Daniel O. ★★★★★

The slotted heads on these machine screws grip my standard flathead driver perfectly, so no cam-out frustration during assembly. Just finished a small deck repair project and the zinc coating gives me confidence against light moisture.

Abigail P. ★★★★★

Put these in to replace some worn out deck hardware and the zinc coating looks good enough to blend right in. The 1‑7/8" length gripped through the wood without poking out the other side, which saved me a trip back to the hardware store.

Elizabeth C. ★★★★★

The slotted heads bit my driver perfectly without any cam-out, which is rare for machine screws this size. Packed 200 to a box and every single one threaded clean into my tapped holes, so I've got plenty left over for the next project.
