LEA 50-A Insertion Machine for Self-Clinching Fasteners
LEA is a specialized machine designed for installing self-clinching fasteners, such as nuts, captive screws, studs, standoffs, and spacers —into sheet metal or plastic parts.
This process is known as self-clinching fastener insertion or press-fitting.
Self-clinching fastener insertion uses controlled force to press the fastener so the sheet material plastically flows into the fastener’s undercut/knurl features, creating a strong, precise, and repeatable joint—without welding or secondary operations.
LEA machines are used in electrical engineering, mechanical manufacturing, automotive production, and sheet metal fabrication—especially where reliability, speed, and easy setup are critical.
The LEA machine is available in two basic configurations: with a single-position lower tool or with a turret holding four lower tools.
Single-position version – ideal for small to medium production batches.
LEA 50-A with turret-mounted lower tool – allows rapid switching between up to four lower tools, significantly increasing productivity when combined with intuitive software.

Intuitive Control
The machine features a touch screen with intuitive controls. Setup is quick and does not require complex training, reducing unproductive downtime.

Turret Mount
The turret mount of the lower tool facilitates work and speeds up the production process. It allows the setup of four different tools and production programs. The operator is supported by graphical and audible guidance.

Safety Head
Operator safety is now a standard requirement. The Safety Head of the LEA-50A machine reduces the risk of injury without interfering with the work process.

Performance and Efficiency
The LEA-50A features a durable construction and a reliable system. Both operation and maintenance are simple, lowering operational costs and setup time.

Why LEA‑50A?
LEA‑50A is a proven solution for pressing fasteners in production runs where simplicity, reliability, and low operating costs are key.
The machine combines key features: intuitive control, quick tool change, four-tool turret capacity, and long-term stability with minimal servicing.
Ideal for operations that don’t require automatic feeding but demand smooth, uninterrupted production.
