Hex Extension – Precision Reach and Power for Every Task

Perfect for Builders, Mechanics, Electricians, and DIY Enthusiasts Across New Zealand

When you need extra reach or flexibility in tight or hard-to-access spaces, the Hex Extension is the perfect solution. Built tough for Kiwi tradespeople and DIYers alike, this compact yet powerful tool accessory extends your drill, driver, or wrench to tackle fasteners in awkward or confined areas with ease.

Whether you’re installing fixtures, assembling furniture, or working on vehicles, a quality hex extension gives you the leverage and control you need without losing torque or precision. Reliable, durable, and compatible with most tools in New Zealand, it’s the ideal addition to every toolbox or workbench.

Description – Hex Extension

A hex extension (also called a hex bit extension or hex shank extender) is a tool accessory designed to increase the reach of a drill, screwdriver, or impact driver. It connects to a standard hex shank and holds drill or driver bits securely, allowing users to reach screws, bolts, and fasteners in areas where a standard tool cannot fit.

Made from heat-treated alloy steel or chrome-vanadium (Cr-V) material, hex extensions combine strength, precision, and corrosion resistance. They are widely used in construction, woodworking, automotive repair, electrical work, and machinery maintenance.

The result: smoother work in confined spaces, faster assembly, and greater tool versatility — exactly what every Kiwi tradesperson and DIYer needs.

Construction and Design

• Material: High-grade alloy steel or chrome-vanadium (Cr-V) for durability and torque strength.
  
• Finish: Nickel or black oxide coating for rust and corrosion resistance.
  
• Sizes: Available in multiple lengths — typically 60 mm, 100 mm, 150 mm, and 200 mm — to suit different applications.
  
• Compatibility: ¼-inch hex shank fits standard drills, screwdrivers, and impact drivers.
  
• Locking Mechanism: Strong magnet or ball-detent system securely holds bits during operation.
  
• Precision Fit: CNC-machined ends ensure a snug connection with minimal wobble for stable torque transfer.
  

Compact but tough, each hex extension delivers consistent torque and reliability for the most demanding New Zealand job sites.
