Customer Reviews (4.4 / 5 · 5 reviews)

Timothy M. ★★★★★

The hex heads on these M16 bolts grabbed my wrench perfectly without any slipping, and the zinc coating looks clean and even across all 50 pieces. They threaded smoothly into pre-tapped holes on a steel frame I was assembling.

Penelope V. ★★★★★

Used these to bolt down a heavy press in our workshop—the hex head made it easy to get a solid grip with a socket wrench. The zinc plating seems durable and should hold up against rust in a humid garage. Perfect for the job, no stripped threads or issues.

John ★★★★☆

Got these for a machinery rebuild and the zinc coating is holding up well so far against light shop grime. The fully threaded length made positioning them in tight spots easier than expected. Only wish the pack came with a few extras, but the 50 count covered my job.
