Metal Double Cap Rivets: Premium Quality with a Closed Head on Both Sides
When perfect aesthetics are essential in the production of binders, menus, sample folders, or exclusive packaging, metal double cap rivets are the premier choice. While classic machine rivets are flanged on the back and remain open, double cap rivets feature a two-part system: the upper and lower parts lock together into an inseparable unit that features an identical, smooth, closed rivet head on both sides. This not only looks much higher quality but also reliably prevents sharp edges from damaging the contents or interfering when turning pages.
Precise Dimensions for Standard and Lever Arch Mechanisms
Our range of metal double cap rivets covers all common requirements of the modern printing and packaging industry:
- Tailored Head Diameters: Choose between 6 mm (for delicate mechanisms and folders) and 9 mm (for maximum holding power and larger drill holes).
- Extra-Long Configurations: For voluminous heavy-duty lever mechanisms or particularly thick binder walls, we stock special lengths that effortlessly and stably connect thick greyboards and metal plates.
- Easy Processing: The rivets can be processed manually with matching hand tools or semi-automated in corresponding rivet presses.
Extensive Color Range and Elegant Finishes
Packaging design is branding. To ensure the rivet perfectly matches your cover material or mechanism, we offer an extraordinary variety of finishes from stock:
- Classic & Modern: Silver nickel-plated or with elegantly black lacquered heads.
- Exclusive & Noble: Deep black nickel, shiny brass-plated, or nostalgic antique brass.
- Individual: High-quality copper finish for a striking, trendy look.
- Custom Made: Do you need a very specific shank length or an exact custom color? As your B2B partner, we produce tailor-made solutions exactly according to your specifications.
The Difference: Machine Rivets vs. Double Cap Rivets
For production in the high-end sector, choosing the right rivet type is crucial. While the classic machine rivet is designed for maximum processing speed for large industrial volumes (with the reverse side rolling open), the double cap rivet represents the premium segment. It is used wherever the end customer has a direct view of the inside of the binder or folder and a clean, safe, and representative result is expected.
Frequently Asked Questions (FAQ)
What is the advantage of double cap rivets over normal machine rivets?
The main difference lies in the construction: Normal machine rivets are one-piece and roll open on the back. Double cap rivets consist of two parts (cap and shank) that interlock. This gives you an optically identical, smooth, and closed head on both the front and back – ideal for high-quality products.
Which head shape is suitable for heavy lever arch mechanisms?
For heavy lever mechanisms, we usually recommend the larger head diameter of 9 mm in combination with our extra-long shank versions. The larger head distributes the pulling pressure optimally over the folder cardboard and ensures a permanent hold.
Are the double cap rivets compatible with all common mechanisms?
Yes. Our dimensions with 6 mm and 9 mm head diameters are precisely matched to the standardized perforations of lever arch mechanisms, ring binder mechanisms, and clip mechanisms used in the packaging and office supply industries.
