Description

Torx T40 Screwdriver Bit, 8mm Hex Shank, 30mm Length

Brief Overview

This T40 Torx screwdriver bit delivers reliable fastening performance in a compact 30mm format, purpose-built for professional mechanics and assembly technicians. The 8mm hexagonal shank provides secure engagement with standard 1/4-inch hex chucks on cordless drills, impact drivers, and bit holders. The hardened steel construction resists cam-out and stripping, making it an essential stocking item for resellers serving automotive, electronics assembly, and maintenance shops.

For distributors offering a complete Torx range, pair this T40 bit with larger Torx options like T50 and specialized tamper-resistant variants to maximize cart value and customer satisfaction.

Why Distributors Choose This Bit

The T40 size sits at the sweet spot for general-purpose fastening—large enough for robust industrial fasteners, compact enough for assembly work and electronics repair. The 30mm length is practical for most applications without excessive overhang that can cause torque loss or vibration. The hardened steel construction means longer tool life per unit and fewer customer complaints about premature failure.

Stock this alongside smaller Torx profiles (T30, T25) and larger variants (T50, T60) to serve the full spectrum of your customer base. Professional shops typically maintain multiple bits of the same size for continuity during tool rotations.
