The YOUNG ENGINEERS, Inc. continues to develop innovative fasteners and components for
honeycomb and aircraft interior structures.
We have partnered with the product design development firm
Applied Concepts Aircraft Solutions, Inc. of Stuart, Florida on the development of
two new patent pending products:
the Loret Isolator Insert™ and
the Loret Latches™.
The Loret Isolator Inserts™
The revolutionary design of the Loret Isolator Insert™ family of products allows for their use in most common honeycomb panels,
along with sheet metal and composite structures. They can be used to dampen vibration and/or motion in such diverse applications as
avionics racks, sidewall panels, chiller and entertainment units, galleys, monuments, etc. They are currently being utilized on
VIP aircraft applications, and are being evaluated and/or tested on a variety of additional platforms. Additionally, we are
developing a non-metallic version for lightweight applications.
The Loret Latches™
This new latch system concept was developed to bring aesthetic innovation back to the aerospace industry and to allow for the development of new and
aesthetically pleasing designs customized to our customer's wishes. The Loret Latches™ family consists of a unique two part design composed of a
mechanism assembly and a separate actuator assembly, the latter of which is the visual and operational part of the latch. This design allows the
use of a similar mechanism assembly with a wide selection of actuation devices, including push button, rocker button or paddle styles. The latch
can be mounted to various panel sizes, is easy to install, and includes an integrated back plate. You may choose from our wide range of existing designs,
or we can custom design a latching solution for your specific application.
To meet the demand for lighter weight fasteners, we have designed and manufacture a full range of
non metallic fasteners, as noted below. As one of only a handful of approved
polyamide-imide (Torlon®) fastener manufactures in the world,
we are preeminently qualified to assist with your non-metallic fastener needs.
TYE4001 Series Torlon® Threaded Fastener
This threaded, self-locking (per NASM25027) fastener is made from polyamide-imide (Torlon®), and offers
significant weight savings over our very popular TYE2001 (NAS1836) steel or cres fastener. A TYE4001 fastener
designed for a 0.375" (9.53 mm) panel is approximately 73% lighter than an equivalent TYE2001 steel or cres fastener.
Even with such significant weight savings, tensile loads in excess of 700 lbs (3100 N) have been achieved.
TYE4003/4004 Series Non-Metallic Fasteners
These fasteners are the non-metallic equivalents of our TYE2003/TYE2004 Series (NAS1834) through-hole and countersunk
through-hole fasteners. They are available in either polyamide-imide (Torlon®) or polyetherimide (Ultem®), and in a variety
of standard lengths and clearance hole combinations. For a ½" (12.7 mm) long fastener, weight savings of 65-80% can be
experienced over their equivalent aluminum and steel cousins.
TYE4018/4024/4334 Series Non-Metallic Floating Nut Fasteners
These floating nut fasteners combines the best of both worlds: a lightweight, corrosion-resistant
polyetherimide (Ultem®) housing with an all-metal self-locking nut element. Modeled after our extremely
popular TYE2018, TYE2024 and TYE2334 Series, these fasteners are finding quick acceptance throughout
the aircraft interior marketplace. A TYE4334 fastener used in a ½" (12.7 mm) panel is approximately
50% lighter than its TYE2334 steel or cres housing counterpart, and about 40% lighter than the aluminum
housing variant. Tensile and shear values for the TYE4334 fasteners are similar to their TYE2334 all-metal
counterparts.
TYE4036 Series Non-Metallic Fastener with Metal Threads
This variant of our non-metallic fastener line provides the security and stability of a metal, self-locking thread with a
non-corrosive Polyether-imide (Ultem®) shell. The resulting fastener is a great weight saver, approximately 60% lighter
than an equivalent TYE2001 (NAS1836) steel or cres fastener for a 0.375" (9.53 mm) panel. When the cres nut option is selected,
the TYE4036 series also eliminates many of the environmental concerns associated with cadmium plating.
TYE4068/4168 Series Torlon® Non-Metallic Fasteners
These through-threaded, dual-self-locking (per NASM25027) fasteners are made from polyamide-imide (Torlon®),
and offer a significant weight savings over our equivalent TYE2068/2168 steel or cres fasteners. For a ½" (12.7 mm)
fastener, a weight savings of approximately 73% can be experienced.
TYE4094 Series Torlon® Floor Panel Fastener
This corrosion-resistant, plug and sleeve fastener is made from a high-strength engineering polymer (polyamide-imide; Torlon®),
and is designed as a replacement for aluminum floor panel fasteners. They are particularly well suited in applications where galvanic
corrosion may be encountered, and work extremely well with graphite panels. Testing in carbon fiber faced panels yielded shear
strength values of approximately 1400 pounds (6200 N). These parts are currently being utilized in various aircraft types and are
being evaluated by additional OEM’s and end users. Considering that such fasteners are lighter than aluminum and are FAA TSO C148 approved,
they will likely find many applications.
TYE4122 Series Non-Metallic Fastener
This lightweight, bonded-in, one-piece, polyetherimide (Ultem®) fastener is a perfect solution for lightweight and
moderate-strength countersunk clearance hole attachments.
TYE4204 Series Non-Metallic Fastener with Metal Threads
This latest variant of our non-metallic fastener line provides the
security and stability of a metal, self-locking thread with a non-corrosive,
environmentally sensitive composite shell. The resulting insert is a great weight
saver, and also eliminates environmental and corrosion issues.
Additional innovative fastener designs include:
TYE2024 Series Floating Nut fastener
With continuous emphasis on weight reduction, designers are utilizing thin and lightweight honeycomb panels in greater
numbers. Therefore, we developed this floating nut fastener for use in 0.250" (6.4 mm) thick panels as a compliment to our
full line of floating nut fasteners.
TYE2043/2046/2054 Series Thin Panel fasteners
These fasteners are designed for honeycomb panels as thin as 1/8" (3.2 mm). They are available in through hole (TYE2043),
through threaded (TYE2046), and countersunk (TYE2054) versions. With increased emphasis on aircraft interior weight reduction,
designers and users are increasingly utilizing thin honeycomb panels for lightweight applications such as decorative panels,
partitions, etc. Testing conducted in a typical 1/8" (3.2 mm) panel have generated tensile and shear values in excess of
170 pounds (756 N) and 525 pounds (2335 N), respectively.
TYE2335 and TYE2336 Series Independent Floating Nut fasteners
This double-sided floater was designed for locations where two-sided, independent floating
nuts are preferred to mounting two inserts back-to-back, or where panel thickness
prohibits the latter. In the past, designers and installers were often required to
offset inserts on opposite sides of the same panel, even though they would have
preferred the same mounting location (e.g., drawer glide installation in a bank of
drawers). This resulted in additional labor, and potential reduction of panel
strength. Our new fastener eliminates all of these concerns, and is available for
nominal panel thickness of .500" and greater
TYE2344 Series Floating Nut Fastener
This floating nut fastener was designed for applications where a flush installation is required in addition to a radial float.
A cres version of this fastener is designed into the cockpit flooring on the Airbus A380.
TYE5204 Series Floor Panel Fastener
This fastener was designed to meet the high strength shear requirements set forth by aircraft OEMs. When tested in a carbon fiber and Kevlar® panel,
shear strength values of over 2500 pounds (11 kN) were generated. This one piece, primer coated, non flared fastener also eliminates some of the
problems typically encountered with flared floor panel fasteners (e.g., non flush and/or incomplete installation after flaring), and is
installed quickly and efficiently without special tools.
TYE6171/6172 Series Hot Melt Adhesive Studs
These studs, along with their internally threaded TYE6109 Series companion, are designed to hold lightweight assemblies
such as wire looms, and can be installed without potting compounds, extensive cure times or significant panel preparation.
A TYE designed adapter tip applied to a standard soldering gun is all that is needed to install these fasteners,
and they are ready to use in as little as fifteen minutes. Tensile loads of over 150 pounds (667 N) have been developed on typical panels.
