Kukamet 521 Push-rod Clamp — galvanised design with M12x80 pressure spindle

The Kukamet 521 is a robust push-rod clamp designed for fixture and jig use in production and workshop environments, offering secure holding with a horizontal-foot mounting for easy installation.

• Galvanised finish for corrosion resistance
• Horizontal foot for secure mounting
• M12x80 pressure spindle integrated
• High clamping force: 7,500 N

Secure clamping for repeatable production

The clamp delivers a maximum clamping force of 7,500 N and a holding force of 15,000 N, providing the necessary pressure for reliable workpiece retention during machining and assembly. These figures indicate how much force the device can apply and resist respectively, which makes it suitable for medium-duty fixtures where consistent repeatability is required. The internal piston Ø 20 mm contributes to stable actuation and even force distribution, reducing micro-movements that can affect tolerances.

Durable materials minimise downtime and maintenance

Constructed with a galvanised finish, the unit resists surface corrosion in workshop atmospheres and light humid conditions, extending service intervals. The integrated M12x80 pressure spindle is replaceable and enables simple fine adjustment of clamping travel and contact pressure; this design reduces maintenance time and keeps fixtures in production longer. The combination of robust material choice and straightforward serviceability supports continuous operations without frequent part changes.

Compact mount for flexible fixture layouts

The horizontal-foot mounting allows the clamp to be mounted on flat bases or tooling plates where vertical clearance is limited, making it easier to design compact jigs. At approximately 1.425 kg, the device is light enough for modular tooling yet substantial enough to deliver stable clamping. The lever-style mechanism derived from classic lever clamp design ensures quick actuation and clear open/closed states, helping operators to work efficiently and with fewer handling steps.

Practical advantages for workshop integration

The clamp's geometry and connection options make it compatible with common fixture concepts: bolting via the horizontal foot and fine-tuning with the M12 spindle mean it can be integrated into existing tooling without bespoke adaptors. The galvanised surface and mechanical simplicity lower lifetime operating costs through reduced corrosion and fewer wear-sensitive parts. When incorporated into a standardised tooling set, the component supports faster set-up times and improved process reliability.
