Made by reaction inovations. I bought some of these in 1/4 oz the other day..anyway, I tried using them yesterday, and found the spring to secure a bait, was really hard to get a worm or any other bait on the small screw.

I tried pulling the spring out a tad, as it was nearly impossible to get anything on without pulling it out some. I have other jigheads with them, and won't be buying the R.I. jig heads anymore.

Anyone else use these..?

Junk! All the screws broke off of mine.Get the Picasso shakedown instead,the screw is titanium. I also recently started using the owner twistlock.Its a great head with a centering pin on the spring.

I have both of those you mentioned, and they work just fine. I find that you really have to watch what you buy with regards to reaction innovation's products.. :
