Customer Reviews (4.6 / 5 · 5 reviews)

Edward C. ★★★★★

For mounting a heavy electrical panel, these 1/4-20 x 3-1/2" machine screws gave me plenty of thread engagement—the zinc coating seems thick and should resist rust well.

Jason ★★★★★

The truss head sits nice and flush against the metal bracket I was fastening. The zinc coating looks consistent and should hold up fine indoors.

Matthew J. ★★★★★

Finally found 3.5-inch machine screws in 1/4-20 that don't strip out—the zinc coating is smooth and the truss head sits flush on my workbench brackets.
