Jonard Tools ND-631 7-Piece Hollow-Shaft Nut Driver Set
Professional Nut Drivers for Long Bolts, Studs, and Stacked Assemblies
The Jonard Tools ND-631 is a seven-piece nut driver set designed for working with long bolts, threaded studs, stacked circuit boards, and other recessed fasteners. Each driver features a full-length hollow shaft that allows the fastener to pass through the tool while the nut is tightened or removed.
Chrome-vanadium steel shafts provide strength and durability, while ergonomic cushion-grip handles improve comfort, control, and torque during repeated professional use.

Designed for Professional Installers
The ND-631 gives technicians a versatile range of SAE sizes for servicing security equipment, electrical panels, network hardware, control boards, and other equipment that uses hex-head fasteners.
