The NAS1423/NAS509 series hexagon nuts fall into the jam (aka check or thin) nut category. Jam nuts are a style of nut that features a low profile, typically half the height of standard nuts and diagonal drilled holes. Their minimal thickness allows them to fit in tight spaces where ordinary nuts might not fit. NAS1423 series jam nuts are manufactured from 4130/4340 cadmium plated steel alloy or unplated A 286 stainless steel (designated by the letter "C" in the part number). NAS509 series jam nuts NAS1423 series jam nuts are manufactured from 4130/4340 cadmium plated steel alloy or corrosion resistant steel passivated (designated by the letter "C" in the part number).

Sourced from quality producers, the NAS1423/NAS509 Series check nuts are offered as part of our own label (AVIATIONEU NEW ERA) product lines with Right or Left  Hand threads in different sizes in inches. Letters "R" and "L" in the end of the product reference number (SKU) indicate a Right or Left Hand thread respectively. Sold in pieces or packs of specified nuts per pack indicated after the letters "PK" in the product reference number (SKU).

Steel Nut Specifications:

Material - 4130 Alloy Steel Per AMS-S-6758

Finish - Cad Type II, Class 2 Per AMS-QQ-P-416

Heat Treat- 150 KSI Min Per AMS2759

Hardness - 34-38 HRC

Thread Series & Class: UNJF 3B (Unified National Fine thread series with external thread controlled root radius)

Note: UNJ, UNJC, UNJF and UNJEF thread series are almost identical to the respective UN, UNC, UNF, and UNEF threads except that the external J thread has a much larger root radius than the standard UN threads and inspection must be performed on this element. The Special UNJ threads are designated by the nomenclature UNJS. J screw threads feature a root radius which improves the tensile stress area of the fastener and helps to reduce the stress concentration factor in the thread thus making the thread stronger. Additionally, the requirement for high strength is achieved with 3A and 3B classes of fit. All pitch diameters and tolerances are based on the Unified Inch Standard.

A castellated nut, also referred to as a castle nut or slotted nut, is a nut with slots (notches) cut into one end. Although castellated nuts are frequently referred to as slotted nuts, there are slight differences. Castellated nuts are formed with a round section at the top where the slots are located. Slotted nuts do not have this rounded modification. The flat sides of slotted nuts extend fully from the top to the bottom of the nut. Both castellated and slotted nuts are designed to use a pin (usually a split pin) that fits through the slots and through a hole in the screw to which the nut is attached. This pin prevents the nut from turning and loosening. Compared with slotted nuts, castellated nuts allow the cotter pin to be confined closer to the margins of the nut itself, providing added secureness.

MS17825 Series nuts are slotted hexagon style lightweight castellated self locking nuts manufactured  from cadmium plated steel to standard castle or shear nut specifications with a nylon insert added for positive safety. They are offered as part of our own labelled (AVIATIONEU NEW ERA) product lines and can be used throughout the control system. In case the cotter pin used with castle nuts is overlooked, the nut cannot work loose. The nylon insert will act as a stop nut.

Anchor nuts (aka nutplates or anchor plates) are terms used interchangeably and relate to stamped sheet metal fasteners with an internally threaded tube and a plate with two clearance holes for rivets. They are used in blind mounted panel applications in aerospace and other industrial sectors where hex nuts cannot be used or an attached nut is required for ease of maintenance. 

Anchor nuts can be Fixed or Floating, the latter being easier to use due to their built-in nut (threaded hole) able to "float" slightly thus providing a convenient connection point for threaded rods, such as bolts, from the backside. In the case of Fixed anchor nuts, the built-in nut is static (i.e. without the capability to “float”) and the threaded rod must be positioned perfectly over the hole. Self-locking anchor nuts are those with a built-in locking mechanism preventing them from loosening over time from vibrations. They are extensively used in aerospace, automotive, and construction industries.

AN310/NASM310 and AN320/NASM320 Series castlellated nuts are manufactured from steel and cadmium plated. AN310/320 nuts have been superseded by NASM310/320 Series.  The Part Identification Numbers (PIN) for AN310/AN320 and those for NASM310/NASM320 are identical.

Castellated nuts are of similar style and shape as castle nuts but they are not as thick (deep) as the castle nuts (they consist the thin version of standard castle nuts). The thin design makes castlellated nuts weaker than the castle nuts and are used only where shear stress forces are encountered. Fabricated from steel and cadmium plated per QQ-P-416A, Type II, Class 3. AN310/NASM310 castle nuts are used with drilled-shank bolts, clevis bolts, eye bolts and studs. The slots in the nut accommodate a cotter pin for safety purposes. The thinner AN320/NASM320 series castellated shear nuts, with half the tensile rating of the AN310/NASM310 series nuts, are used with clevis bolts and threaded taper pins which are subject to shearing stress only.

Both AN310/NASM310 and AN320/NASM320 Series castlellated nuts are sourced from quality producers and offered as part of AVIATIONEU NEW ERA product lines. For additional information please consult the supplied documentation or contact us.

Aircraft General Standards (AGS) were issued by the Directorate of Technical Development of the Air Ministry from the 1920’s and persist till today through substitutions to British Standards and AGS revisions. They relate to fasteners  such as bolts, nuts, rivets, fork joints, taper pins, common to all types of aircraft. AGS fasteners are made in a range of sizes and different materials. In their identification system AGS parts are listed in sequential number, eg AGS 500, AGS 501 even though the number does not generally group common parts together nor does it follow a specific chronological order. Special parts made for specific aircraft have no marking to indicate size or material, but are marked with a part number.

Anchor nuts (aka nut plates) are designed for blind mounted applications where it is impractical to use hex nuts. Stiffnuts, in particular, feature a very high friction between the threads of the nut and the bolt so that the nut may be considered self-locking. Several types of stiffnuts have been designed for use on aircraft. AGS 2007 series relates to double lug anchor locking nuts (aka thick stiffnuts) while  those in AGS 2008 and 2009 series relate to thin and countersunk stiffnuts.

AGS 2007 series anchor nuts are offered as nyloc (*) (with nylon-insert) or all-metal style. They can be furnished in different materials (aluminum, cadmium plated steel or corrosion resistant steel (CRES). Available with BA or BSF (**) threads as NEW OLD STOCK (NOS) items in limited quantities from  stocks of our co-operating suppliers as special order non refundable and non-returnable items. Please refer to the supplied documentation or contact us.

(*) Nyloc nut (aka nylon-insert lock nut, polymer-insert lock nut, or elastic stop nut) is a kind of locknut with a nylon collar that increases friction on the screw thread.

(**) British Association (BA) Threads. small sized screw threads still used in some precision instruments, such as optics and moving-coil meters, relays as well as modelling applications. Recommended by the British Standards Institution for use instead of the smaller British Standard Whitworth (BSW) and British Standard Fine (BSF) thread screws (those below 1⁄4 inch).

British Standard Fine (BSF) Threads. Screw thread form, used as a fine-pitch alternative to British Standard Whitworth (BSW) threads. Common applications include British machine tool industry and cars. Superseded by the American UNF threads and later Metric standards.

Brass nut for mounting of aircraft instruments from the front of the panel.

Titanium fasteners are best known for their strength,  lightweight, and corrosion resistance. They feature an excellent strength to weight ratio and significant mechanical properties but perhaps their most notable attribute is their superior corrosion resistance to salt water / seawater operating conditions. Titanium fasteners are used in aerospace, automotive and motorsports but also in many other industries including chlor alkali, marine, off-shore oil & gas, desalination, medical, and pulp and paper. They come in different types (like bolts, screws and nuts), sizes, titanium grades and standards/specifications (e.g. ANSI/ASME, DIN/ISO, ASTM, ASME, MIL specifications etc.) to meet application requirements. Compared to respective fasteners made of steel and aluminum, as a rule of thumb, titanium fasteners are about half the weight of their steel counterparts while aluminum fasteners are about half the weight of titanium ones.

Sourced from quality producers, a wide range of titanium fasteners are offered as part of AVIATIONEU NEW ERA product lines (please refer to the individual product presentations). 

AVIATIONEU NEW ERA Titanium nuts are available in both inch and metric systems. Their typicals uses include aerospace, marine, motorsports and many other applications.
