How to Choose a Mounting Method for Metal Hardware

Small holes at the ends or corners of the part, stitched onto the fabric. It is the most common method for a reason. It holds as long as the thread holds, the back stays flat so nothing digs in, and it works on almost any fabric — thin or thick, soft or stiff.

The cost is labor: it has to be sewn. And very thick or dense materials — full-grain leather, heavy denim — are hard work to stitch through. But for garments and fabric bags, sew-on holes are the safest, lowest-risk choice. If the part lives on cloth, this is usually where to start.

Prongs — also called foldable legs or claws — are sharp legs on the back that push through the material and fold flat to lock the part in place. The big advantage is speed: no needle, no thread, just line it up, press and fold. It can be done by hand, with no special machine. Snap buttons work on the same principle — the back grips through prongs rather than stitching.

The trade-offs are real. The hold is moderate, so under heavy pull or constant tugging prongs can loosen. The back sits raised, which can dig in against the body, so we do not recommend prongs on next-to-skin garments. And thin fabric can tear, because the load concentrates on a few sharp points. Leg count matters here — two, four or six. More legs hold better but are more work to set; for a standard nameplate, four is usually enough.

Rivets are the most secure method there is. The part is riveted on from one side and fixed permanently — once it is set, it does not come off. They shrug off vibration, tension and corrosion, and the rivet itself often reads as part of the design, the way it does on denim and belts.

The catch: rivets need a tool — a rivet gun or press — so they cannot be hand-set, and they are permanent, so there is no swapping the part later. They also need enough material thickness to bite; too thin and the rivet will not pull tight. For leather goods, heavy canvas and outdoor gear that have to last, rivets are the dependable answer: set once, done for good.

Screw mounting uses posts on the back that pass through the material and tighten against nuts. It tends to show up on higher-end pieces — luxury bags, premium belts, metal boxes — because it looks precise and considered, especially plated in gold or gunmetal, and because it can be taken apart and put back together.

The advantages are the high-end feel, the fact that it is serviceable — unscrew it to replace or repair the hardware later — and a hold stronger than prongs. The costs: extra parts (posts and nuts) and more assembly, work on both sides of the material, and a tendency to loosen over time where there is constant vibration. Buyers building a premium line tend to choose screws and accept the few extra cents — they are paying for the feel.

Adhesive is a backing of double-sided tape — peel the film, press it on. It is as simple as mounting gets: no tools, no holes, no damage to the surface. But the limits stack up fast. It is not secure, especially in heat or humidity, where the bond lets go. It needs a flat, smooth, clean surface — rough, porous or oily and it will not hold. And it has a shelf life: the adhesive ages and eventually peels.

So we only suggest adhesive for two cases: temporary use — trade-show samples, promo pieces — or surfaces you cannot drill, like a smooth metal panel or an electronics housing. For garments and bags it is a no: it washes off in a few cycles, and the complaint that follows lands back on you.

When a buyer asks us to just pick for them, we ask three questions, and the answer usually falls out on its own.

We check the back with you, not just the front. Before recommending a method, we run those three questions against your actual product — the material and its thickness, the load it will see, how you assemble. And we will say plainly when a method will not survive the use: prongs on a body-contact garment that will dig in, adhesive on something that gets washed, a rivet on material too thin to hold it.

From there it is the details that decide whether it works on the line — leg count matched to the fabric, rivet length matched to the thickness, a back kept flat where it sits against skin. It is the same principle every time: the front is what sells the part, but the back is the first thing the customer actually touches.

To point you to the right method quickly, tell us what the hardware mounts to and how thick it is, how much load and how long a life it needs, and how you will assemble it — by hand, with a sewing line, or with a rivet press. A photo of the back of a similar part, or of the spot it goes, answers more than a description can.
