Customer Reviews (4.6 / 5 · 5 reviews)

Miles D. ★★★★★

I needed these for a heavy machinery repair and the partially threaded design made alignment a breeze. The hex head grabbed securely with my socket wrench, and the yellow zinc finish looks tough.

Andrew X. ★★★★★

These hex cap screws have a nice, solid feel to them—the yellow zinc finish looks clean and durable. I used them to secure a heavy jig on my mill table, and the Grade L9 alloy steel handled the torque without any issues. They're exactly what I needed for industrial-grade fastening.

Sofia F. ★★★★★

The yellow zinc coating on these has a really nice, even finish. They seated perfectly in my press jig with no binding at all. For heavy-duty industrial use, these L9 bolts feel like they’ll hold forever.
