3-17mm Double-Head Torx & Hex Self-Tightening Wrench

Compact, self-tightening wrench for Torx and hex fasteners

The 3-17mm Universal Double-Head Torx Wrench is a compact, adjustable hand tool designed to handle a wide range of Torx and standard hex bolts and nuts. Manufactured from chrome-vanadium steel, it offers reliable strength, wear resistance, and dimensional stability for regular use in workshop, automotive, and household settings. The fully polished, plated body helps resist corrosion, while the slim 3.5 mm profile and 160 mm overall length make it easy to access confined or awkward spaces.

This double-head design combines a Torx-compatible jaw on one end with a hex-compatible jaw on the other, reducing the need to switch tools during a task. The integrated self-tightening spring mechanism automatically increases clamping force as you apply torque, helping to minimize slippage and reduce the risk of rounding fastener edges. With an adjustable range from 3 mm to 17 mm, it covers many common sizes used in furniture assembly, machinery maintenance, auto repair, and general DIY work. A textured, non-slip handle area provides a secure, controlled grip, even when hands are oily or when working at difficult angles.

Why It's a Smart Choice

• Wide 3-17 mm adjustment range - One wrench covers multiple Torx and hex sizes, reducing the number of tools you need to carry.
• Self-tightening mechanism - Spring-loaded jaws increase grip under load, helping prevent slipping on stubborn or rusted fasteners.
• Durable chrome-vanadium construction - Corrosion-resistant, impact-tolerant steel suitable for frequent use in professional and home environments.
