This is a pack of five (5) hex flange head nuts for GM vehicles. These nuts have a flanged bottom that serves as a washer. This is a prevailing torque style nut (which has a nylon insert). These are for many different applications for many different GM vehicles. This is commonly used as the locking nut on the outer tie rod endlinks. You will receive 5 nuts per order.

Prevailing torque fasteners use a thread interference type lock where there is resistance to removal even when the fastener isn’t fully seated. Automakers often use these type of lock nuts on suspension parts to provide extra security for critical parts that may loosen due to long-term wear or other factors. Nylon insert nuts are the most common style of these fasteners.
