  • Good connectors?
Color: 400PCS Bullet Connectors
These are good bullet connectors. They connect to other of the same fittings. The price was ok, as was the quality. They are electrical connectors, not entirely sure what you want me to rate here.

  • Great bullet connectors.
Color: 400PCS Bullet Connectors
I bought the correct crimping tool for these and they make professional looking bullet connections. Bite the bullet (literally) and get these so you can stop using the hardware store ones that are terrible.

  • Does not fit standard USA trailer flat-four plugs
Color: 400PCS Bullet Connectors
This is the second set of these I bought - I researched and was sure these would fit my boat trailer flat-four plug. But they are too small. Make sure you look better than I did if this is your goal.

  • Needs OPEN BARREL Crimping tool.
Color: 400PCS Bullet Connectors
The connectors worked good. I struggled crimping and asked electricians what crimp tool I needed . No one had an answer. After much frustration I found out they require and OPEN BARREL crimp tool (looks like a heart shape). It’s in their pic but not very good picture. Super nice factory crimps after getting the correct tool. ... show more
