A Clean, Industrial Accent in Functional Form

Zinc plating lends a cool, polished sheen that pairs beautifully with natural woods and matte black fixtures. Try showcasing a few fasteners in open shelving or timber frames to celebrate their honest utility. It’s a small detail that elevates everyday builds into refined, modern craft.


Choose this 50-pack of Hillman hex bolts for reliable, corrosion-resistant fastening that keeps your projects secure and looking sharp.

Good quality, but a few issues with the hidden mounts and levelness.
Size: 35x7 2Pcs, Color: Black, Size: 35x7 2Pcs, Color: Black
These are quite nice and also sturdy. Only complaint I have is that I bought a couple of these, and on one of them, only one of them, it was difficult to get the hidden mounts to go into the holes. I think it was probably a manufacturing defect thing. Also, on that particular one, it wasnt as level as the other. Not a show stopper, but if you need a perfectly level type of mounting situation, I would be careful here.
