Review on 🔩 KiWAV Motorcycle Round Bolt Cap Screw Cover Plug Black for 8mm Thread Allen Head Bolts: Complete Protection and Aesthetics for Your Bike's Allen Key Bolts! by Fred Vazquez

This product is available in two sizes with photographs illustrating suitability for covering the hex head bolts that hold motorcycle handlebars. The 6mm size ordered first is too small for screws that require a 6mm allen key like mine. I ride a Triumph Bonneville with Rox risers, six bolts total. The 8mm size fits all six, fits snug and actually looks better than the baseball caps supplied by Rox. If you are unsure whether you need 6mm handlebar bolt caps, get the 8mm top caps.
