Bolts are an omnipresent component in various industries, playing a crucial role in connecting and fastening structures. However, have you ever wondered about the significance of those grade markings? In this article, we delve into the performance grades of bolts and screw threads.

Performance Grades of Bolts

Bolts used in steel structure connections come in various performance grades, numbering more than ten, including 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, and 12.9. Bolts rated 8.8 and higher are crafted from low-carbon alloy steel or medium-carbon steel, treated through heat processes, and are commonly known as high-strength bolts. The rest are typically referred to as ordinary bolts. The grade markings on bolts consist of two figures, representing the nominal tensile strength value and the yield strength ratio of the bolt material.

For instance, a bolt with a performance grade of 4.6 signifies that the nominal tensile strength of the bolt material reaches 400 MPa, and the yield ratio is 0.6. In contrast, a high-strength bolt marked as 10.9 attains even greater strength after heat treatment, with a nominal tensile strength of 1000 MPa and a yield ratio of 0.9, achieving a nominal yield strength of 900 MPa.

It’s important to note that the bolt performance grade is an internationally recognized standard. Bolts with the same performance grade exhibit uniform performance characteristics, regardless of their material or origin. Consequently, when designing structures, engineers rely on the performance grade as the key parameter.

In the realm of bolts, strength is typically expressed as “X.Y,” where X * 100 equals the tensile strength, and X * 100 * (Y/10) equals the yield strength, given that yield strength/tensile strength equals Y/10, following standard identification regulations.

Performance Grades of Screw Threads

Screw threads are integral to countless applications, characterized by their uniform spiral profiles on solid surfaces, both internal and external. They can be classified into three primary categories based on their structural features and intended use.

Common Screw Thread: Featuring a triangular tooth profile, common threads are primarily used for connecting or fastening components. These threads come in coarse and fine variations, with fine threads offering enhanced connection strength.

Transmission Screw Thread: Transmission threads encompass trapezoidal, rectangular, sawtooth, and triangular tooth profiles, serving specific transmission purposes.

Sealing Screw Thread: Reserved for sealing connections, this category includes pipe threads, taper threads, and taper pipe threads.

The concept of thread fit refers to the degree of looseness or tightness between threaded components. Thread fit grades are defined by a combination of deviation and tolerance on both internal and external threads.

For instance, in the unified inch system, external threads have grades 1A, 2A, and 3A, while internal threads have grades 1B, 2B, and 3B. The higher the grade, the tighter the fit. Grade 1A and 1B offer loose tolerances, suitable for less critical applications, while grade 3A and 3B provide a tight fit suitable for safety-critical designs.

In metric threads, external threads are categorized as 4h, 6h, and 6g, while internal threads are categorized as 5H, 6H, and 7H, each with distinct applications based on their tolerance zones.

Thread Markings

Understanding thread markings is essential when dealing with fastener components:

Major Diameter/Tooth of Outer Diameter (d1): Represents the nominal diameter of the thread size.

Minor Diameter/Tooth Root Diameter (d2): Denotes the diameter where the thread root coincides.

Tooth Pitch (p): Refers to the axial distance between adjacent teeth on the meridian. In the imperial system, pitch is measured in teeth per inch, equivalent to 25.4mm.

Metric and Inch Self-Tapping Screws: These screws come in various specifications and pitches, allowing for precise applications.

In summary, understanding the grade markings of bolts, screws, and screw threads is vital, as different grades and markings indicate distinct applications and functions of bolts with different types in various industries and structures. Whether it’s for high-stress steel connections or precise threading requirements, these markings provide essential information for engineers and manufacturers alike.

Spring washers play a crucial role in mechanical assemblies, primarily by preventing nuts from loosening. Positioned beneath the nut, they find widespread application in both load-bearing and non-load-bearing structures of general mechanical products. What sets spring washers apart is their affordability, ease of installation, and suitability for components subjected to frequent assembly and disassembly.

Key Functions of Spring Washers

The fundamental purpose of a spring washer is to counteract loosening by applying force once screws and bolts are tightened. It accomplishes this by generating friction between the screw or bolt and the material it secures. During vibrations, this friction prevents the screw or bolt from coming loose. In cases where a cotter pin is inserted into the hole of a screw, the slotted hex nut is employed to prevent automatic nut loosening. This configuration is especially useful in situations involving vibration loads or alternating loads.

Another important role of spring washers is their collaboration with three screw and bolt assemblies, often used in conjunction with flat washers.

The Anti-Loosening Mechanism of Spring Washers

Spring washers function based on an anti-loosening principle. When compressed, they produce continuous elastic force, generating friction between the nut and the threaded connection of the bolt. This friction creates torque, which prevents the nut from loosening. Simultaneously, the sharp edge at the opening of the spring washer embeds itself into both the bolt’s surface and the connected piece, preventing relative rotation between the bolt and the connected component.

Varieties of Spring Washers

Wave Spring Washers

WG Type and WL Type Wave Washers: These open spring washers can be installed in tight spaces, making them ideal for applying prestress to bearings, reducing bearing noise, and enhancing operational accuracy and stability. They also find extensive use in electronic appliances. Materials commonly used include carbon steel, stainless steel, and copper alloys.

WN Type Wave Washer: This multi-layer wave crest overlapping spring washer is composed of multiple layers of material, designed for situations requiring substantial elastic force and uniform force release throughout the working stroke.

Disc Spring Washer

DIN6796 Disc Spring Washer: Compliant with DIN 6796 standards, this lock washer is used in medium to high-strength bolt and screw connections. It bears significant loads and possesses strong elastic recovery force, capable of withstanding wear, thermal expansion, contraction of wear parts, or seal compression. Disc spring washers can effectively replace ordinary spring washers but are not suitable for use in combination with wedge lock washers and flat washers.

Internal Tooth Spring Washer and External Tooth Spring Washer

These spring washers feature sharp, elastic teeth around their circumference, which press against bearing surfaces to prevent fastener loosening. The internal tooth elastic washer is used beneath screws with small head sizes, while external tooth spring washers are commonly placed under bolt heads and nuts. Toothed spring washers are smaller than conventional spring washers and evenly distribute stress on fasteners, ensuring reliable anti-loosening. However, they are not ideal for parts that require frequent disassembly.

Causes of Spring Washer Breakage

Several factors can contribute to the breakage of spring washers:

Expansion Ring: The spring washer’s expansion ring experiences radial outward tension resulting from the axial clamping force generated by tightening torque.

External Chamfer: A nut-bearing surface’s external chamfer can generate a radial component from the axial clamping force, causing the spring washer’s opening to expand. Smaller chamfer diameters increase the likelihood of expansion ring occurrence.

Flat Washer: Placing a flat washer between the nut and spring washer can help prevent expansion ring formation. However, excessively thin or soft flat washers may not be effective.

Hydrogen Embrittlement: This issue typically arises due to an inadequate heat treatment process and the failure to conduct timely hydrogen removal treatment after zinc electroplating.

Conclusion

This article provides valuable insights into the world of spring washers, encompassing their primary functions, anti-loosening mechanisms, various types, and potential causes of breakage. Armed with this knowledge, individuals can harness the full potential of spring washers in their applications, ensuring optimal performance and reliability.
