Socket STANLEY STMT86521-0 1/2" drive, imperial sockets, length 94 mm, width 44 mm

STANLEY STMT86521-0 is a 1/2" drive imperial socket designed for use with ratchets and torque tools that accept a 1/2" drive. Forged from chrome vanadium steel with a high chrome finish, the socket offers corrosion resistance and enhanced strength. The 6-point MaxiDrive profile improves engagement with nuts and bolts to reduce slippage, while visible size marking makes fast identification on the bench or in a toolbox. The compact dimensions of 94 mm length and 44 mm width and a weight of approximately 97 g make it easy to handle in general mechanical and maintenance tasks.

Advantages

The chrome vanadium construction and high chrome finish provide reliable durability and resistance to wear and corrosion. The 6-point MaxiDrive profile increases contact area on fasteners, helping to prevent rounding and slippage under load. Visible size markings simplify selection and speed up workflow. Its compact size balances reach and accessibility for work in confined spaces while remaining compatible with standard 1/2" drive tools.

Suitable for

• Automotive repair and maintenance tasks using imperial fasteners
• General mechanical assembly and disassembly where a 1/2" drive is required
• Workshop and field service tasks that need a compact, robust socket
• Use with ratchets and torque wrenches accepting a 1/2" drive

Key specifications

• Socket profile: 6-point MaxiDrive
• Material: chrome vanadium steel with high chrome finish
• Length: 94 mm
• Width: 44 mm
• Weight: approximately 97 g
• Fastener system: imperial sizes

How to use

Select the socket that matches the fastener size, ensuring the 6-point profile fully engages the nut or bolt. Attach the socket to a compatible 1/2" drive ratchet, breaker bar, or torque wrench. Apply force smoothly and steadily to avoid sudden impacts; when using a torque tool, set the required torque value and re-check fasteners after initial tightening. After use, clean off debris and store the socket in a dry environment to maintain the chrome finish.

Usage recommendations

Use this socket with tools rated for the required torque and avoid applying excessive impact loads beyond tool or socket ratings. For optimal grip and reduced fastener damage, align the socket squarely on the fastener and use the 6-point profile rather than crowfoot adapters where possible.
