Wheel Bead Screw With O-Ring (OTK Finger Grip Style)

Wheel bead screws with O-rings (OTK finger grip style) are specialized M5 safety screws designed to prevent kart tires from breaking their bead or rotating on the rim under heavy cornering loads. The knurled "finger grip" head allows kart racers to spin them in quickly by hand, while the rubber O-ring creates an airtight seal against the wheel barrel to prevent pressure loss.
