Manufacturing & testing
The selected wrench pages describe heat treatment, forging/assembly, automatic polishing and nickel-nickel-chromium mirror plating. The base steel grade and process acceptance criteria are not provided.
Before approval, agree the jaw-opening check, L/W2 measurement method, fit and torque test. This is buyer guidance, not evidence of a test performed by Atlas.
Corporate certification statements do not demonstrate current coverage for these wrench models. Ask for the current holder, validity dates, factory address and product scope.
Technical & quality documents
These are public-document leads. Current certificate validity and product applicability have not been independently established.
Product dimensions and packing
Both item pages provide dimensional and box/carton tables. No model-specific steel grade or numeric torque test report was confirmed.
Before approval
Request the controlled drawing, material specification and inspection limits.
Management and product documents
The company profile lists management and product-related marks. No current certificate acceptance is claimed here.
Before approval
Check the actual certificate, issuer, validity and coverage; do not apply measuring-tool approvals to wrenches.
