GROVE manufactures axles and hardware for use in GROVE wheels as well as those of other manufacturers.

GROVE 500x5 wheel axles (P/N. 5013 standard and P/N. 5018 with wheel pant stub) are produced from solid 2024-T3 aluminum with anodized finish. They have a 1-15/16" Bolt Circle hole pattern and 1/4" diameter holes.

500x5 1-1/4" diameter standard axle (P/N. 5013) is the most popular axle for 500x5 wheels. It is designed to fit Grove 50-1, 51-1, 56-1, 57-1, 57-5 and Cleveland 500x5 wheels. Axle Weight: 0.92 lbs. Static Load Rating 1,250 lbs.

500x5 1-1/4" diameter axle (P/N. 5018) has built-in wheel pant stub with 1/4-28 thread. It is designed for use with Grove 50-1, 51-1, 56-1, 57-1, 57-5 and Cleveland 500x5 wheels. Axle Weight: 0.95 lbs. Static Load Rating 1,250 lbs.

Both axles require two spacers per axle (P/N. 5710) sold separately.  I.D: 1-1/4", O.D. 1-3/4", Thickness: 1/4". They can be used with 500x5 axles.

Standard axle nuts and axle bolt kits sold separately are also offered as part of GROVE product portfolio. Castle type nuts are manufactured to MIL Specification MS21025 using 4140 steel. Mild steel nuts are not acceptable for use on certificated aircraft. 1-1/4" dia. nuts for 500 x 5 axles, 1-1/2" dia. nuts for 600 x 6 axles.

Aircraft washers used in airframe construction or repair works are either plain, lock, or special type washers. 

AN960/AN960L series are aeronautical (Army-Navy) standard flat washers superseded by the respective washers in NAS1149/NAS1149L series. They come in regular thickness (NAS1149/AN960) or light thickness (NAS1149L/AN960L) indicated by the letter "L" in the dash number of the product reference number (SKU). They are made from different materials such as carbon steel, corrosion resistant steel (CRES) and aluminum alloys. These washers are used under hex nuts to provide a smooth bearing surface, as shims to obtain the correct grip length for a bolt and nut assembly, and to adjust the position of AN310 and AN320 castle nuts with respect to drilled cotter pin holes in bolts and clevis pins. 

NAS1149/AN960 and NAS1149L/AN960L series washers are offered as part of our own labeled (AVIATIONEU NEW ERA) product lines. They can be furnished in different materials (such as carbon steel, CRES, anodized aluminum or aluminum alloy), different finishes and different inside, outside diameters and thicknesses in inches.  Letters in the part number of NAS1149/AN960 washers are used for material and finish specification. Please refer to the supplied documentation for information on available sizes, materials, finishes and cross reference between  AN960  and NAS1149 series washers.

Sold in packs with a specified number of washers per pack indicated after the letters "PK" in the product reference number (SKU).

The NORD-LOCK GROUP is a global leader in engineering and bolting technologies manufacturing  Nord-Lock® wedge-locking washers, Superbolt™ mechanical tensioners, Boltight™ hydraulic tensioners and Expander® System pivot pins.

NORD-LOCK® created the original wedge-locking technology utilising tension instead of friction to secure bolted joints, even when exposed to severe vibration and dynamic loads.

NORD-LOCK® wedge-locking washers offer increased operational reliability and lower maintenance costs over the operational life cycle, while significantly reducing the risks of production stops, accidents and warranty claims. Due to the wedge created underneath the bolt head and nut, unintentional loosening of fasteners is prevented. Additional features and benefits of using NORD-LOCK® wedge-locking washers include:

- Offered in steel and stainless steel material 254 SMO® providing excellent corrosion resistance for use in any general saltwater application

- Available in different bolt sizes in Metric (M3 to M42) and Inch (#5 - 1 1/2”) systems

- Available in standard and SP outer diameters. SP Washers exhibiting the same wedge-locking design as original washers, but with an enlarged outer diameter. The SP washers are designed to be used together with flanged bolts and nuts (ISO 4161,4162) on oversized and slotted holes, or on sensitive surfaces and soft materials.

- Quick and easy to install and remove with hand tools

- Locking function not affected by lubrication

- High corrosion resistance. The washers have been tested with at least 1,000 hours in the Neutral Salt Spray Test (*), ensuring optimum performance over time, even in the most extreme environments.

- Reliable locking, even for joints with short clamp length

- Reusable (depending on usage environment)

- Testing & Certification. Rigorously tested (**) and approved by independent institutes as well as certification authorities.

Commonly sold in packs of specified number of washer pairs per pack. For additional information please refer to the supplied documentation or contact us.

(*) The Neutral Salt Spray Test (NSST according to ISO 9227) is one of the most established methods to verify corrosion resistance.

(**) Junker test, the most rigorous method for testing bolted joints. During the test, the joint is exposed to transverse movements underneath the bolt head and nut, while clamping force is continuously measured. Nord-Lock washers consistently outperform the competition in this challenging environment.

AVIATIONEU NEW ERA Brass plain washers are made of copper, nickel alloy with a natural color finish in accordance with DIN 433 standard. Sourced from certified manufacturers these washers are offered in competitive prices and they are available in different sizes on the basis of their Clearance (Hole) Diameter/Outer Diameter/Thickness in mm.

Boeing & Airbus, the two leading airframe builders, have developed specifications for fasteners, hardware and other parts manufactured by different companies. Compliance with  Boeing (aka BAC) and Airbus (aka ASNA) Standards is a  prerequisite for installation or use of these parts on their respective aircraft. In many cases, Boeing & Airbus fasteners and other parts have the same fit, form, and function and they are considered as alternatives or substitutes to the respective parts designed and/or manufactured by industry leaders such as HI-SHEAR  or HOWMET in the case of fastening products.They also conform to widely accepted Military & Aerospace Standards such as AN, MS, NAS and others. However, caution is required as, depending on their series & conforming standard, fasteners are offered in Imperial (in.), Metric (mm) systems, or  both, with resulting variations in their dimensions and units of measurement of their properties.

As a result of the extensive portfolio of fastening products (including screws and bolts, nuts, washers, pins, rivets, clamps, and many others) from different leading suppliers, and those falling under Boeing, Airbus, Military and Aerospace Standards, these are listed separately in our Web Platform for Supplies.  It must be noted that, depending on the intended application, usually more than one options are available to prospective buyers and selection is finally made, apart from specifications, on the basis of price or lead time required for non-stock parts. Whenever possible,correlation tables and other information and documentation is provided to facilitate the users' awareness on interchangeability of offered fasteners and the selection of the right parts for their intended application.
