Industrial polish with everyday reliability

A crisp hex head in a cool zinc tone brings an understated, utilitarian elegance to built-ins and workshop fixtures. I love the washer-faced head—such a thoughtful detail that sits flush and clean. Pair these with matte-black brackets or raw oak shelving to strike a refined, hardworking contrast. It’s the quiet hardware hero that makes a space feel intentionally crafted.

I bought these for my 2010 Toyota Tacoma and they fit perfectly! They are better than the ones that came on the truck. For the price, they are worth it all day long. They pop on in seconds and work very well. No noise. Very durable. Easy to install.

2022 Toyota RAV4 - Happy Customer
Size: 26"+16"+12A(Front+Rear Wiper Set), Style: Fit For TOYOTA RAV4 2024-2019
This is perfect for our 2022 Toyota RAV4. Amazing quality, especially for the price paid. I've used more expensive name brands before, and these punch way above their weight class. Quick install and works flawlessly, wipers didn't require any adjustments out of the box, no noise or lines.
