Customer Reviews (4.6 / 5 · 5 reviews)

Ryan Z. ★★★★★

Installing these on a piece of machinery and the threads engaged smoothly right from the start—no binding or cross-threading. The hex heads hold a socket well, making assembly quick. For the price per thousand, you get solid, consistent quality for general industrial use.

Leo ★★★★★

I needed a bulk batch for assembling workbenches, and these fully threaded M8s grab beautifully with a socket wrench, plus the class 8.8 steel feels plenty tough for the job.

Sofia J. ★★★★★

I needed a solid batch for a frame jig, and these M8-1 x 20mm bolts are exactly what I expected. The hex heads fit my socket perfectly, and the class 8.8 rating gives me confidence in the assembly.
