Ella ★★★★★

Used a dozen of these on a custom gate frame and the partially threaded shank made alignment way easier than fully threaded bolts. The 18/8 stainless finish is clean and they drove in without any binding. Solid value for a hundred pack.

Olivia ★★★★★

Packed the box with these for a trailer frame rebuild and the threads cut clean with zero galling on the stainless. The unthreaded grip section really helped keep the alignment tight on the flanges.

Violet Q. ★★★★★

The partially threaded shank gave me a solid grip length when I bolted down my trailer hitch, so nothing wobbled during the drive. The 18/8 stainless finish already looks cleaner than the zinc-coated junk I pulled off, and the hex heads seated perfectly with a standard wrench.
