SKU CH-XNTR-GK1C8

Seven-piece magnetic nut driver set with three-inch shafts covering common SAE sizes

  • Magnetic tips hold fasteners securely during use
  • Seven SAE sizes cover common fastener dimensions
  • Three-inch shaft reaches recessed hardware easily
  • Cushion grips reduce hand fatigue on long jobs
  • Trusted Klein Tools quality for professional reliability

7-Piece SAE Nut Driver Set

The Klein Tools 631M set provides seven magnetic nut drivers in SAE sizes covering 3/16 in through 1/2 in. Each driver has a 3 in shank for reach into recessed fasteners. The cushion grip handles reduce fatigue during repetitive use. This new set is aimed at technicians and DIYers who need a compact, organised selection for common hex hardware.

Magnetic Tips Hold Fasteners

The single specification that decides fit is the magnetized tip on every driver, which holds hex nuts and bolts securely during installation or removal. The seven tip sizes match the listed fastener range of 3/16 in, 1/4 in, 5/16 in, 11/32 in, 3/8 in, 7/16 in and 1/2 in. No insulated or ESD-safe rating is present, so the set is not suited for live electrical work.

Fits Standard Tool Storage

The seven-piece count keeps the tray or pouch footprint small, freeing bench space for larger tools. The 3 in shank length clears typical obstructions without the bulk of longer shafts. Buyers needing metric sizes, insulated shafts or a larger piece count will need a different kit. The set ships without a dedicated case, so it integrates into existing organisers.

Questions about this item

What does the 3-inch shaft length mean when I'm working in tight spots?

The 3-inch shaft lets you reach recessed fasteners without the handle hitting surrounding parts, giving extra clearance in engine bays or cabinet interiors.

How does the magnetic tip hold fasteners in practice?

Each driver has a magnetized tip that grabs and holds SAE nuts and bolts from 3/16 up to 1/2 inch, so they stay on the driver while you position them.

What do I need to store or carry these seven drivers?

The set includes all seven SAE sizes in one package; no separate rack or case is required beyond a toolbox drawer or pouch.
