Customer Reviews (4.6 / 5 · 5 reviews)

Avery Z. ★★★★★

The threads cut clean and the yellow zinc finish looks uniform across all 25, which is exactly what I want when bolting down heavy equipment. Grade L9 feels sturdy in the hand, and the partial threading made alignment a breeze with a deep socket.

Riley Z. ★★★★★

The yellow zinc finish on these hex head screws looks clean and professional, and they threaded smoothly into my equipment frame without any binding. For the price per package, getting 25 high-grade alloy steel fasteners that are partially threaded feels like solid value.

Olivia ★★★★★

These L9 bolts torqued down without any issue on my tractor's drawbar mount. The hex head gave my socket a solid grip, and the partial threading made installation a breeze.
