AMF Horizontal Clamp No. 6871, Size 20 — Angle Base, Variable Open Holding Arm

The AMF Horizontal Clamp No. 6871, Size 20, Angle Base is a compact horizontal clamp for secure workholding in machining and assembly applications, featuring a variable open holding arm and an angled base for flexible mounting.

• Variable open holding arm for versatile use
• Angle base for flexible mounting options
• Automatic height compensation 20–35 mm
• Max. clamping force 2,000 N

Secure and consistent workholding for production use

This horizontal clamping solution offers repeatable clamping thanks to its robust kinematics and a specified maximum clamping force of 2,000 N, which ensures components remain stationary during machining or assembly. The design includes a variable open holding arm, enabling quick positioning of irregular or bulky parts without complex adjustment. Built-in adjustability reduces set-up time and helps maintain consistent cycle times on the shop floor.

Rapid height adjustment reduces set-up complexity

Featuring automatic height compensation (S = 20 mm) and a maximum compensating range of 35 mm, the device adapts to slight differences in workpiece height without manual shimming. This automatic compensation minimises the need for re-clamping and supports continuous operation across batches with variable stock thickness. The integrated pressure screw (M6 x 40) provides controlled actuation and reliable pressure application for repeatable results.

Compact angle base for flexible fixture construction

The angled base provides multiple mounting orientations, making it straightforward to integrate into custom fixtures or modular tooling plates. With a total length (L1) of 173 mm and defined interface dimensions such as B = 56 mm and E = 22 mm, the clamp fits tight assemblies while offering sufficient reach and clearance. The open holding arm configuration supports quick loading and unloading, improving throughput in assembly and inspection stations.

Practical adjustment range and workshop durability

Key adjustment values such as the clamping jaw range (C = 20–26 mm) and work height limits (HW min. -3 mm / HW max. 24 mm) make it simple to determine suitability for specific parts. The unit’s compact form and clearly defined interface dimensions facilitate predictable integration into existing tooling. With a packaging unit of 1, the product is delivered ready for installation in single-piece applications or as a spare part for maintenance.
