Prime-Line 9090646 Serrated Flange Bolts, 1/4 inch-20 X 3/4 inch, Zinc Plated Case Hardened Steel, (25-pack)

Brand:PRIME-LINE

3.6/5

Flange bolts feature a built in washer under the bolt head that helps to distribute the clamping load over a larger area. This "one-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. The serrations under the flange bite into the surface and help to resist loosening due to vibration.

Thread Type: Coarse, Thread Class: UNC-2A, Point Style: Blunt. Designed for use with a nut (not included) or a threaded hole of the same diameter and thread size. Serrations bite into surface and can help to prevent loosening. Flange eliminates need for separate washer. Hex bolt with a serrated circular flange under the head. Size: 1/4 inch-20 X 3/4 inch.

A little weak
I broke a few when tightening with a small quarter inch ratchet.

Used them for Jeep Grand Cherokee engine valve cover
I have been looking for replacement nuts for my 97’ Jeep Grand Cherokee valve cover. And on an aesthetic note, they are nice and shinny, I’m rebuilding this car so they add to the fresh look under the hood ????????

The ones I got were missing the 3 lines indicating case hardened/grade 5
The bag I got had unmarked tops, missing the 3 line marking shown in the listing photo and indicating that these were not the described case hardened (grade 5) bolts.
