3/8"-16 × 1‑1/4" Grade 8 Indented Hex Flange Screw – Zinc Yellow CR+6, Baked (Non‑Serrated)

Designed for high‑strength structural and automotive applications, the 3/8"-16 × 1‑1/4" coarse‑thread Grade 8 indented hex flange screw is commonly used in frame and chassis assemblies. The integrated non‑serrated flange distributes clamping force evenly 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 to enhance corrosion resistance. A post‑plating bake process helps reduce the risk of hydrogen embrittlement, ensuring reliable performance in high‑stress environments.
