AN316 Series hexagonal steel cadmium plated thin non-locking check nuts are Military Specification versions of non-locking jam nuts used typically to lock in adjustments where a male threaded part screws only partway into a female threaded part (rod ends, grub screws, bulkhead fittings, etc). AN316 Series jam nuts are thinner than the AN315 specification nuts for use in tighter installations. AN316 hex check nuts can carry half the tension load of the AN315 nut.
AN316 (REV. 11)., AIR FORCE-NAVY AERONAUTICAL STANDARD: Nut, Jam, Hexagon (25 Feb 1991). Superseded by NASM316. The Part Identification Number (PIN) for AN316 and the part number for NASM316 are identical. The part numbers have not been changed.
AN315 Series hex plain nuts are manufactured from steel and cadmium plated per QQ-P-416A, Type II, Class 3. Similar to common nuts but with a rugged construction they are designed and built with aviation grade materials and to specific aviation design specifications. They can carry the same high tension load as the AN310 castle nuts and require an auxiliary locking device such as a check nut or lock washer. The following letters are used to designate specific types of airframe nuts:
"C" before dash number for corrosion resistance steel nuts
"D" before dash number for aluminum-alloy nuts
"L" after dash number for left-hand thread
"R" after dash number for right-hand thread
A plate nut, also known as a nut plate, anchor nut or anchor plate, is a stamped sheet metal nut that is usually riveted to a workpiece. They have a long tube that is internally threaded and a plate with two clearance holes for rivets. These terms are used interchangeably throughout product presentations to describe respective products.
Floating nut plates are low profile and lightweight plates used to install a captive nut behind a panel. The floating nut allows for an assembly that is not perfectly aligned. These lightweight, low-profile nut plates are designed for blind mounted applications where it is impractical to use hex nuts or where it is desirable to have an attached nut for ease of maintenance. F5000/MS21059 Series floating two-lug nut plates by HOWMET AEROSPACE (ARCONIC) are made of C1050 carbon Steel per AMS5085 or 8740 alloy steel per AMS6322. They are cadmium plated per AMS-QQ-P-416, Type II with dry film lubricant (F5000) or carbowax (F5000-CW). They are superseded by NASM21059 series.
