Description

Torx TX40 Screwdriver Bit, 1/4-Inch Hex Shank, 50mm Length

Brief Overview

This TX40 Torx screwdriver bit is a precision-engineered driver for high-torque fastening applications. The 1/4-inch hex shank fits standard power drill chucks and quick-change bit holders, while the hardened steel construction delivers reliable performance in demanding industrial environments. For shops requiring flexibility across multiple Torx sizes, consider stocking smaller TX15 variants and extended-length TX30 bits to maximize your inventory versatility.

Key Features

  • TX40 Torx Geometry: Star-shaped engagement with serrated/fluted tip profile for secure engagement and reduced cam-out
  • 1/4-Inch Hex Shank: Universal compatibility with power drills, impact drivers, and quick-change bit holders
  • 50mm Overall Length: Balanced reach for standard assembly and repair work without excessive flex
  • Hardened Steel Construction: Single-piece design resists deformation under high torque loads
  • Retention Groove: Circumferential groove near shank center ensures secure seating in bit holders
  • Industrial-Grade Finish: Matte metallic gray coating provides corrosion resistance

Why This Bit Matters for Your Shop

Torque Reliability: The TX40 size handles mid-to-heavy fastening tasks (electronics assembly, automotive components, industrial machinery). The serrated tip geometry prevents slipping and rounding, reducing customer callbacks.

Bit Holder Compatibility: The 1/4-inch hex drive works with nearly every power tool in your customers' arsenals—from cordless drills to pneumatic drivers. This universal compatibility makes it a high-turnover SKU.

Bulk Order Economics: Torx bits are consumable-adjacent—shops stock them in sets and rotate through them regularly. TX40 is one of the most common sizes for industrial assembly, making this a reliable repeat-purchase item for your retail customers.

Reseller Advantage: Position this as part of a complete TX set alongside other Torx variants. Bundle pricing drives higher basket values and customer retention.
