Screw System

Precision Engineering: The Integrated Screw System

While screw systems are ubiquitous in mechanical engineering, their application in fine jewelry requires a master’s touch. At Renfook, we utilize advanced CNC (Computer Numerical Control) technology to integrate high-precision screw mechanisms into sterling silver and gold jewelry, adding unique functionality and security to every piece.

Why Incorporate a Screw System?

Beyond its mechanical purpose, the screw system elevates the utility and innovation of jewelry:

Enhanced Security: Provides a safer closure for high-value items compared to traditional friction backs.

Dynamic Functionality: Perfect for "Open & Close" designs, such as cremation jewelry (urn pendants) and modular interchangeable charms.

Custom Innovation: Transforms a static piece of jewelry into an interactive, functional tool.

Our Technical Edge: CNC Precision

Sterling silver is a relatively soft metal, which makes traditional threading difficult. We overcome this through CNC Machining, ensuring:

High Accuracy: Perfectly aligned threads that ensure smooth rotation without jamming.

Durability: Robust structural integrity that withstands repeated use.

Versatility: The ability to create micro-screws for delicate components.

Versatile Applications

Our expertise in screw systems spans across various jewelry categories:

Jewelry Bottles & Urns: Secure screw-cap seals for 8mm tube bottles and gemstone-encrusted vials.

Secure Earring Backs: "Baby Screw" earring nuts designed for maximum comfort and safety.

Modular Bracelet Ends: Allowing for easy customization and bead replacement.

Interchangeable Charms: Screw-cap bead charms that allow users to switch elements effortlessly.

Innovation & Patents

We are proud to hold patents for our specialized screw applications in our 18K Gold Collection.

One Set, Infinite Styles: Our patented gold findings allow a single set of jewelry to work with different pearls or gemstones, offering clients a high-value, modular wardrobe at a single set cost.
