TRIPLE X Wheel Mud Cover threaded retainer. Custom threaded bolt is made from stainless steel, has a 7/16" step at the top to perfectly fit the existing cover (dzus) hole and includes a groove for a clip to keep the bolt on the wheel cover. Aluminium bracket with fully encapsulated steel thread insert so it won't wear out or spin when tightened (like others do). 3 of these threaded bolts/brackets meet sanctioning body requirements ... and are actually lighter than the other option of 5 steel dzus! Bolt head is 1/2" so utilizes the same wrench/impact as used on the bead lock bolts. WoO and ASCS approved. Complete with multi-grip rivets and E-Clip to keep bolt on the cover. PACK OF 3
