        1. Thread Size

        Range: M1.6~M64. It covers a variety of sizes from small to large diameters, meeting the needs of different application scenarios.

        2. Property Classes

        Including classes 14H, 04, 05, A2-035, A2-025, A4-035, A4-025, CU2, CU3, and AL4.
        • 14H: Represents a high-precision thread class.
        • 04, 05: Carbon steel property classes.
        • A2/A4 series (e.g., A2-035, A2-025): Stainless steel property classes.
        • CU series (e.g., CU2, CU3): Copper alloy property classes.
        • AL4: Aluminum alloy property class.

        3. Product Grades

        Divided into Grade A and Grade B:
        • Grade A: Applicable to nuts with a nominal thread diameter \(D ≤ 16mm\).
        • Grade B: Applicable to nuts with a nominal thread diameter \(D > 16mm\).

        4. Appearance and Dimensions

        • Shape: Hexagonal (six-sided), with a relatively thin thickness—this makes it well-suited for applications where space is limited.
        • Specific dimensional parameters (e.g., width across flats, thickness): Determined in accordance with the provisions of the DIN 439 standard. Different thread sizes correspond to different specific dimensions.

        Key Notes on Technical Terminology

        • "螺紋規(guī)格" is translated as "Thread Size" (industry-standard term for fastener thread specifications, avoiding ambiguity with "Thread Specification").
        • "性能等級(jí)" uses "Property Classes"—the official term in ISO/DIN fastener standards, distinguishing it from "Strength Classes" (more commonly used for bolts).
        • "產(chǎn)品等級(jí)" is rendered as "Product Grades" to align with DIN 439’s classification of dimensional accuracy (Grade A for higher precision, Grade B for general precision).
        • "對(duì)邊寬度" (a critical dimension of hexagon nuts) is translated as "Width across flats"—the universal engineering term for the distance between two opposite hexagon faces.
