1/2"-13 × 3/4" Grade 8 Indented Hex Flange Screw – Zinc Yellow CR+6, Baked (Non‑Serrated)

Engineered for high‑strength structural and automotive applications, the 1/2"-13 × 3/4" coarse‑thread Grade 8 indented hex flange screw is commonly used in frame and chassis assemblies. The integrated non‑serrated flange provides wide, even load distribution while protecting mating surfaces, eliminating the need for a separate washer. Manufactured from high‑strength alloy steel, this fastener features a zinc yellow CR+6 finish for enhanced corrosion resistance. A post‑plating bake process helps reduce the risk of hydrogen embrittlement, ensuring reliable performance in demanding, high‑stress environments.
