• modelTYE4122

This lightweight, bonded-in, one-piece, polyetherimide (Ultem®) fastener is a perfect solution for lightweight and moderate-strength countersunk clearance hole attachments.

• ModelTYE4068/4168

These through-threaded, dual-self-locking (per NASM25027) fasteners are made from polyamide-imide (Torlon®), and offer a significant weight savings over our equivalent TYE20682168 steel or cres fasteners. For a ½" (12.7 mm) fastener, a weight savings of approximately 73% can be experienced.

• modelTYE2024

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.

• ModelTYE4001

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.

• ModelTYE4003/4004

These fasteners are the non-metallic equivalents of our TYE2003TYE2004 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.

• modelTYE4094

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.
