Product Description
The AN310-8 is a steel castellated hex nut conforming to Army-Navy standard specifications. Sized for 1/2-20 UNF drilled-shank bolts, this nut features a slotted crown design that accepts a cotter pin for positive mechanical locking. The castellated configuration prevents rotation and loosening under vibration and flight loads common in airframe assemblies.
Installation involves torquing the bolt to specification, then inserting a cotter pin through the drilled shank and nut slots to lock the fastener permanently. Standard on airframe hardware throughout general and commercial aviation.
