Customer Reviews (4.8 / 5 · 5 reviews)

Jason ★★★★★

The yellow zinc finish on these L9 screws is tough and consistent across all 20 pieces, and the fully threaded shaft made aligning the guard frame a breeze. No stripped heads or weak threads—they cinched down solid with a torque wrench.

Ruby Y. ★★★★★

Used these to bolt down a heavy press at the shop, and the fully threaded grip made installation a breeze. The yellow zinc finish still looks factory-fresh after a few weeks in a damp environment.

Ryan ★★★★★

The hex head gave my wrench a nice solid grip, and these Grade L9 bolts held torque perfectly on a heavy machinery repair. The yellow zinc looks exactly like industrial fasteners should.
