BREAKING LOADS FOR BOLTS WITH REDUCED LOAD CAPACITY
Introduction
Bolts are essential components in many mechanical and structural applications. However, the shape and design of bolts can significantly affect their load capacity. Bolts with reduced sections, deep threads, or special geometries may have lower breaking loads compared to standard bolts. This document analyzes the mechanical characteristics of such bolts and provides guidance on how to choose and use these bolts effectively.
Breaking Loads for Bolts with Reduced Sections
Bolts with reduced sections have a smaller resistance area, which results in lower breaking loads. Tensile strength and hardness are key parameters for assessing the load capacity of these bolts.
Table: Breaking Loads for Bolts with Reduced Sections
| Type of Bolt | Material | Nominal Diameter (mm) | Resistance Area (mm²) | Breaking Load (N) |
| Reduced Section Bolt 1 | Carbon Steel | 5 | 14.2 | 1200 |
| Reduced Section Bolt 2 | Stainless Steel | 5 | 13.8 | 1100 |
| Reduced Section Bolt 3 | Aluminum Alloy | 5 | 13.5 | 700 |
| Reduced Section Bolt 4 | Titanium | 5 | 13.7 | 1400 |

The graph shows how the resistance area affects the breaking load of bolts with reduced sections.
Bolts with Deep Threads
Bolts with deep threads have a larger surface area, but the depth of the threads can weaken the bolt, reducing its breaking load.
Table: Breaking Loads for Bolts with Deep Threads
| Type of Bolt | Material | Thread Depth (mm) | Breaking Load (N) |
| Deep Thread Bolt 1 | Carbon Steel | 2.0 | 1300 |
| Deep Thread Bolt 2 | Stainless Steel | 2.2 | 1150 |
| Deep Thread Bolt 3 | Aluminum Alloy | 1.8 | 750 |
| Deep Thread Bolt 4 | Titanium | 2.1 | 1500 |

Conclusion
Bolts with special shapes and designs, which have reduced load capacities, present a unique challenge in mechanical engineering. However, with the correct selection of materials and treatments, it is possible to optimize the performance of these bolts for specific applications. Companies investing in high-quality bolts can ensure secure and durable fastening, reducing the risks of failure and increasing the reliability of their products.
For companies looking to improve the quality and efficiency of their production processes, collaborating with experienced suppliers is crucial. A competent supplier can offer technical advice on choosing the most suitable materials for each specific application. The right choice of bolt, combined with correct installation techniques, can make the difference between a reliable product and one prone to failure.
