Stage 8 Locking Fasteners Celebrating Over 20 Years
Of Fail-Safe Joint Intergrity For Critical Applications

The patented Stage 8 Locking Spindle Nut is comprised of 5 parts; a thrust washer, a specialized notched washer, the spindle nut (which can be set to an individual pre-load value), a locking retainer and a heavy spring steel snap ring. The Locking Spindle Nut assembly is easily installed without any specialized tools and spindle nut itself can be locked within ½ degree of any position so you will never have to over or under torque and will maintain the required bearing preload value. This extremely tough innovation withstands severe reverse torque, a real plus when you’re 25 miles away from civilization.
