Three chrome-plated mini extensions in transparent case

TEKTON

TEKTON SHA99020 Mini Extension Set 3-Piece

SKU CH-EX0X-T4CTK

Three mini extensions add reach in tight spaces with a corrosion-resistant chrome finish

  • Product colorTransparent
  • Compact reach for tight spots with three drive sizes
  • Clean, corrosion-resistant chrome finish wipes down easily
  • Beveled drive ends guide smoothly onto tools
  • Four detent grooves lock securely to drive tools
  • Spring-loaded ball holds sockets firmly in place

Compact Three-Drive Mini Extension Set

The TEKTON SHA99020 set includes three mini extensions covering 1/4, 3/8 and 1/2 inch drive sizes. Each piece is designed for use in tight spaces where a standard extension cannot fit. They also serve as incremental reach adjusters when combined with longer extensions. The polished chrome-plated finish resists corrosion and wipes clean easily.

Practical Reach and Fit Limits

The 1/4 inch drive extension measures 3/4 inch, the 3/8 inch drive measures 1 inch and the 1/2 inch drive measures 1-1/2 inches. These fixed lengths define the maximum extra reach each piece adds. Beveled drive ends guide the extension onto the drive tool smoothly. Radiused interior corners reduce stress concentrations that can lead to cracking under load.

Upgrade From Improvised Reach Methods

This set replaces the need to jury-rig reach with universal joints or oversized extensions that won't seat in confined areas. The spring-loaded retaining ball locks sockets securely, preventing drops inside assemblies. Four detent grooves give a positive connection to ratchets and breaker bars. The jump is worth it when fastener access is blocked by frame rails, body panels or engine accessories.
