Klein Tools 80021 Tool Set Screwdriver and Nut Driver Kit - Built

Our review of the Klein Tools 80021 tool set finds it best suited for homeowners, electricians, and tradespeople who need a dependable, all-in-one hand tool kit. The biggest reason to buy is the combination of useful, commonly used screwdriver tips and fully hollow nut drivers plus a powerful magnetizer/demagnetizer, which together make everyday fastening and long-bolt work faster and less fussy. The set balances durability and value by offering chrome-plated, heat-treated components and tools manufactured and assembled in the USA.

Key Features

• 16-piece assortment: Includes eight screwdrivers and seven hollow nut drivers that cover the most common sizes for home and trade tasks, reducing trips to the toolbox.
• Fully hollow nut drivers: Each nut driver has a 3-in fully hollow shaft to reach long bolts and threaded rods without needing extensions.
• Magnetizer/demagnetizer: The single-swipe magnetism uses rare-earth magnets to quickly magnetize or demagnetize screwdriver tips for faster screw placement and easier removal.
• Tip-Ident: Nut drivers feature Tip-Ident markers for quick visual size recognition on the job, saving time when switching tools.
• Durable finish: Heat-treated, chrome-plated components provide corrosion resistance and extend the life of the tools under regular use.
• Made in USA: Manufactured and assembled in the United States, offering consistent quality control and parts provenance.

Who It's For

This kit is ideal for homeowners who do regular repairs and upgrades, electricians and technicians who need a compact set for daily service work, and hobbyists who appreciate durable, USA-made hand tools. The included sizes and magnetizer make it practical for tasks from cabinet hardware to light electrical work.

Those who should look elsewhere include professionals needing specialty bits, insulated screwdrivers for live electrical work, or larger industrial socket sets; the 80021 focuses on common screwdriver and nut driver sizes rather than every possible fastener type.
