Reddit reviews Chicago Screws 1/4" Plain 25 Pcs Np Silver

No way you'll ever repair that.

Buying a new belt would be much easier, but you can still replace the buckle if you want. You'll have to cut that stitching around the keeper to remove it. Then you need to punch a hole on either side of it and add some Chicago Screws. You can get those at pretty much any hardware store.

I'd add a drop of blue loctite or the screws will work themselves out over time. It won't look the best, but the screws will be covered by the belt when you wear it.

Depending on the belt width, a buckle will run you about $10 on Amazon.

Maybe try getting some 1/4 chicago screws from amazon, they look like they may exactly what you need: http://www.amazon.com/Chicago-Screws-Plain-Pcs-Silver/dp/B00355AN4U/ref=sr_1_1?ie=UTF8&qid=1451505606&sr=8-1&keywords=1%2F4+inch+chicago+screws

In Addition, you could try peening some stainless stock, I do it all the time and they work well
