Klein Tools is getting into the wire nut business. The Illinois tool maker, better known for pliers and screwdrivers than consumables, has listed a full line of twist-on wire connectors on its site, all marked “coming soon.”
It is a notable move. Klein has spent years pulling electricians deeper into its ecosystem with hand tools and storage, and connectors mark its first run at a market that Ideal Industries has owned for decades.
Launch coverage includes both standard winged connectors and skirted versions.
Assortments include a 250-pack (APWC250), a 25-pack (APWC25), red 100-packs (RWC100), tan 100-packs (TWC100), blue 25-packs (BWC25), and a 300-pack skirted mix (APSC300).
Specs list four color-coded sizes in the standard line, covering wire ranges from 22 AWG signal wire up to 6 AWG feeders.
A Hex Top Changes How You Install Them
What separates these from the bin at the supply house is the drive. Each connector has a hex-shaped top, so you can run them in with a nut driver or a power tool accessory instead of twisting by hand.
Klein’s own product copy confirms it: “The hex top is compatible with nut drivers and power tool accessories.”
That matters on panel work and production wiring, where spinning a few hundred connectors by hand wears out fingers.
Specialty twist tools exist, like Ideal’s Spin-Twist, but they demand carrying a dedicated driver in the pouch. A connector that takes any 1/4-inch or 5/16-inch nut driver skips that problem entirely.
Klein’s spec sheet also calls out curved wings for leverage on stiff wire combinations, a quick-bite spring that spans wide ranges (yellow 18-10, tan 22-8, red 22-6, blue 14-6), polypropylene shells, and UL listing to 600V.
Skirted versions add a deep wire-entry skirt that covers exposed conductor, which inspectors tend to like in junction boxes.
Why Klein Is Doing This Now
Klein has been expanding hard beyond pliers. The brand recently launched a hand tool line at Lowe’s, dropped a limited-edition Blackout collection, and refreshed its pliers wrench line with grooved jaws.
Connectors are a logical next step. They are cheap, they get reordered constantly, and every connector that lands in a wall is a brand reminder for the next 40 years.
The open question is who stocks them. Ideal has been the default wire nut at supply houses and big boxes for years, and Lowe’s already carries Klein hand tools.
If Lowe’s shelves Klein connectors next to Ideal’s, that shelf space fight gets interesting. For now Klein has not announced pricing, retail partners, or a ship date. We will update when that changes.
What we know for sure: the products are listed on Klein’s own site as coming soon, the SKUs and specs are published, and the hex-top design is confirmed. Pricing has not been announced yet.
Electricians weighing the switch can also look at Milwaukee’s USA-made wire stripper, part of that brand’s own push into the electrical consumables aisle.
