over the fastener head, ensuring full seating of the 6-point profile to minimize rounding. Apply steady torque in the required direction to tighten or loosen the fastener, taking care not to exceed the torque rating of the driver or the fastener. After use, clean off debris and store the socket in a tool organizer to protect the finish.

Usage recommendations

Use the socket with a 1/2" drive tool that matches the intended torque range and avoid excessive impact on the chrome finish. For best results on worn or rounded fasteners, ensure full engagement of the 6-point profile and consider using penetrating lubricant before attempting removal.
