Bolts are high-strength threaded fasteners used to create secure bolted joints by applying axial clamping force together with a nut. Designed to resist both tensile and shear loads, bolts are widely used in structural, mechanical, and industrial applications across multiple sectors.
Overview
Bolts are threaded fasteners primarily used together with nuts to form bolted joints. In a bolted connection, the nut applies axial clamping force while the bolt shank helps resist shear forces, ensuring joint stability and structural integrity.
Function & Working Principle
- The nut tightens onto the bolt to generate axial clamping force
- The bolt shank acts as a dowel to resist lateral (shear) forces
- Creates a strong, removable, and reliable mechanical joint
Design & Construction
- Externally threaded cylindrical shank
- Available with hex head, square head, countersunk head, or special heads
- Can be fully threaded or partially threaded depending on application
Materials
- Carbon Steel
- Alloy Steel
- Stainless Steel
Performance Characteristics
- High tensile and shear strength
- Reliable load distribution in bolted joints
- Suitable for high-pressure and high-temperature environments
- Reusable and easy to assemble or dismantle
Applications
