Nut Drivers

A nut driver is a hand tool with a hollow shaft and fixed-size socket used to tighten or loosen hex nuts and bolts, especially on hardware with short studs and when access is limited; use it for repetitive assembly, electronics, or panel work where a ratchet or wrench is too bulky

Select nut drivers that match the fastener sizes you use most often—sets commonly include metric and SAE sizes; choose individual drivers for occasional use or a set covering a range (e.g., 1/4"–3/8" and 6mm–13mm) for general-purpose work

Compare shaft material and hardness (hardened steel resists wear), handle ergonomics and grip quality for torque comfort, and whether the driver has a magnetic or hollow shaft for passing long bolts; professional options typically offer more durable finishes and better torque transfer

Magnetic tips help hold small fasteners in place, useful for electronics, while hollow-shaft drivers allow you to reach nuts on long threaded studs; choose magnetic for small parts and hollow shafts when studs extend through the nut

Keep shafts clean and lightly oiled to prevent rust, store drivers in a rack or roll to protect tips, avoid using them as pry bars, and periodically inspect for rounded or damaged tips and replace if wear affects fit

Standard hand nut drivers are not designed for power or impact use; if you need powered operation, use sockets and drivers rated for drills or impact drivers that match the torque and attachment system required

Nut drivers typically range from budget options under $20 for single pieces to higher-quality sets averaging around mid-range prices; higher-priced tools generally offer better materials, fit, handle comfort, and longer life, while basic drivers are fine for occasional tasks
