Cotter pins are used to secure bolts, screws, nuts, and pins. Military standard MS24665 split cotter pins are made from cadmium plated steel, replacing those of AN380 series or passivated corrosion resistant steel (CRES), replacing those of AN381 series. The CRES cotter pins are more resistant to corrosion and also used where heatresisting attributes are desired, such as forward of firewall or  in locations where nonmagnetic material is required. Regardless of their shape or material, all cotter pins serve the same general purpose - safetying. MS24665 split cotter pins are superseded by respective part numbers of NASM24665 series.

MS24665 Series split cotter pins are offered as part of our own branded (AVIATIONEU NEW ERA) product lines in cadmium plated steel or passivated corrosion resistant steel and in different diameters and lengths. Sold in pieces. For more information, please refer to the supplied documentation or contact us.

National Aerospace Standard (NAS) bolts come in a large variance of lengths, thread types, head type, and materials. NAS bolts are suitable for high strength applications. They are the same as Army-Navy (AN) bolts, except they may be either raised or recessed.

NAS bolts are offered as part of our own branded (AVIATIONEU NEW ERA) product lines. They are sourced from quality producers and structured in different series. 

AVIATIONEU NEW ERA NAS428 series of machine (non structural) bolts are fully threaded, crowned hexagon head bolts made from cadmium plated steel or corrosion resistant steel (CRES). These bolts are offered with drilled or undrilled head or thread in different thread sizes, diameters and lengths in inches and sold in pieces. The number after NAS428 ( - ) denotes the thread size in 1/16th inch increments.The number after the last dash ( - ) is the overall length under the head. If this number is a single digit it is 1/8 of an inch. If it is a two digit number, the first is whole inches, the second is additional 1/8ths. For more information, please refer to the supplied documentation or contact us. 

Sourced from quality producers, NASM/MS 21042/21043 and NAS1291 series nuts are offered as part of our AVIATIONEU NEW ERA product lines.

The NAS1291 series lock-nuts are widely used throughout the aerospace industry. They are thin-walled, self-locking nuts with a reduced height and are made of corrosion resisting (stainless) steel or cadmium plated alloy steel with or without dry film lubricant for 450 deg. F use. The nuts from corrosion resisting steel are designated by the letter "C" after NAS1291. The NAS1291 series of nuts ranges in size from 02 to 10, with corresponding thread diameters of .086 to .6250 inches. Some versions of the NAS1291 lock-nut have been superseded by NASM21042/MS21042 and NASM21043/MS21043 series. 

The MS21042 series (superseded by NASM21042 series) are all-metal hexagon reduced height self-locking nuts, rated at 160,000 psi tensile strength, made of cadmium plated steel. They are shorter than the AN363 nut but develop the same tensile strength. They are also  lighter than AN365 nylon lock nuts (an average of 63% lighter for sizes -3 through -6).The NASM21042/MS21042 lock nuts are widely used throughout the aerospace industry together with those of MS21043 series (superseded by NASM21043) all-metal reduced hexagon, reduced height self-locking nuts with a ring base made of corrosion resistance steel and silver plated. Because of their reduced hex dimension, they are widely used in limited space applications where wrench access is a problem. Both are designed for use in high temperature installations (up to 450°F for MS21042 series  and up to 800°F for MS21043 series nuts). They both come without or with or  a dark grey dry film lubricant (Lubed) indicated by the letter "L" in their part number.

The NASM21043/MS21043 series are used to replace certain versions of older NAS1291 series thin-walled reduced height self-locking nuts, made of corrosion resisting (stainless) steel or cadmium plated alloy steel (see product presentation).

For more information please refer to the attached documentation (dash numbers struck through are inactive for new design).

Clevis pins are used as a quick and secure fastener in place of bolts and rivets. Clevis pins can be partially threaded or unthreaded. Unthreaded Clevis pins have a domed head at one end and a cross-hole at the other end. A Clevis pin is inserted through the holes at the pronged ends of a Clevis and is kept in place by a cotter pin. Threaded Clevis pins are partially threaded on one end with a formed head on the other.

MS20392 series Clevis pins are straight, headed pins with a drilled shank. They supersede those of AN392 to AN396 series and those of AN400, AN402, AN404, and AN406 series. MS20392 series Clevis pins are produced in different materials (steel alloy, corrosion resistant steel (CRES), titanium alloy) and surface finishes (cadmium plated, chrome plated, titanium alloy - aluminum coated) with a drilled hole for cotter pin. The following letters in the part number specify materials and finishes:

“C”  Steel alloy, 4037 4130 8630 or 8740 cadmium plated

“S”  Steel alloy, 8740 cadmium plated

“R” Corrosion resistant steel, PH13-8Mo chrome plated

“P” Corrosion resistant steel, PH13-8Mo cleaned descaled and passivated

“A” Titanium alloy Ti-6AI-4V, aluminum coated and lubricated with solid film lubricant

“T” Titanium alloy, Ti-6AI-4V, no finish

MS20392 series Clevis pins are offered as part of our own branded (AVIATIONEU NEW ERA) product lines in different materials, head, shank diameters and effective lengths. They are used with clevis forks and in secondary controls which are not subjected to continuous operation. For more information, please refer to the supplied documentation or contact us.

Blind Rivets are multi-piece rivet assemblies, capable of being installed from one side of the workpiece.Traditionally, blind rivets were used on aircraft leading edges, trailing edges, and close out areas which are limited to access to one side of the structure.  Current blind rivet usage has expanded to many additional areas of the aircraft in an effort to decrease labor expense and to address the ergonomic issues of solid riveting.

The CherryMAX® rivet by CHERRY® AEROSPACE is the most reliable, high strength structural fastener with visual inspectability in the world today.  It features the "Safe-lock" locking collar for more reliable joint integrity, and meets the requirements of PS-CMR-3000. CherryMAX® fasteners are currently available in 1/8" through 1/4" diameters in both nominal (CR3212 and CR3213 Series) and 1/64" oversize diameters (CR3242 and CR3243 Series). 

Please refer to the supplied documentation and the Product Description section for detailed information on CherryMAX® rivet and other blind rivets manufactured by CHERRY® AEROSPACE. 

A hydraulic wiper or scraper prevents contamination of the hydraulic medium that could damage wear rings, seals and other components. They are installed in sealing configurations in hydraulic cylinders to scrape dirt, foreign particles, chips or moisture from the rod of a hydraulic cylinder as it retracts into the hydraulic system.

TRELLEBORG offers a wide range of hydraulic scrapers and wipers in metal, elastomer, Turcon® Polytetrafluoroethylene (PTFE) based material or Zurcon® polyurethane. These include the Turcon® Excluder®, which is the Trelleborg proprietary design of double-acting hydraulic scraper. Specially engineered for hydraulic cylinder applications, Turcon® and Zurcon® materials demonstrate excellent low-friction properties providing exceptional resistance to wear.

TRELLEBORG Turcon® and Zurcon® Excluders are offered in Metric or Inch versions, in different sizes either as sets with matching o-rings or without o-rings. Appearing prices of Turcon® and Zurcon® Excluders relate to sets of scrapers and o-rings unless otherwise specified. Please refer to the description of individual products for additional information and the attached Part Number Guide for Aerospace applications.
