9/16" magnetic nutsetter bit for 1/4" shank drives

The Tuff Stuff NS916250 is a magnetic hex-head nutsetter insert bit built for drills and screwdrivers that accept a 1/4" shank. It targets DIYers, mechanics and maintenance crews who need a single, durable bit for everyday fastening tasks around the house, shop or garage. The magnetic head holds hex nuts and bolts securely during driving.

1/4" shank compatibility decides fit

The only specification that determines whether this bit works with your tool is the 1/4" shank. Any drill, impact driver or screwdriver with a 1/4" hex chuck will accept it directly; tools with a different chuck size or no hex receiver will not. No adapter or sleeve is mentioned in the data.

9/16" hex capacity with 1-7/8" working length

The bit drives 9/16" hex fasteners and provides a 1-7/8" overall length for reach into recessed hardware. It handles common automotive, equipment and structural nuts within that size. It cannot drive smaller or larger hex heads, and the fixed length limits access in very deep or extremely tight cavities where a longer or shorter bit would be required.

Questions about this item

How deep a 9/16" hex nut can the 1-7/8" bit reach in a real machine?

The 1-7/8" overall length lets the magnetic 9/16" socket engage nuts up to roughly that depth from the chuck face, so recessed fasteners within about 1-3/4" are accessible.

What does the 1/4" shank cap in practice for impact or drill use?

The 1/4" hex shank fits any standard quick-change chuck or 1/4" bit holder, limiting torque to what that holder and the bit's steel can handle without rounding.

Will the 9/16" magnetic hex head clear a 1/4" chuck collar when mounted?

Yes — the 1/4" shank seats fully in the chuck while the 9/16" socket protrudes, so the chuck collar sits behind the bit and does not interfere with the nut.
