Customer Reviews (4.2 / 5 · 5 reviews)

Olivia F. ★★★★★

The threading is clean and consistent across all 100 screws, which made assembly much faster than I expected. The yellow zinc finish looks good and should resist rust in my shop environment.

Michael R. ★★★★★

The yellow zinc finish looks great on the machine frame and the fully threaded design made it easy to adjust the clamp depth. Packed 100 to a box, so I’ve got plenty left for the next job.

Ruby T. ★★★★☆

Used a dozen of these to bolt down a small workbench frame and they drove in clean without any stripped threads. The grade 5 steel feels solid for the price, though the yellow zinc is a touch more orange than I expected.
