KETEMA DESIGNED PRODUCTS: Fasteners

From pre-fabricated buildings to space applications, no fastener offers the ease of use, strength and unprecedented performance of Senior Aerospace Ketema’s Zahodiakin fasteners. These positive-locking fasteners are the most rapidly threading fastener on the market. This makes them ideal for applications requiring quick and convenient access to panel areas without sacrificing the strength of the connection.

The Zahodiakin fasteners unique foolproof design is characterized by its ability to synchronize the fastener stud with its receptacle. Misalignments are automatically corrected and there is never a cross-threading. Just place the two parts together, push, and give a half-turn with a screwdriver to complete a positive-locking, high-strength connection. In seconds.

Initially designed to secure access doors, panels and structural components under the most critical aerospace conditions, Zahodiakin fasteners have remained constant to the industry for more than 50 years of manufacture. Today, both commercial and military fastener products are available, with the military line designed to meet or exceed Mil-F-22978A (ASG).
