AMF Screw Clamp Block Nr. 6400 - 52 — flat support, height 42–52 mm

AMF Screw Clamp Block Nr. 6400 - 52 is a compact clamping element designed for precise, repeatable fixation in production fixturing and workshop jigs; suitable where stable support and reliable thread-driven adjustment are required

• Flat support for secure clamping
• Height adjustable 42–52 mm
• Trapezoidal thread TR 30 x 4
• Max. load capacity 100

Consistent clamping accuracy for repetitive production

The clamp block offers a height-adjustable range (H min. 42 mm to H max. 52 mm) that enables fine vertical alignment when integrating into fixtures or machine tables. Thanks to the trapezoidal thread TR 30 x 4, movement is smooth and backlash is reduced compared with standard metric threads, which supports repeatable positioning during series work. This mechanical precision reduces set-up time and ensures that fixtures keep their reference points across repeat operations, improving throughput and process reliability.

Robust mechanics that simplify maintenance and integration

Constructed for workshop use, the component features equal-diameter mounting interfaces (D1: 50 mm, D2: 50 mm) that make it straightforward to seat and replace in modular clamping systems. The defined maximum load capacity (100) provides a clear performance threshold for design calculations and safety margins in jig construction. The screw-driven concept preserves clamping force under cyclic loads and requires minimal maintenance: routine inspection of the thread and lubrication keeps the unit operational with low downtime, supporting consistent production cycles.

Practical benefits for engineering and tooling teams

As a compact clamping element, the block reduces the complexity of bespoke fixtures while retaining flexibility for multiple part families. The flat support allows broad contact with workpieces where surface stability matters, while the screw adjustment enables controlled force application without relying on hydraulic or pneumatic systems. For engineering teams, integration is straightforward: the unit’s clear mechanical parameters permit fast CAD modelling and simple verification of clamping geometry, shortening the development loop for new jigs and reducing the iterative trial phase.

FAQ

What applications suit this clamp block best?
The AMF screw clamp block Nr. 6400 - 52 is intended for fixture and jig clamping in workshop and light industrial settings where a flat support and height adjustment (42–52 mm) are required for stable part positioning.

How is vertical adjustment achieved on this unit?
Vertical adjustment is provided via the trapezoidal thread (TR 30 x 4) built into the AMF screw clamp block, allowing controlled and repeatable movement between the specified height limits.

Which mounting dimensions must be considered when integrating the block into a fixture?
The block has two mounting diameters (D1: 50 mm and D2: 50 mm) that should be matched to locating bores or seats in the fixture layout to ensure secure installation.
