Double end threaded rods are manufactured in various materials, including stainless steel, alloy steel, and even plastic, providing options for different environments and loading conditions. Stainless steel rods, for instance, offer excellent corrosion resistance, making them ideal for marine applications or places where moisture is a concern. On the other hand, alloy steel rods may be preferred in settings requiring enhanced strength and capacity to withstand high loads.
Butterfly screws, also known as toggle bolts, are a type of fastener that features a pair of wings that fold during installation and expand once they are inside a pre-drilled hole. The design allows for a stronger grip on hollow walls, such as drywall, where regular screws might not provide sufficient anchoring. Butterfly screws are particularly useful for mounting heavier items like televisions, where the risk of falling can be a significant concern.
Washer head machine screws are characterized by their broad, flat heads that resemble a washer. This design provides a larger bearing surface than standard screws, which helps distribute the load more evenly across the material being fastened. The head’s geometry often includes a recessed area for a driver, facilitating easy installation and removal. Additionally, these screws are typically made from high-strength materials such as stainless steel, carbon steel, or alloy steel, ensuring durability and resistance to corrosion and wear.
The body of a hex head bolt features external threads that engage with a corresponding nut or a tapped hole, allowing for a secure and adjustable connection. Depending on the intended application, these bolts can be made from various materials, including steel, stainless steel, and even plastic, each offering different levels of strength, corrosion resistance, and weight considerations.
