A Horizontal clamp No. 6871 for secure hold-down in fixture and jig applications, offering a variable open holding arm and an angled foot for versatile mounting in machining setups.

• 3000 N maximum clamping force
• Variable open holding arm
• Automatic height compensation 35–40 mm
• Angled foot for flexible mounting

Accurate clamping that maintains process stability

The clamp delivers a maximum clamping force of 3,000 N, ensuring steady workpiece fixation under typical machining loads. The benefit is a measurable reduction in micro-movement during milling and drilling, which translates into repeatable tolerances and fewer rejects. The design focuses on functional reliability: the core mechanism provides consistent pressure while the compact footprint preserves access to the workpiece. This makes the clamp suitable for production jigs and small-batch fixtures where stability and throughput are priorities.

Flexible mounting and straightforward height compensation

Installation is simplified by the angled foot and the automatic height compensation of 35–40 mm, allowing the clamp to adapt to slight variations in workpiece height without manual shimming. The unit includes an M8 x 55 clamping screw and a range of dimensional references (for example A = 8.4 mm, B = 85 mm, C = 22–32 mm) that enable precise positioning in fixture plates. This flexibility reduces set-up time and supports quicker changeovers between components, improving overall machine utilisation and workflow efficiency.

Open holding arm design for accessible workpiece loading

The variable open holding arm facilitates easy loading and unloading of parts while maintaining a secure hold during machining. By combining accessibility with a robust hold-down function, the clamp reduces handling time and minimises the risk of collision with tooling. The adjustable clamping range (HW min. 1 mm to HW max. 31 mm) covers a wide span of part geometries, making the device a practical choice for mixed-production environments where adaptability matters.

Durable construction for dependable everyday use

Built for routine shop-floor conditions, the clamp is engineered for longevity and low maintenance. Key functional elements such as the automatic compensating mechanism and the solid clamping interface are designed to withstand repeated cycles without loss of performance. The clear numerical specifications and simple mechanical concept support predictable maintenance planning, which contributes to uninterrupted production and reliable throughput over time.
