Review on Efficient and Versatile - POWERTEC 71164 Cam Clamp 20 for Reliable Holding Power by Mike Sutherland

I gave it a 3 because 1/4-20 doesn't mean a t-bolt head will fit on a 1/4 mini t-track twenty . I ended up replacing the screws with 1/4-20 screws from another product sold by powertec. The product is good and the color of these clips are consistent with another famous blue company. Note: Not all Powertec products have the same blue color.
