Klein 6-in. Magnetic Nut Setters with Case, 12 Pieces (33860)

Key Features
6-Inch Reach
Each nut setter is 6" long, so you can get to recessed and deep fasteners without stacking an extension.
Magnets Sized to the Socket
Premium magnets are tiered by size, so a 9/16" setter holds its fastener as securely as a 1/4" one.
Impact-Rated
Built for impact drivers on the toughest driving jobs, not just drills.
MODbox Compatible Case
All 12 pieces store in a case that connects with other Klein MODbox storage modules.
Overview
The Klein Tools 6-Inch Magnetic Nut Setters with Case, 12-Piece (33860) is a 12-piece set of long magnetic power nut setters for drills and impact drivers. This is a nut setter set designed for fastening hex-head screws, bolts and nuts in facility maintenance, automotive and general assembly work. It covers six SAE and six metric sizes in a MODbox compatible case.
Sizes included: 1/4", 5/16", 3/8", 7/16", 1/2" and 9/16" SAE, plus 7 mm, 8 mm, 10 mm, 12 mm, 13 mm and 14 mm metric. That spread handles the common self-drilling hex screws in HVAC and metal framing work, as well as the metric fasteners on equipment and machinery.
The 6" (15.2 cm) shaft length is the practical difference from standard short setters. It reaches fasteners recessed in channel, behind flanges or deep inside equipment housings, and keeps the chuck of the driver clear of the work surface.
Klein uses high-grade rare-earth magnets that are tiered by size. Rather than one magnet strength across the set, larger setters get stronger retention to match heavier fasteners, so the fastener stays seated on the way to the hole. All setters have a 1/4" hex drive, are made of steel alloy and are impact-rated.
Bright color-coded rings and bold laser-etched size markings make it quick to pick the right setter out of the case. The case is MODbox compatible, so it can be carried on its own or connected with other Klein storage modules. The full set weighs 3.1 lb (1,386 g).
Who should buy it: maintenance techs, HVAC and mechanical installers, metal building and framing crews, automotive and equipment techs, and assemblers who drive a lot of hex fasteners with an impact.
Fasteners Stay Put
Magnets are tiered by size for retention matched to each hex, which means fewer dropped screws into a ceiling or engine bay.

Tool Nut's Take
Long Reach, Strong Grip, Both Standards
The Klein Tools 6-Inch Magnetic Nut Setters with Case (33860) cover the 12 hex sizes most crews drive, with reach to spare.
Who it's for: Maintenance, HVAC and assembly techs who drive hex fasteners with an impact all day.
Why it stands out: Size-tiered rare-earth magnets and a 6" reach in an impact-rated set, stored in a MODbox case.
Worth knowing: Six-inch setters are long for wide-open work. If your fasteners are all in the open, short setters are easier to control.
