Availability:
In Stock 4,537 pcs
A metal side-release buckle made from zinc alloy with a matte black finish is suitable for the production of collars, straps, belts, backpacks, and other leather goods. Compared to plastic versions, it gives the finished product a more distinctive, more solid look. It pairs well with other hardware in the same finish, allowing you to create a visually consistent product.
The buckle features a slightly curved shape, making it a good fit for products where not only function but also comfortable fit on the finished product is important. It is available in 8 sizes, making it easy to choose the right option for your specific application.
Even hardware needs basic care. Watch the video where we show how to maintain it so it keeps working for as long as possible.
We do not recommend washing products with this hardware in a washing machine or drying them in a tumble dryer. If the product gets wet, we recommend drying it thoroughly. Prolonged exposure to moisture is not suitable for the internal fastening mechanism. At low temperatures, zinc alloy may be more sensitive to impact, so we do not recommend exposing frozen hardware to shocks or rough handling.
Due to its smaller width, this buckle cannot be used in combination with our waterproof straps in sizes 15 and 40 mm.

Workshop opinion
Pavla Nováková
A specification can tell you plenty. The workbench tells you the rest, so that is where I test it.
I see metal side-release buckles primarily as a design upgrade. Compared to plastic, they give the finished product a more premium feel and visual consistency – especially when matched with a D-ring and other hardware in the same finish. This visual coherence is exactly why I reach for them.
From a production perspective, it’s important to distinguish between the two available versions. The Plus variant, thanks to its wider openings, easily accommodates thicker or layered materials, while with the basic version it’s necessary to keep an eye on material thickness and make sure in advance that the selected strap will pass through smoothly.
Since this is zinc alloy with a surface finish, the hardware does require a bit of care. I wouldn’t put these buckles in a washing machine or tumble dryer, where both the finish and the internal mechanism can suffer. It’s also fair to expect that metal-on-metal contact will occasionally produce a slight clinking sound, which may not suit everyone.
I choose the metal version whenever an elegant look and well-matched details are the priority. Plastic, on the other hand, works better where lightweight construction, practicality, and quiet operation come first.
