Gardner BenderWB1 Connector Bit Set, ¼ in. Electrical Driver, Fits: Standard and Winged Wire Nuts, 3 Pk, Black

The large one worked fine on a winged wire nut. I tightened 1 connection, knocked the drill over, and it snapped the driver off right at the end of the hex, making it totally useless. 1 wire nut. One! The other drivers do not work on winged wire nuts.Sorry, but these are all plastic construction and might last longer than 1 connection, but there are better tools available. Very disappointing if you have a house full of boxes to make up and the tool breaks on the first one.Update: I came up with a great use for these items. Take a very small drill bit and make a hole through the stem. Get some red and green paint and paint a Christmas design on them. Put a wire hook through the hole and use them as tiny Christmas tree decorations.

I used this item once with large wirenuts appropriate for the largest size and it broke as soon as it got tight. They are built very cheaply.

When I received this order I was let down like a flat tire. I was expecting metallic wire nut bits that fit my impact ¼" driver chuck. I was not expecting a very cheaply made plastic POS that doesn't fit and falls out of my chuck. I wouldn't recommend it

I used to consider Gardner Bender of good quality but this product certainly is not. The drive shanks are plastic and my first attempt at using it on a red wire nut with four number 12 AWG and it snapped within the first second.

they are made out of plastic. i think they were a little on the big to make up for being plastic. they work fine if you have the room inside the box

I find myself using these almost daily. Once you twist up all the wires, then trim the ends off this tool allows you to rapidly install a wire nut. I really enjoy the simplicity and effectiveness.

I just hold the wires together and let the nut runner put on the twist on type electrical nut. I even backed a few off afterwords and it correctly twisted the wires to make a great contact. You do not need to pre twist the wires with this in your driver.

First off, I would like to point out that they are plastic. These are not made for high torque applications and can break fairly easily. With that being said, I paid under 6 dollars for the 3 bits, so I feel they deserve 4 stars.

Pretty much a let down in the sense they do not work on any other brand.GB is only available here in limited supply, I generally use another brand, making these useless if you are not buying GB marrettes (wire nuts).Added Info: I have found this tool will also work with some other branded mid sized wing tipped wire nuts.Not standard wire nuts, but some winged wire nuts.

Does not fit any of the standard merrets that we use and is cheap plastic.

the quality has surpassed all my expectations is incredibly better does not happen

Fully plastic!... but for the price and 3 sizes to choose from, they’ll work.

Super flimsy build, with thin plastic. Oversized compared to how they could have been molded. I immediately bought a rackatiers Nut Blaster.
