Klein Tools D333-8 – Frequently Asked Questions

1) What size conduit locknuts will the Klein D333-8 pliers turn?
The Klein Tools D333-8 locknut and reaming pliers handle 1/2 inch (13 mm) and 3/4 inch (19 mm) EMT locknuts, plus 1/2 inch (13 mm) rigid locknuts. The machined nose seats into the locknut wings so it drives without slipping off and chewing the wings. They also fit liquid tight fittings and caps. For locknuts larger than 3/4 inch EMT you need a different tool.
2) Can one tool ream conduit and set locknuts, or do I need a separate reamer?
Both jobs are in the D333-8. It reams and deburrs the inside and the outside of the conduit cut, then sets or backs off the locknut with the machined nose. On an EMT run up to 3/4 inch that replaces carrying a separate reamer and a channel-lock for the locknut. Outside deburring matters as much as inside, since a raised burr on the OD fights the connector going on.
3) Are the handles insulated for live electrical work?
No. The D333-8 has plastic-dipped yellow handles for grip and quick tool identification in a pouch, not an insulated rating. Treat them as a standard uninsulated hand tool and de-energize the work.
4) Will these Klein pliers grip flat steel fish tape without letting go?
Yes. The nose tip of the D333-8 carries knurled jaws specifically for gripping flat steel fish tape and wire during a pull, so one tool pulls tape and does the conduit prep. Jaw length is 1.625 inches and jaw thickness 0.5 inches, so there is real metal behind the grip rather than a thin tip.
5) What is the Klein part number for the conduit locknut and reaming pliers?
Order model D333-8 from Klein Tools. It is the 7.76 inch conduit locknut and reaming plier with knurled fish tape jaws, forged in the USA from US-made tool steel. One model, no handing or finish options to specify.
6) How fine is the tip on these pliers for getting into tight locknut wings?
Point diameter is .19 x .36 inches (0.48 x 0.91 cm), with a jaw width of 0.938 inches. That narrow machined point is what drops between locknut wings in a crowded box, where a flat screwdriver blade would skate off and a channel-lock would not fit.
