Every engineer who contacts us is asking one of two questions.
Which locking element performs best?
Standardised comparison testing to DIN 65151, DIN 25201-4 and ISO 16130. The Desktop Series answers this question on thousands of fasteners a year, in laboratories on every continent.

How do I design the best bolted joint?
A standard can compare locking elements. Designing a world-class joint takes more: understanding how your real parts, real interfaces and real friction behave under controlled transverse shear force. That is what the R-Series was built for — R&D instruments for engineers who design joints that stay tight by intention, not by margin — and who know how their joint holds its clamping force over the years.

Knowledge
We wrote much of what the industry knows about fastener self-loosening.
Since 2011, Vibrationmaster has published on Junker testing, DIN 25201, and the mechanics of why threaded fasteners loosen — in the trade press, in standards commentary, and here.
Beyond Junker: a paradigm shift in validating and optimising bolted joints
Validating and optimising your bolted joint design delivers safety and performance improvements, alongside streamlining costs. There is now a powerful new vibration test methodology using controlled shear force loading. It is significantly more advanced than traditional – and flawed – displacement amplitude-driven Junker Testing. This new approach enables you to…
Bestselling J121 Offers Top-notch Parallel Torque/Tension & Vibration Testing
Vibrationmaster is engaged in commercializing a number of product lines based on their proprietary, patented technology, enabling the generation of vibration profiles with the specific advantage of continuously and independently controlling frequency and amplitude.
Integrating Fastener and Bolted Joint Testing with Analysis for Product Design
Testing underpins the fastener supply chain, from the fastener manufacturer’s basic fastener product performance and specification tests to the end-user Design Engineer’s bolted joint test rig and product testing. But testing in isolation has little value for fastener manufacturers, distributors and downstream original equipment manufacturers (OEMs). Design Engineers are increasingly…
Variator Drives
Also from Vibrationmaster: the patented Variator Drive — the eccentric actuator drive inside our closed-loop platforms, supplied and licensed to machine builders.

We don't publish specification sheets. We have a conversation about your joint, and then we guide you — to the system that answers your question, or to a contract test programme that answers it faster.
