Kolver + ZeroKey: The Future of Precision Fastening

Kolver builds high-quality industrial fastening systems in Italy, with a focus on usability, openness, and long-term customer value.

With ZeroKey’s Quantum RTLS^®, Kolver is extending its offering beyond tools by adding real-time workflow validation, full traceability, and floor-level visibility across both its customer solutions and its own manufacturing operations.

The result: smarter fastening processes where every action is verified, every step is traceable, and every process is monitored in real time.

What this Enables

Pick Validation

Ensures operators pick the right component at the right time, every time.

Guided Assembly

Step-by-step, operator-friendly workflow instructions for repeatable, standardized builds.

Fastener Validation

Every fastening event is verified in real-time with torque, angle, and precise position data.

Cart Tracking

Track work-in-progress carts across the floor with full movement history.

The Kolver Story

Since 1989, Kolver has manufactured precision electric fastening tools in Italy, with an emphasis on bringing quieter, more ergonomic, and energy-efficient alternatives to legacy systems to market.

Today, Kolver is known for combining product quality with practical usability, delivering easy-to-deploy tools for demanding industrial applications without unnecessary complexity or added feature gates.

As a Certified B Corp, Kolver also prioritizes employee wellbeing, community impact, and environmental responsibility alongside manufacturing excellence.

“Everything we think about goes back to delivering the best quality product we can at the most reasonable price we can.”

Why Kolver Partnered with ZeroKey

With a shared focus on product quality and solving customer problems without adding friction, Kolver partnered with ZeroKey to bring real-time spatial intelligence and validation to its operations.

For Kolver, ZeroKey’s key advantage is flexibility: our millimeter-accurate positioning system, Quantum RTLS, adds workflow intelligence and unmatched traceability without forcing changes to processes that already work.

Together, Kolver brings trusted fastening tools and an open architecture mindset, while ZeroKey adds real-time 3D positioning, workflow logic, and digital validation via Torque Open Protocol.

How ZeroKey Fits

Quantum RTLS adds a digital layer to Kolver’s fastening systems by connecting operator actions, tool actions, and physical location in real time. This enables Kolver to:

Verify the correct component is picked

Enforce and confirm that each assembly step happened in sequence

Validate every fastening event by position, torque, and angle

Track tools, carts, and assets across the facility

Generate complete traceability for audits, quality checks, and process improvements

In short, Quantum RTLS has allowed Kolver to shift to fully validated, data-driven assembly processes without disrupting the workflows its customers already rely on.

ACTION

Pick Validation

Verifies the correct part is picked for the current step
Distinguishes between similar-looking components in real time
Uses immediate visual feedback for wrong vs. correct picks
Prevents errors from moving downstream into final test

From Setup to Production-Ready Workflows

Kolver uses ZeroKey in its own facility and delivers the combined solution directly to customers

This setup video shows how quickly that can happen in practice: connect a Kolver tool, configure the workflow, and build a live fastening station in under an hour.

Kolver provides the fastening layer, while ZeroKey adds positioning, workflow logic, and traceability through Torque Open Protocol. This gives manufacturers a fast, flexible way to digitize manual assembly and deploy production-ready, connected workstations without heavy integration or downtime.

From Setup to Production-Ready Workflows

Case Study: Aerospace Manufacturer

A leading aerospace manufacturer used Kolver + ZeroKey to digitize fastening and workflow validation in a quality-critical environment.

MODULAR

Launched 3 live stations in initial rollout

RAPID

Went from order to deployment in ~2 weeks

TRACEABLE

Enabled 100% traceability of process steps

INTEGRATED

Deployed directly to the factory floor

In this deployment, the customer needed both advanced screwdriving functionality and a positioning-aware workflow system to support a demanding production process. To fill this gap, Kolver and ZeroKey delivered a solution that validated each step, supported quality assurance, and created full audit readiness at the station level. The result was a live production deployment built around traceability, process control, and confidence in execution.

“We really try to keep a balance between making the best products possible and bringing benefit to the environment, to the larger community.”

Built for the Long Term

What makes this story compelling is that Kolver’s vision goes beyond tool performance alone.

The company is focused on building products that last, creating a workplace where people can do their best work, and operating in a way that brings long-term value to customers, employees, and the broader community. That commitment to responsibility is part of what makes the fit with ZeroKey so strong.

Both companies are focused on helping manufacturers improve without unnecessary disruption: better tools, better workflows, better visibility, and better outcomes.
