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

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

Conclusion
Screws with special shapes and designs, which have a reduced load capacity, pose a unique challenge in mechanical engineering. However, with the correct selection of materials and treatments, it is possible to optimize the performance of these screws for specific applications. Companies that invest in high-quality screws can ensure secure and durable fastening, reducing the risk of failures and increasing the reliability of their products.
For companies looking to improve the quality and efficiency of their production processes, it is essential to collaborate with experienced suppliers who can offer high-quality, customized solutions. A competent supplier can provide technical advice on choosing the most suitable materials for each specific application. Selecting the right type of screw, combined with a proper understanding of installation techniques, can make the difference between a reliable product and one prone to failure.
