TECWERK precision straight edge DIN 874/00, 300 mm — hardened stainless steel, 38 x 8 mm cross section

TECWERK precision straight edge DIN 874/00, 300 mm is a workshop reference tool for inspection and layout work, designed for reliable flatness checks and transfer measurements in production and quality assurance

• Hardened and ground stainless steel blade
• Lapped measuring edges for accurate references
• Hand‑heat shield reduces thermal distortion
• Non‑glare matt finish for clear visibility

Accurate, traceable reference measurements for quality control

A hardened, flat reference blade ensures repeatable accuracy when checking surfaces and setting up machinery. The lapped measuring edges provide a true line that reduces measurement uncertainty and simplifies comparison tasks against production parts. Conformity with DIN 874 means the instrument serves as a validated workshop standard, supporting inspection workflows that require documented reference tools. This stability reduces rework and speeds up in‑line checks.

Built for everyday workshop resilience and corrosion resistance

The blade is manufactured from stainless steel, hardened and ground to sustain frequent handling without losing accuracy. The 38 x 8 mm cross section balances rigidity and handling convenience, allowing stable placement across small components as well as longer checks along machined edges. The matt, non‑reflective surface minimises glare under workshop lighting, improving visual contrast when comparing surfaces or using optical aids.

Lower thermal influence and comfortable handling during repeated use

Equipped with a hand‑heat shield, the straight edge limits the transfer of body heat to the measuring surface, which helps to preserve dimensional integrity during repeated checks. Reduced thermal drift is particularly beneficial in temperature‑sensitive routines and when working with fine tolerances. The overall design supports confident positioning and reduces the risk of measurement error caused by handling.

Inspection readiness and integration into QA processes

The tool is designated inspection required, ensuring it can be entered into calibration and traceability systems as part of quality assurance. As a compact, standardised reference complying with DIN 874, it integrates smoothly into calibration schedules and inspection documentation. The robust finish and lapped edges maintain performance between formal checks, delivering a reliable reference for workshop and inspection tasks.

FAQ

What materials is the straight edge suitable for checking?
The precision straight edge is intended as a reference tool for inspecting machined surfaces and can be used when checking components made from metals and other solid materials where a flatness reference is required.

How does the hand‑heat shield improve measurement reliability?
The hand‑heat shield reduces heat transfer from the operator to the blade, helping the straight edge maintain its dimensional stability during repeated handling and so preserving measurement accuracy.

Is the tool compliant with any standards?
Yes, the instrument is produced to the requirements of DIN 874/00 and is suitable as a workshop reference for inspection tasks that require standardised measuring equipment.

How often should the measuring edges be checked or re‑lapped?
Edge checking intervals depend on usage and inspection schedules; the product is marked inspection required so it should be included in regular calibration and verification cycles according to internal quality procedures.
