INSIZE Angle Plate KATOWNIK 100×70 MKSA Class 0 (MPN 4791-100)

INSIZE Angle Plate KATOWNIK 100×70 MKSA Class 0 is a precision angle plate engineered to provide true 90° reference surfaces for positioning, inspection and layout tasks in workshops and metrology labs. With nominal face dimensions of 100×70 in MKSA units and manufactured to Class 0 accuracy, this angle plate delivers stable support for workpieces and fixtures when high-precision squaring and alignment are required. The robust construction and machined reference faces make it suitable for repeated use as a datum during setup, inspection, and assembly operations.

Advantages

This Class 0 angle plate offers high geometric accuracy and repeatability for critical alignment and inspection work. Precisely ground faces ensure consistent 90° squaring and low deviation between surfaces. The plate’s rigid build reduces flex under normal clamping loads, providing stable support for measurement and machining reference tasks. As a standardized metrology accessory, it integrates easily into layout, fixture, and inspection workflows.

Suitable for

• Squaring and alignment of parts and fixtures
• Dimensional inspection and layout in workshops and quality control
• Fixture setup and tooling alignment for machining operations
• Use as datum surfaces during assembly and metrology procedures

Key specifications

• Nominal reference face dimensions: 100 × 70 (MKSA units)
• Accuracy class: Class 0 (high precision)
• Material: hardened and ground metal construction for stable reference faces
• Reference surfaces: precisely machined and ground 90° faces
• Intended use: precision positioning, squaring, and inspection

How to use

Place the angle plate on a stable surface or surface plate and ensure it is clean and free of debris before use. Position the workpiece or fixture against the machined faces to establish the 90° reference, and secure with appropriate clamps or fasteners while avoiding excessive force that could distort the assembly. Use measuring instruments such as dial indicators, height gauges or CMM probes relative to the plate’s faces to perform alignment and inspection tasks. After use, clean the faces and store the angle plate in a dry, protected location to preserve accuracy.

Usage recommendations

Verify cleanliness and inspect the reference faces before critical measurements; avoid hammering or over-tightening clamps against the plate. For best results, use on a calibrated surface plate and incorporate routine calibration checks into quality control procedures.
