Review on 🔧 Set of 10 POWERTEC 71068 T-Track Knobs with 1/4-20 by 1-1/2" Hex Bolts, Washers - Enhanced SEO by Joe Fulce

I liked these handles and bolts except the heads don't hang well in the T-rail so made my mount with that, not easily adjustable . The screws are standard 1/4-20 and although they match the material of the T-track, the hex tips will hook into the walls of the T-track. Also, the heads are thick enough to be hung, so stepless panty adjustment is not possible. After figuring out why they are hanging, I sanded down the corners of the hex heads. They still tended to sag, so I cut off about half the thickness of the head. Now they work better. If you plan on using them with a T-rail and need some adjustment, I would suggest just getting the handles and buying the T-rail bolts separately.
