Belt Buckles Explained: Types and How They Work
Quick answer: A belt buckle is the fastener that holds a belt closed. There are three main mechanisms: a pin (prong in a hole), a clip (toothed clamp) and a ratchet (locks onto a track on the strap). Choose a buckle that matches your strap width exactly. Our buckles run $22 to $24 and swap onto compatible straps.
What is a belt buckle?
A belt buckle is the metal fastener at the end of a belt. It holds the strap at the length you choose, and its finish (silver, gold-tone, gunmetal, brass) sets the look of the belt.

Choosing a buckle
- Width: buckle and strap must match (1.15 in, 1.38 in or 1.55 in). A mismatched width will not seat.
- Mechanism: a ratchet buckle needs a ratchet strap; a pin and clip buckle needs a pin and clip strap.
- Finish: silver and gunmetal suit dress and business wear; gold-tone and brass are warmer. Solid brass buckles do not plate-wear.
