End gauge 125 mm (M320.125.0) — Gauge block, Grade 0, DIN EN ISO 3650, Metav IndustryLine

A 125 mm gauge block (M320.125.0) engineered as a high‑precision length reference for workshop and laboratory inspection tasks, complying with the DIN EN ISO 3650 standard.

• DIN EN ISO 3650 Grade 0 accuracy
• Hardened special steel construction
• Cross-section 35 x 9 mm for enhanced stability
• Nominal length 125 mm for widespread calibration use

Dependable reference for routine and accredited checks

The gauge block offers a consistent reference length of 125 mm, suitable for both routine shop-floor checks and integration into formal measurement procedures. Manufactured from special steel, hardened, the bar resists superficial deformation and maintains form under typical handling, which leads to fewer re-measurements and higher process uptime. Compliance with DIN EN ISO 3650 and the designation Grade 0 indicate a level of geometric tolerance that supports reliable comparison measurements and length setting on comparators and optical benches.

Stability and handling that reduce measurement uncertainty

With a compact cross-section of 35 x 9 mm and a mass of 0.4 kg, the block balances rigidity with manageable handling. The chosen profile reduces bending and thermal drift during short inspection cycles, contributing to reproducible results across repeated measurements. The hardened surface reduces wear from frequent wringing or stacking with other blocks, extending the usable lifetime and sustaining the declared accuracy over time.

Clear standardisation for traceability and process control

Engineered to meet DIN EN ISO 3650, this precision block supports traceable workflows and quality assurance routines where standard conformity is required. The Grade 0 classification places the block within a narrow tolerance band, making it suitable as a reference piece for setting gauges, calibrating instruments and verifying fixtures. The simple, well-documented specification also simplifies inclusion in internal quality records and measurement uncertainty calculations.

Practical integration into inspection benches and sets

The 125 mm length is a practical choice for workshop and laboratory sets, bridging smaller reference blocks and longer standards to cover a broad measurement range without unnecessary inventory complexity. The special steel, hardened construction allows safe pairing with other hardened blocks and accessories while reducing the risk of transfer wear. Where rapid, repeatable alignment is required, the block’s dimensions and finish permit efficient wringing and stacking with complementary gauges.

FAQ

What accuracy class does this gauge block conform to?
The block is specified as Grade 0 according to DIN EN ISO 3650, providing a narrow tolerance suited for precise reference tasks.

Which material is used and what are the benefits for measurement tasks?
Manufactured from special steel, hardened, the M320.125.0 offers enhanced surface hardness and wear resistance, which preserves dimensional stability during frequent use.

Is the 125 mm length suitable for workshop calibration sets?
Yes, the 125 mm nominal length fits well between smaller reference blocks and longer standards, making it a versatile element in calibration kits and inspection benches.

How does the cross-section influence measurement reliability?
The 35 x 9 mm profile increases rigidity and reduces bending, which lowers measurement uncertainty during short-term checks and repeated handling.

Can this block be used together with other hardened blocks?
The hardened finish and standard geometry make the block compatible for wringing and stacking with other hardened gauge blocks in Grade‑compatible sets.
