Introduction to Fasteners - Bolt & Nuts
Fasteners are indispensable hardware devices essential for securely joining two or more objects. Revered for their non-permanent joining capabilities, fasteners are fundamental in a myriad of applications ranging from high-end industrial machinery to everyday household repairs. Among these, bolts, nuts, and their accompanying accessories such as washers and anchors form the core.
At Kirthika, we extend a comprehensive range of bolts and nuts to cater to diverse needs, ensuring durable and robust assembly in various contexts. Our extensive collection includes structural bolts, machine screws, wedge anchors, washers, and rivets, designed meticulously to fulfill specific requirements in terms of strength, function, and resilience.
Varieties of Fasteners
1. Structural Bolts
Structural bolts are engineered to offer exceptional strength and reliability, primarily used in heavy-duty applications including construction, bridges, and other structures subject to substantial stress.
- High-Tensile Strength: Manufactured from high-grade steel, these bolts can withstand significant forces without deforming or failing.
- Corrosion Resistance: Many structural bolts come with coatings like galvanization to resist corrosion and rust, thus extending their lifespan.
- Precision Engineering: They are made to precise measurements to ensure a perfect fit and optimal performance in structural applications.
2. Machine Screws
Machine screws are smaller than structural bolts but equally critical, mainly used in machinery, electronics, and detailed assembly work.
- Variety of Heads: Available with different head types such as flat, round, and pan heads to suit diverse applications.
- Thread Precision: These screws typically have precise, uniform threads for managing assemblies that demand high levels of accuracy.
- Materials: They are available in various materials including stainless steel, alloy steel, and brass, tailored to specific applications.
3. Wedge Anchors
Wedge anchors are crucial for anchoring objects into concrete, known for their holding power and ease of installation.
- High Load Capacity: Specifically designed to support heavy loads and provide a strong, permanent hold in concrete.
- Ease of Installation: Mechanically expanding as they are installed, wedge anchors provide reliable, high-strength holds with minimal effort.
- Corrosion Protection: Often available with coatings that guard against corrosion, making them suitable for both indoor and outdoor applications.
4. Washers
Washers are typically used with bolts and nuts to distribute the load, prevent damage to the surfaces being joined, and reduce the loosening that happens due to vibration.
- Variety of Types: Including flat washers, lock washers, and spring washers, each serving a specific purpose.
- Material Options: Available in multiple materials such as steel, stainless steel, and nylon, each chosen based on the environmental and load conditions.
- Surface Protection: Some washers come with surface treatments to increase durability and prevent corrosion.
5. Rivets
Rivets provide a permanent solution for fastening two pieces of material together, mainly used where welding isn't feasible.
- Durability: Known for creating strong joints that can withstand high stresses and loads.
- Varied Applications: Used in a plethora of applications from aircraft manufacturing to electronic hardware.
- Materials: Available in aluminum, steel, and copper, providing flexibility in terms of strength, weight, and corrosion resistance.
