Customer Reviews (4.8 / 5 · 5 reviews)

Evelyn ★★★★★

The black oxide finish on these 45mm screws looks really clean and professional, and they threaded smoothly into my aluminum jig without any galling. The hex socket drive held the bit firmly even when torquing them down to spec.

Natalie B. ★★★★★

I needed a full batch of M5-0.8 x 45mm screws for jig repairs, and these are all perfectly threaded with no burs. The Class 10.9 alloy steel feels rock-solid under torque. Only wish I'd bought the 400-pack sooner.

Violet ★★★★★

The hex socket drive really grips the driver bit tightly — no slipping even at high torque. These screws threaded smoothly into my aluminum jig without any binding. Exactly what I needed for a solid assembly.
