  1. What is the purpose of the DFARS (Defense Federal Acquisition Regulation Supplement) clause related to aerospace fasteners?

    Answer: It restricts the use of specialty metals from non-domestic sources

    DFARS specialty metals clauses restrict use of non-domestic source metals (including titanium and nickel alloys) in defense aerospace fasteners.

  2. In automotive fastener engineering, IATF 16949 replaced which earlier quality management standard?

    Answer: ISO/TS 16949

    IATF 16949:2016 superseded ISO/TS 16949 as the primary automotive quality management system standard.

  3. The Hi-Lok fastener system is classified under which aerospace specification family?

    Answer: NAS (National Aerospace Standard)

    Hi-Lok and similar two-piece fastener systems are governed by NAS specifications within the National Aerospace Standard family.

  4. Which automotive standard defines the fatigue testing requirements for wheel fasteners (wheel studs and lug nuts)?

    Answer: SAE J2265

    SAE J2265 defines the fatigue and proof load requirements for wheel fasteners in passenger car and light truck applications.

  5. Under ASME B18.2.6M, which metric property class fastener is most commonly specified for automotive structural applications requiring high strength?

    Answer: Property Class 10.9

    Property Class 10.9 is the most commonly specified high-strength metric fastener class in automotive structural assemblies.

  6. The Airbus Process Specification AIMS 03-02-003 governs what type of fastener?

    Answer: Interference-fit fasteners for wing joints

    AIMS 03-02-003 covers interference-fit fasteners installed in Airbus wing and primary structural joints to minimize fatigue crack initiation.

  7. Which SAE standard covers the performance requirements for self-tapping and thread-forming screws used in automotive body panels?

    Answer: SAE J933

    SAE J933 specifies performance requirements including drive, thread forming, and pull-out torque for thread-forming and self-tapping screws in sheet metal.
