GM Flanged Nuts Hex Head Pack of 5 Prevailing Torque M8 X 1.25 New OEM 11562489

More Views


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 deformed head that applies friction on the threads on the bolt being screwed into these bolts). These are for many different applications for many different GM vehicles. You will receive 5 nuts per order. (Contact us for a bulk pricing if you want to purchase a lot of these nuts)

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. The friction produced by prevailing torque locking features increase galling problems. Applying a liberal coating of antiseize prevents galling under most conditions.
