inferior rag joint?

[jks67ss396]

Guys

I bought a rag joint from a reputable vendor that a lot of guys recommend here. The rag joint has regular bolts going through the rubber, where as better rag joint have the collared bolts (see thread below)

Have you guys ever used the rag joints with the regular bolts? Any problems with the install or later on?

Wondering if i should get the collared bolts or a better rag joint

thanks guys
