You’ll see a few names used for overall hardware, and they often describe different pieces of the same setup.

• Overall buckles / bib overall clasps: The front hook piece that latches onto a button on the bib.
• Tack buttons / gourd buttons: The metal button posts on the bib that the clasp hooks onto.
• Tri-glide slide buckles: The adjusters on the straps that let you change the length.
• Suspender clips: An alternative clip-on style used on some overalls and pants.

Most replacement sets include the clasp, the adjustable slider, and matching buttons. Common widths listed in product titles include 1.25 in, 1.5 in, and 2 in, with finishes like bronze, silver, black, or gold.

Swapping hardware is usually a simple DIY project. These steps can help, but always follow the specific instructions included with your set.

1. Measure the strap width so you buy the correct size (e.g., 1.5 in or 2 in).
2. Remove the old hardware by unthreading the strap from the slider and unclipping the clasp from the button.
3. Install the new slider on the strap and re-thread it for length adjustment.
4. Add or replace the button on the bib if needed. Many kits include no-sew tack buttons that press or tap together.
5. Hook the clasp over the button and test for a secure hold.

Work on a flat surface and avoid forcing parts; gentle adjustments with basic tools can help if pieces feel snug.

Most bib overalls use a combination of parts that work together for an adjustable, secure fit.

• Hook-and-button clasp: A metal clasp on each strap latches onto a tack/gourd button on the bib.
• Tri-glide slide buckle: An adjuster on the strap lets you fine-tune length without sewing.
• Suspender-style clips (on some styles): Clip-on hardware that grips fabric instead of hooking onto a button.

Replacement sets often include the clasp, the slider, and matching buttons so everything fits together. You’ll find widths called out in product titles (like 1.25 in, 1.5 in, 2 in) and various finishes to match or refresh your current hardware.

It’s the metal hook piece at the front of each strap that connects your strap to the bib button. When paired with a slide buckle, it allows quick on/off and easy length adjustment.

• Function: Hooks over a metal button (often called a tack or gourd button) on the bib.
• Adjustability: Works with a tri-glide slide so you can shorten or lengthen the strap.
• Material & finish: Commonly metal in bronze, silver, black, or gold tones.
• Replaceable: Sold in sets with sliders and buttons to refresh worn hardware.

Choosing the right clasp typically comes down to matching your strap width and preferred finish.

Match the hardware size to your strap’s inside width so it slides and holds properly. These tips can help:

• Measure the strap where the hardware sits. Common widths listed include 1.25 in, 1.5 in, 2 in, and 50 mm.
• Check product titles/descriptions for the exact size; look for a width that matches your measurement.
• Consider fabric thickness if replacing buttons—longer posts can suit thicker denim.
• Buy complete sets (clasp + slider + buttons) to avoid mix-and-match issues.
• Choose a finish (bronze, silver, black, gold) that complements your garment.

If you’re between sizes, sizing up can feel loose and sizing down can be tight, so accurate measuring typically leads to a better fit.
