### 1. **Material: Galvanized Carbon Steel** - **Base Material - Carbon Steel**: The core of these bolts is made from carbon steel, which offers excellent strength properties. Carbon steel provides a robust foundation, making it suitable for applications that require high load - bearing capabilities. Different grades of carbon steel can be selected based on the specific requirements of the project, with higher carbon content generally resulting in greater strength but potentially reduced ductility. - **Galvanization Process**: The carbon steel bolts undergo a galvanization process. This involves coating the bolts with a layer of zinc, either through hot - dip galvanization or electro - galvanization. Hot - dip galvanizing, the more common method, immerses the bolts in a bath of molten zinc. This creates a thick, durable zinc coating that forms a metallurgical bond with the steel substrate. The zinc coating acts as a sacrificial barrier, protecting the underlying carbon steel from corrosion. Even if the zinc layer is scratched or damaged in some areas, it will still corrode preferentially to the carbon steel, thus extending the lifespan of the bolt. Electro - galvanization, on the other hand, deposits a thinner layer of zinc through an electrochemical process, which is more suitable for applications where a thinner, more precise coating is required. ### 2. **Design Features** - **Long Flange Screw Structure**: - **Integrated Flange**: These bolts feature an integrated flange, which is a wide, flat, washer - like projection at the head of the bolt. The flange serves multiple purposes. It increases the bearing surface area, distributing the clamping force more evenly over the fastened material. This is especially beneficial when working with softer or thinner materials, as it helps prevent the bolt from sinking or causing damage. For example, in wood or thin sheet metal applications, the flange can prevent the bolt from pulling through the material. Additionally, the flange can act as a locking mechanism in some cases, reducing the likelihood of the bolt loosening due to vibration. - **Lengthened Shank**: The shank of these bolts is designed to be longer than standard bolts. This extended length makes them ideal for applications where there is a need to fasten through multiple layers of material or into thick substrates. For instance, in construction projects, when joining thick steel beams or when attaching components to a deep - set structure, the extra length ensures a secure connection. The length of the shank can be customized according to specific project requirements, ranging from a few inches to several feet, depending on the application. - **Extended Hex Head**: - **Enhanced Torque Application**: The hex head of these bolts is extended in size compared to regular hex - head bolts. This larger head provides more surface area for tools such as wrenches or sockets to grip. As a result, it allows for greater torque to be applied during installation and removal. In situations where a high - strength connection is required, being able to apply more torque ensures that the bolt is tightened securely. This is crucial in applications such as heavy machinery assembly, where vibrations and high - stress loads are common. - **Easier Access in Tight Spaces**: The extended hex head also makes it easier to access and turn the bolt in tight or hard - to - reach areas. In complex machinery or equipment with limited clearance, the larger head can be more easily engaged with a tool, reducing the difficulty of installation and maintenance. ### 3. **Finish: Plain Finish** - **Aesthetic and Functional Aspect**: The plain finish on these bolts gives them a simple, uncoated appearance. While it may not offer additional corrosion protection beyond the galvanized layer, it can be advantageous in certain applications. In some industrial settings where a clean, non - reflective surface is preferred, the plain finish can help reduce glare. Additionally, in applications where the bolt will be painted or coated with another protective finish later, the plain finish provides a good base for adhesion. The lack of an additional top - coat finish also means that there is no risk of the top - coat peeling or flaking off over time, which could potentially cause problems in the connection. ### 4. **Wholesale Availability** - **Bulk Quantity Options**: These galvanized carbon steel long flange screws with extended hex heads are available for wholesale purchase. This makes them suitable for large - scale projects, such as construction companies building multiple structures, manufacturing plants assembling large quantities of products, or maintenance departments that need to stock up on fasteners for regular equipment servicing. Wholesale buyers can typically order in quantities ranging from hundreds to thousands of bolts, depending on their needs. - **Cost - Efficiency for Bulk Purchases**: Buying in wholesale quantities often comes with cost savings. Suppliers are able to offer more competitive pricing per unit when selling larger volumes. This cost - efficiency allows businesses to manage their project budgets more effectively. For example, a construction firm that needs a large number of these bolts for a new building project can save a significant amount of money by purchasing them wholesale rather than in smaller, retail - priced quantities. ### 5. **Applications** - **Construction Industry**: In construction, these bolts are used for a variety of purposes. They can be used to fasten structural steel components together, such as in the construction of buildings, bridges, and industrial facilities. The long shank and strong carbon steel material can withstand the heavy loads and vibrations experienced in these structures. Additionally, the galvanized coating protects against corrosion, which is especially important in outdoor construction projects where the bolts are exposed to the elements. They can also be used to attach wooden or metal panels to frameworks, providing a secure and durable connection. - **Industrial Machinery and Equipment**: In industrial settings, these bolts are used in the assembly and maintenance of machinery. The extended hex head allows for easy installation and removal, even in tight spaces within the machinery. The long flange screw design ensures a stable connection, which is crucial for machinery that operates under high - stress conditions. For example, in manufacturing plants, they can be used to secure conveyor belts, motors, and other components to their mounting frames. - **Automotive and Transportation**: In the automotive and transportation industries, these bolts can be used in the assembly of vehicles, trailers, and transportation equipment. They can be used to fasten body panels, engine components, and chassis parts. The corrosion - resistant properties of the galvanized carbon steel are important in these applications, as vehicles are often exposed to moisture, road salt, and other corrosive elements.
