High Strength Bolts VS. Bolts
What are High Strength Bolts?
High-strength bolts are used in various applications in different industries because of their ability to provide security in heavy structural joints. High-strength bolting provides numerous benefits over regular bolts, with higher tensile strength they can withstand shear force which is common in applications like construction and heavy machinery.
The main difference between regular bolts and high-strength bolts is the manufacturing material and grading system. The American Society for Testing and Materials or ASTM is responsible for the standards of heavy hex structural bolts. The said standards are guidelines in the fabrication of materials to produce fasteners like high-strength bolts for specific applications.
What are examples of high-strength bolts?
There are several types of high-strength bolts, some can be customized according to the requirements of OEM-type applications. But the following are some types of high-strength bolts with their features.
Bolt Grade | Material | General Properties | Applications/Uses |
ASTM A325 | quenched Alloy steel / tempered Alloy steel | Tensile strength of 150,000 psi | Construction such as structural steel connections and heavy machinery |
ASTM A490 | quenched Alloy steel / tempered Alloy steel | Tensile strength of 180,000 psi | Used in extreme applications that require strength |
Grade 9 Bolts | Yellow zinc chromate | Tensile strength of 180,000 psi | Heavy machinery |
Grade 8 Bolts | Type 1 – medium carbon steel or alloy steel, or boron steel Type 2 – low carbon martensitic steel Type 3 – weathering steel | Tensile strength of 150,000 psi | Structural bolting project |
Additionally, high-strength bolts can have special coating or plating to enhance their qualities and effectiveness. This will also provide them extra protection from corrosion and failure.
Application Uses of High-Strength Bolts
Multiple industries that have a high necessity for high-strength bolts include the below:
- Construction and Infrastructure Industry:high-strength bolts are used in structural connections of buildings, bridges, and others.
- Automotive and Heavy Machinery Industry:high-strength bolts are mechanical components used in engines, automobiles, transmissions, bulldozers, and excavators.
- Aerospace Industry:high-strength bolts are essential devices in aircraft parts such as the wings and fuselage.
Here are some benefits of using high-strength bolts:
- High-strength bolts provide higher strength to withstand breakage from certain applications with the presence of high shear force.
- High-strength bolts are made of stronger materials like Alloy steel which offers increased reliability.
- High-strength bolts are resistant to corrosion and rust hence their increased durability and improved quality.
There are various applications of high-strength bolts because of their excellent quality and benefits. High-strength bolts are often considered in the most common application industries of construction, aerospace, and automotive. And because they offer benefits of increased strength, reliability, and durability they are valuable tool/device in the fastening industry.
