Klein Tools 65456 Hollow-shaft Nut Driver Set 6 Piece Sae

Product Description

The KLEIN TOOLS 65456 is a 6-piece color-coded hollow-shaft nut driver set built for trade professionals who work with threaded rods and unlimited-length bolt applications. The fully pass-through hollow shaft design eliminates bottoming out, allowing drivers to seat completely on any bolt length. Cold-forged alloy steel construction delivers the strength needed for heavy-duty torque applications, and a wrench-assist flat on the handle shaft gives added leverage when breaking loose stubborn fasteners. ASME color-coded dome stamps on each driver allow fast size identification without reading the label. Cushion-grip polypropylene handles measure 4.3 to 5 inches in length for a comfortable, controlled grip during extended use.

This set is designed for HVAC technicians, electricians, plumbers, and general trade professionals who regularly drive nuts onto threaded rods, conduit supports, equipment mounting hardware, and similar fasteners. The SAE hex drive sizes range from 1/4 inch through 9/16 inch, covering the most common fastener sizes encountered in mechanical and electrical rough-in work. The hollow shaft is especially practical in panel and equipment installations where fasteners run long and standard nut drivers cannot fully engage.

Key Features

• Fully pass-through hollow shaft allows nut driving on threaded rods of unlimited length without bottoming out
• Cold-forged alloy steel construction provides high torque capacity and long service life
• Wrench-assist flat on shaft enables use of an open-end wrench for added torque on stubborn fasteners
• ASME color-coded dome stamps on each driver for fast size identification at a glance
• Cushion-grip polypropylene handles sized 4.3 to 5 inches for comfortable extended use
• 6-piece SAE set covers 1/4, 5/16, 3/8, 7/16, 1/2, and 9/16 inch hex sizes

Compatibility

Designed for use with SAE hex fasteners in the 1/4 to 9/16 inch range. Suitable for nut driving applications on threaded rods and standard hex nuts encountered in HVAC, electrical, and mechanical installations.

Installation Notes

This set is not insulated and should not be used on or near energized electrical conductors. Electricians and HVAC technicians should de-energize and lock out equipment before using hand tools in panel enclosures or equipment cabinets. The wrench-assist flat is intended for additional torque with an open-end wrench only — do not use impact tools with these drivers. Store in the included holder to protect shaft tips and maintain organization.
