Premium 7-Piece Nut Driver Set for Pro-Grade Precision

The Klein Tools 631 Nut Driver Set combines seven commonly used sizes with generous 3-inch hollow shafts, engineered for easy access in tight spaces. Tip-Ident color coding helps you identify the correct hex orientation at a glance, saving setup time on busy days.

Designed for comfort and reliable torque, the Cushion-Grip handles deliver steady control and reduced slip during extended tasks. The chrome-plated shafts resist corrosion while internal flanges create a solid, twist-resistant anchor, so you can trust the tool to stay aligned under steady pressure.

What you get

  • Seven hex sizes: 3/16, 1/4, 5/16, 11/32, 3/8, 7/16, 1/2 inch
  • 3-inch hollow shafts for reaching long bolts and recessed fasteners
  • Tip-Ident color coding on handle ends for quick size orientation
  • Premium USA-made craftsmanship backed by a lifetime warranty

Since 1857, Klein Tools has produced durable, high-precision hand tools. The 631 set embodies that legacy with sturdy construction and practical features designed for repetitive tightening, precise alignment, and dependable performance in electrical, electronics, and mechanical applications. While no tool guarantees outcomes, this set can help you tackle common hex fastener tasks with confidence.

Practical uses and benefits

  • Electrical panel work and appliance installations where exact hex sizes matter

  • Replacements and upgrades in automotive, electronics, and general maintenance projects
