Wiha Tools 26539 Precision Nut Driver 5/32 in Sae

Product Description

The WIHA TOOLS 26539 is a solid round shank precision nut driver designed for installing and removing small nuts and bolts in fine assembly and repair work. The alloy steel shank is chrome-finished and machined to tight tolerances, providing a secure fit on 5/32 inch fastener heads and reducing the risk of cam out. The molded plastic handle features a straight profile with a spinning cap that allows fingertip control over rotation and applied pressure. Overall length is 6 inches, making it a compact, purpose-built hand tool suited for electronics technicians, field service pros, and trade professionals working in tight or detail-oriented spaces.

This nut driver is intended for SAE fastener applications requiring a 5/32 inch drive. The slim handle profile and precisely machined tip make it well suited for fine assembly tasks, control board servicing, low-voltage wiring enclosures, and small-fastener repair work across HVAC, electrical, and mechanical service trades. The fixed shank and non-magnetized tip keep the tool straightforward and reliable for repetitive precision work where a minimalist, accurate driver is preferred over feature-heavy alternatives.

Key Features

• Alloy steel shank with chrome finish rated HRC 61-65 for hardness and wear resistance
• Tip machined to tight tolerances for secure fastener engagement and reduced cam out risk
• Spinning cap on handle allows controlled fingertip rotation and precise pressure application
• Fixed, solid round shank construction for direct torque transfer
• Corrosion-resistant finish suitable for varied service environments
• Non-magnetized tip for applications where magnetic attraction to fasteners is undesirable

Compatibility

Designed for use with 5/32 inch SAE hex fasteners. Bolt clearance is 5/16 inch. Suitable for fine assembly and repair tasks across electrical, HVAC, and mechanical service applications requiring a standard precision nut driver.

Installation Notes

De-energize and lock out all electrical circuits before using hand tools in or around live panels or control enclosures, in accordance with applicable NFPA 70E safe work practices. This tool is not insulated and is not rated for live electrical work. Apply steady, controlled pressure through the spinning cap to avoid fastener damage in fine-thread or soft-material applications. Inspect the shank tip before each use for wear that could cause slipping on fastener heads.
