Daniel X. ★★★★★

Picked up these 1/2-20 hex cap screws for a jig I'm building, and the 3-inch length was just right for the setup. The partially threaded shaft made installation easier than I expected.

Daniel ★★★★★

I needed some strong bolts for a trailer hitch repair, and these Grade 5 hex heads were a perfect fit. The zinc finish looks solid and the partial threading made installation much easier than expected.

Aurora ★★★★★

Finally got the cross-threaded bolts off my wood-splitter and these Grade 5 replacements threaded in smooth as butter with a socket. The yellow zinc finish looks good and should resist rust better than plain steel.
