High-Quality Square Nut for Industrial Use
Product Overview
 | Square welded nuts standard Square welded nuts are a commonly used fastener, playing an important role in various mechanical devices and structures. The standards for square welded nuts mainly include appearance quality, dimensional accuracy, material requirements, and mechanical properties. In terms of appearance quality, the standards stipulate that the surface of the nuts must be free from cracks, bubbles, slag inclusions, and other defects to ensure a smooth appearance. Regarding dimensional accuracy, the standards specify the tolerance ranges for various dimensions such as the thread size, thread length, and thread profile of the nuts to ensure the fitting accuracy with bolts. In terms of material requirements, the standards outline the types of materials, chemical composition, and mechanical properties required for the nuts to ensure the reliability and durability of the materials. |
