This 18 cm / 7.1 in #4.5 metal pants and skirt zipper is made for garments that need a fixed-bottom closure with a clear metal-tooth appearance. It is suitable for jeans, denim skirts, tailored trousers, shorts, workwear, and many medium-weight apparel applications.
The navy zipper tape works naturally with dark denim, navy fabrics, charcoal twill, dark gray workwear, and blue-toned trouser materials. Nickel-plated teeth give the zipper a silver metal finish that can be coordinated with jeans buttons, rivets, hooks, belt hardware, and other visible garment components.
A Good Choice for Denim and Structured Apparel
Metal zipper teeth create a stronger visual effect than nylon coil teeth. This makes the zipper useful for jeans and garments where the fly detail should look durable, classic, and intentionally finished.
The #4.5 zipper size is suitable for many pants, skirt, and short constructions. It can be used for everyday apparel without the bulk of an oversized jacket zipper. For thick multilayer denim, reinforced workwear, or heavy canvas projects, test the zipper with the actual fabric stack before starting regular production.
Closed-End Zipper Construction
This zipper has a closed-end structure. Its lower end stays permanently connected, making it suitable for pants flies, skirt openings, shorts, pockets, and fixed garment closures.
It is not intended for coat or jacket fronts that need to separate completely at the lower end. For that type of construction, an open-end separating zipper is the correct choice.
Why the Right Length Matters
18 cm / 7.1 in is a frequently used length for pants and skirt patterns, but garment measurements can vary depending on the rise, fly shape, waistband construction, and seam allowance. Measure the zipper line on the actual pattern before ordering.
A zipper that is too long can create unwanted bulk or distortion near the waistband. A zipper that is too short may reduce opening comfort. Choosing the correct length makes both sewing and everyday garment use easier.
Slider and Sewing Guidance
The zipper uses a Cyprus-style semi-automatic slider. Keep the sewing line clear of the metal teeth so the slider can move smoothly and the zipper remains comfortable to use.
Do not sew directly through the metal teeth. If fabric gets caught, release the fabric before moving the slider. For production work, complete a sample on the actual fabric to check fly shape, seam placement, slider movement, and finished appearance.
Choosing Metal Teeth or Nylon Teeth
Choose metal teeth when the zipper is part of the visible garment design or when you want a traditional denim-style metal detail. Choose a nylon coil zipper when the garment needs a lighter, more flexible, or less visible closure.
This distinction is especially helpful when choosing between denim trousers and softer lightweight apparel. A metal zipper can strengthen the visual character of jeans, while a nylon zipper may feel more natural in light skirts, soft trousers, or thin fashion fabrics.
Complementary Items for Pants and Skirts
For tailored trousers and skirts, pair the zipper with a suitable waistband hook or hook-and-bar closure. For denim designs, combine it with a matching jeans button and coordinated rivets to create a more complete hardware story across the garment.
