Torx T40 Driver Bit, 25mm Length, 1/4-Inch Hex Shank

Brief Overview

This T40 Torx driver bit is engineered for professional fastening applications requiring the larger six-lobed Torx profile. The compact 25mm length makes it ideal for confined spaces and precision work, while the 1/4-inch (6.35mm) hex shank ensures compatibility with standard bit holders and impact-rated drivers. Whether you're stocking bits for automotive assembly, electronics manufacturing, or general mechanical service, this size fills a critical gap in professional tool kits. Pair it with smaller Torx options like T20 and T30 sizes or extended-length variants to provide your customers with a complete fastening solution.

Key Features

• Torx T40 Profile: Six-lobed design prevents cam-out and ensures positive engagement with fastener heads
• 25mm Overall Length: Optimized for compact work areas and tight assembly tolerances
• 1/4-Inch Hex Shank: Direct compatibility with quick-change bit holders, hand drivers, and pneumatic impact tools
• Polished Steel Construction: Smooth, corrosion-resistant finish extends tool life in demanding environments
• Precision-Ground Tip: Ensures exact fit and minimizes fastener damage during installation

Why This Bit Matters for Your Business

The T40 profile is a workhorse in automotive electrical systems, industrial equipment assembly, and precision manufacturing. Unlike smaller Torx sizes, T40 handles higher torque loads without slipping, making it essential for technicians who can't afford stripped fasteners or customer callbacks. The short 25mm length reduces inventory complexity—professionals need this specific size without paying for unnecessary shaft length.

Stocking this bit alongside complementary sizes positions your shop as a reliable source for complete Torx solutions. High-volume users (automotive shops, contract manufacturers) will return repeatedly for consistent quality and availability.
