Riley Q. ★★★★★

I needed a long bolt for a furniture repair and these 4-1/2" machine screws fit the bill perfectly. The slotted drive head worked well with my standard screwdriver, and the zinc coating looks clean.

Mia ★★★★★

Was replacing some old hardware on a storage rack and these threaded in smooth without any binding. The zinc coating is evenly applied and gives them a clean, professional look. They'll hold up fine in my garage where humidity is a concern.

Sophia R. ★★★★★

These fit perfectly for the bracket I was mounting, and the zinc coating is a nice touch for piece of mind. The slotted head is a bit old school, but a flathead bit drives them in straight without stripping.
