Hexagon thin nut DIN439
- Product description：Hexagon thin nut with thread specification of m1.6-m64, performance grade of 14h, 04, 05, a2-035, a2-025, a4-035, a4-025, Cu2, cu3 and AL4, product grade of a and B.
Hexagon thin nut DIN439
Material: stainless steel 304316, grade 8.8 high strength and grade 12.9 high strength
Product standard:DIN439
It can also support non-standard customization.
Range: M1.6～M64. It covers a variety of sizes from small to large diameters, meeting the needs of different application scenarios.
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.
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 \(D ＞ 16mm\).
-
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.
-
"螺紋規格" is translated as "Thread Size" (industry-standard term for fastener thread specifications, avoiding ambiguity with "Thread Specification").
-
"性能等級" uses "Property Classes"—the official term in ISO/DIN fastener standards, distinguishing it from "Strength Classes" (more commonly used for bolts).
-
"產品等級" 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.
