Part Number
Hexagon Slotted Self-Locking Nut · MS (Military Standard) · 2 stocked variants
Reading the part number. MS17826-10 breaks down as MS17826 — the Military Standard sheet that fixes the part's design — plus the dash/suffix code 10, which selects the exact size, material, or finish variant from the tables on that standard. Two parts sharing the MS17826 base are the same design in different variants.
Because MS17826-10 is a specification-level reference, each conforming variant carries its own National Stock Number. The table below lists every variant we stock, with its decoded characteristics and published price — open the NSN record to see the full specification and order that exact item.

Country of origin: Türkiye (Turkey) — a DFARS qualifying country. Türkiye is a NATO ally with a reciprocal defense procurement agreement with the U.S. Department of Defense, making it a qualifying country under DFARS 225.003. On DoD and DLA solicitations, qualifying-country end products are evaluated without Buy American price penalties — they compete on par with domestic product — and DoD trade-agreements clauses (DFARS 252.225-7021) expressly accept qualifying-country end products.
Dollar thresholds. The Trade Agreements Act only applies to supply contracts at or above $174,000 (the WTO GPA threshold effective March 2026); below that — where the vast majority of hardware buys fall — the TAA does not apply at all. The main exclusion is civilian-agency solicitations at or above that threshold that restrict award to TAA designated-country products (Türkiye is not TAA-designated). 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.
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.
