Review on 🏍️ PBYMT 6MM M6X1.5 Motorcycle Swing Arm Spools Sliders: Compatible for Yamaha FZ01 FZ03 FZ09 FZ10 YZF R1 R3 R6 R25 R125 Aprilia RSV Tuono V4 Dorsoduro (Black) - 2pcs CNC Swingarm Stand Screw by Jeremy Romero

The screws provided are so loose in the threaded holes in the swingarm that I was afraid they would break if torqued to the required torque. I measured their diameter and they are .370. A 10mm diameter stud must be a minimum size of .378. They appear to be threaded rather than sliced. I searched all over town until I found the right screws. As you can see from my photos, the correct screw has a larger major diameter, and the hex head cap is also larger in diameter and better fits the drilled hole on the spool, resulting in a larger head shoulder holding the spool. Also, each spool consists of 2 parts, a spool part and a separate larger flange. On the back of the flange is a small diameter protrusion protruding from the swing arm side. If your swingarm's threaded holes are severely chamfered, this bushing will fit into the chamfer rather than having to fit snugly against the face of the swingarm.
