About This Part

Screws

Externally threaded fasteners designed to be turned to assemble or adjust parts, including machine screws, cap screws, socket-head cap screws, set screws, self-tapping and thread-forming screws. This is the largest single class in the U.S. supply system and covers a vast range of thread sizes, drive types, head styles, and materials.

Reading the part number. NAS1189V3T6LK breaks down as NAS1189 — the National Aerospace Standard that fixes the part's design — plus the dash/suffix code V3T6LK, which selects the exact size, material, or finish variant from the tables on that standard. Two parts sharing the NAS1189 base are the same design in different variants.

Sourcing & Compliance

Origin, documentation & ordering terms

Country of Origin & Trade Eligibility

Country of origin: Türkiye (Turkey). Turkey is a NATO ally and a normal-trade-relations partner of the United States, and Turkish-origin end items are eligible for a wide range of U.S. federal and DLA procurements.

TAA note: Turkey is not a Trade Agreements Act (TAA) designated country, so these items are generally not eligible for TAA-covered solicitations. They are offerable under the Buy American Act and many non-TAA DLA buys. Buyers are responsible for confirming the origin requirements of their specific solicitation.

Full country-of-origin and source documentation is provided with every order. Fulfillment within 90 days of order. Minimum order may apply.

Documentation & Acceptance

Items are supplied as stock mil-spec / commercial hardware with source documentation and country-of-origin paperwork on every order. Parts are not supplied with an FAA Form 8130-3 airworthiness tag unless expressly stated on the quote. Buyers installing hardware on certificated aircraft are responsible for acceptance under their own maintenance program, repair station procedures, or owner/operator authority.
