Discover the robust 12‑Piece Zinc‑Plated Flat‑Head Carriage Bolt Kit, engineered for reliable fastening on both wooden and steel surfaces. Each bolt measures 1/4‑inch diameter, 20 threads per inch, and extends 1‑3/4 inches, while the accompanying nuts share a matching zinc coating for corrosion resistance. The low‑profile flat head sits flush, delivering a clean finish on garage doors, panels, and frames.
Why choose this hardware set? The anti‑spin design secures the bolt during tightening, eliminating the need to access the opposite side of a door. This saves time and effort, especially on overhead or hard‑to‑reach installations. The zinc plating wards off rust, extending the life of your garage door hardware.
