Yes absolutely. Don't use a flathead screwdriver. Go ahead and fine either a wrench or better yet a ratchet with a socket (looks like it might be 7mm) to fit over that turn bolt. Loosen it up a bit, and then fit the entire sleeve so that it sits flush on the turbo outlet. You're gonna wanna tighten those bolt really good. You're gonna wanna apply enough force and torque on it until you get almost no resistance back from the bolt. I doubt you gotta worry about 'warping' the turbo outlet with a 7mm worm clamp. I could be wrong though. Maybe
@Buldawg76 or
@Coyote Chaser can offer the amount of force you wanna strive for. But I personally think you have to worry too much about it. I've really applied some force on mine and I have yet to warp anything.
