1/4"-20 × 1‑3/4" Grade 8 Indented Hex Flange Screw – Zinc Yellow CR+6, Baked (Non‑Serrated)

Intended for heavy‑duty structural and automotive applications, the 1/4"-20 × 1‑3/4" coarse‑thread Grade 8 indented hex flange screw is commonly specified for frame and chassis use. The integrated non‑serrated flange provides even load distribution while protecting mating surfaces, eliminating the need for a separate washer. Manufactured from high‑strength alloy steel, this fastener is finished with zinc yellow CR+6 plating to enhance corrosion resistance. A post‑plating bake process reduces the risk of hydrogen embrittlement, ensuring consistent performance in high‑stress environments.
