Customer Reviews (5.0 / 5 · 5 reviews)

Ella B. ★★★★★

For a 1:1 replacement on my bandsaw’s arbor flange, these partially threaded bolts bottomed out perfectly against the shoulder. The 10.9 steel feels noticeably denser than standard hardware store stuff, and the hex drive grabbed cleanly without rounding.

Benjamin V. ★★★★★

Used these to secure a motor mount on my lathe, and the Class 10.9 steel held up perfectly under heavy vibration. The partial threading made alignment easy with the deep flange.

Robert O. ★★★★★

I needed these for a heavy equipment repair and the partial threading let me get a solid bite without bottoming out. The 10.9 rating means they’re tougher than standard bolts.
