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

Engineered for high‑strength structural and automotive applications, the 1/4"-20 × 3/4" coarse‑thread Grade 8 indented hex flange screw is commonly used as a frame or chassis bolt. The integrated non‑serrated flange provides broad load distribution while protecting mating surfaces, eliminating the need for a separate washer. Manufactured from hardened 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.
