The YOUNG ENGINEERS, Inc. continues to develop innovative fasteners and components for honeycomb structures.

We have recently partnered with the product design development firm Applied Concepts Aircraft Solutions, Inc. of Stuart, Florida on the development of two new patented products: the Loret Isolator Insert™ and the Loret Latches™.


The Loret Isolator Inserts™
The revolutionary design of the Loret Isolator Insert™ family of products will allow for their use in most common honeycomb panels, along with sheet metal and composite structure. They can be used in applications including the installation of avionic equipment, bulkheads, cabinets, galleys, monuments, sidewall panels, etc. Please contact us to discuss your application.








The Loret Latches™
This new latch system concept was developed to bring aesthetic innovation back to the aerospace industry and to allow for the ongoing development of new and aesthetically pleasing designs customized to our customer's wishes, all at an affordable price. 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 us to use the same mechanism assembly with a wide selection of actuation devices, including push button, rocker button or paddle. The latch can be mounted to various panel sizes, is very 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 are now manufacturing several new non-metallic fasteners:

TYE4036 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.



TYE4003 Series Non-Metallic Fastener
This fastener is the non-metallic equivalent to our TYE2003 Series (NAS1834) through-hole fastener. It is available in either Polyamide-imide (Torlon®) or Polyether-imide (Ultem®) in a variety of standard lengths and clearance hole combinations. For a one-inch long fastener, weight savings of 45-75% are experienced over its equivalent aluminum and steel cousins.

TYE4004 Series Non-Metallic Fastener
This fastener is the non-metallic equivalent to our TYE2004 Series (NAS1834) countersunk through-hole fastener. It is available in either Polyamide-imide (Torlon®) or Polyether-imide (Ultem®) in a variety of standard lengths and clearance hole combinations. For a one-inch long fastener, weight savings in excess of 45-75% are experienced over its equivalent aluminum and steel cousins.

TYE4334 Series Non-Metallic Floating Nut Fastener
This floating nut fastener combines the best of both worlds: a lightweight, corrosion-resistant housing with an all-metal self-locking nut element. Modeled after our extremely popular TYE2334 Series, this fastener will likely find quick acceptance throughout the aircraft interior's marketplace. A weight savings in the neighborhood of 15% is experienced over its aluminum housing equivalent.

TYE4094 Series Torlon® Floor Panel Fastener
This corrosion-resistant, plug and sleeve fastener is made from a high-strength engineering polymer (Polyamide-imide), and is designed as a replacement for aluminum floor panel fasteners. They are particularly well suited to applications where galvanic corrosion may be encountered, and work extremely well with graphite panels. Recent testing using a carbon fiber faced panel yielded shear strength values of nearly 1400 pounds. Considering that such inserts are lighter than aluminum and are FAA TSO C148 approved, they will likely find many applications.

We have also developed and tested other innovative fasteners, principally designed for aircraft flooring:

TYE5204 Series Floor Panel Fastener
This insert was designed to meet the high-strength shear requirements being set forth by the major aircraft OEMs. When tested in a carbon fiber and Kevlar® panel, shear strength values of over 2500 pounds 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.

TYE2344 Series Floating Nut Fasteners
This floating nut fastener was designed for areas where a flush installation is required in addition to a radial float. A Stainless steel version of this insert has recently been designed into the cockpit flooring on the Airbus A380.



More innovative fasteners:

TYE2043 Series Thin-Panel fastener
This insert is used in 1/8" honeycomb panels. They are available in through-hole and through-threaded (TYE2046 Series) versions. With increased emphasis on aircraft interior weight reduction, designers and users are increasingly utilizing 1/8" honeycomb for partitions and other light-weight applications. Until now, no specific honeycomb panel fasteners had existed for 1/8" applications.

TYE2024 Series Floating Nut fasteners
With continuous emphasis on weight reduction, designers are utilizing thin honeycomb panels in greater numbers. Therefore, we developed this floating nut insert for use in .250" thick panels as a compliment to our full line of floating nut inserts.


Hot-Melt Adhesive Stud
This insert, along with its internally threaded companion TYE6109 Series, 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 standard soldering gun with an attachment tip is all that is needed to install these fasteners. They are ready to use in as little as fifteen minutes.

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
