1/4"-20 × 1/2" Grade 8 Indented Hex Flange Screw – Zinc Yellow CR+6, Baked (Non‑Serrated)

Designed for demanding structural and automotive applications, the 1/4"-20 × 1/2" coarse‑thread Grade 8 indented hex flange screw is commonly used as a frame or chassis bolt. The integrated non‑serrated flange distributes load evenly without damaging mating surfaces, eliminating the need for a separate washer. Manufactured from high‑strength alloy steel, it features a zinc yellow CR+6 finish for enhanced corrosion resistance. A post‑plating bake process reduces the risk of hydrogen embrittlement, ensuring reliable performance in high‑stress environments.
