ISO 5713:1990 is an international standard developed by the International Organization for Standardization (ISO) that specifies the dimensions and characteristics of fixing bolts used in soil-working equipment. These bolts secure wear parts on agricultural machinery designed for soil preparation and cultivation. Established by the ISO Technical Committee 23 (Tractors and Machinery for Agriculture and Forestry), this standard ensures consistent quality, compatibility, and safety for critical fastening components in soil-working equipment.
By adhering to ISO 5713:1990, manufacturers and users benefit from standardized bolt types-each designed to meet mechanical requirements for durability and reliability in demanding field conditions. The standard covers three main types of fixing bolts, defining their dimensions, thread specifications, mechanical properties, and surface finishes.
Bolt Types and Dimensions ISO 5713:1990 details three primary designs of fixing bolts for soil working elements:
Mechanical Properties and Quality Grades Bolts must conform to mechanical performance standards specified in ISO 898-1, particularly class 8.8 and above, ensuring strength and durability under soil-working stresses.
Thread Specifications and Tolerances Metric thread tolerances follow ISO 965-3, tailored for construction thread grades to guarantee proper fit and interchangeability.
Surface Treatment and Protection The standard mandates that bolts are clean, corrosion-protected, and at minimum, greased to extend service life in abrasive and moisture-exposed environments.
Marking and Traceability Markings and identification details comply with ISO 898-1, facilitating quality assurance and traceability during manufacturing and usage.
ISO 5713:1990 fixing bolts are integral components in various agricultural and forestry machinery used for soil preparation tasks such as plowing, tilling, and harrowing. Applications include:
Using these standardized bolts helps minimize downtime, avoid mismatched components, and maintain consistent performance in demanding farming operations.
To fully implement ISO 5713:1990, knowledge and application of the following related ISO standards are important:
Adherence to these complementary standards provides a comprehensive framework for manufacturing, quality control, and utilization of fixing bolts in soil-working machinery.
ISO 5713:1990 establishes critical mechanical and dimensional requirements for fixing bolts used in soil-working equipment. It promotes standardization, reliability, and safety across agricultural and forestry machinery industries worldwide. By following this standard, manufacturers and users ensure that essential soil-working components are securely fastened with high-quality, durable bolts designed specifically to withstand harsh operational environments.
