Prime-Line M8-1.25 x 35 mm Class 8.8 Metric Zinc Plated Steel Flange Bolts (25-Pack)

Flange bolts feature a built-in washer under the bolt head that helps to distribute the clamping load over a larger area. This 1-piece design eliminates the need of a separate washer under the bolt head and is preferable for some applications as it can be more efficient and easier to use. A washer is still needed on the nut side unless using a flange nut.
