Some key points about hot-dip galvanized eye bolts
Hot-dip galvanized eye bolts boast high strength and excellent corrosion resistance, making them the preferred choice for power towers, signal towers, and highway guardrails in recent years. Today, we’d like to share some key information about hot-dip galvanized eye bolts. Let’s take a look!
With advances in technology, hot-dip galvanized eye bolts have found widespread use. Compared with stainless steel bolts, they are significantly more cost-effective while offering much higher strength. In fact, for outdoor installations, hot-dip galvanized eye bolts have largely replaced stainless steel bolts.

Causes and Solutions for Peeling on the Surface of Hot-Dip Galvanized Eye Bolts
The hot-dip galvanized eye bolt features a pure zinc outer layer and a zinc–iron alloy inner layer. This structure ensures superior durability, preventing peeling or flaking under normal use. However, no system is entirely foolproof; improper handling or inadequate maintenance can still lead to cracking of the hot-dip galvanized bolt. Today, we’ll explore the causes of outer‑layer failure in hot-dip galvanized eye bolts and how to address them.

Types and Applications of Hot-Dip Galvanized Pins
Hot-dip galvanized pins are a common material used in mechanical manufacturing. Their primary function is to secure internal components within machinery and to facilitate connections between these components, effectively “bridging” them together. Of course, hot-dip galvanized pins come in various types—cylindrical, slotted, safety‑type, and more. Below, we will provide a detailed and comprehensive description of this component.

What are the advantages of hot-dip galvanized pins?
The thickness of the zinc coating typically ranges from 5 to 15 micrometers, whereas the hot-dip galvanized coating generally exceeds 35 micrometers and can even reach 200 micrometers. It exhibits excellent coverage, a dense microstructure, and is free of organic inclusions. As is well known, the atmospheric corrosion resistance of zinc relies on both mechanical protection and electrochemical protection.

Introduction to Hot-Dip Galvanized Pins and Inspection Standards
Hot-dip galvanized pins are typically used to secure or position components. They generally come in two forms: cylindrical and conical. There are also two common installation methods: press‑fitting and driving in with a soft‑metal hammer. These pins are often tapered, featuring pointed tips, and are employed to fasten or affix materials such as wooden boards, tiles, shoe soles, uppers, furniture molds, and various parts, or to repair holes.

Selection Criteria for Hot-Dip Galvanized Flat Washers
The primary function of a hot-dip galvanized flat washer is to reduce the surface pressure exerted on the fastened component by increasing the bearing area of the screw head. This is because, when the surface pressure exceeds the material’s capacity, the bearing surface may deform or collapse, leading to loosening of the fastener. Consequently, particularly when fastening through elongated holes, if the contact area between the screw head and the workpiece is small—especially for soft materials such as aluminum or resin—the use of a hot-dip galvanized flat washer can help mitigate surface pressure to some extent.

Classification of Hot-Dip Galvanized Spring Washers
Hot-dip galvanized spring washers are commonly referred to as spring washers in the fastener industry. They are manufactured from stainless steel and carbon steel, with carbon steel being a type of iron. Standard sizes for spring washers typically include M3, M4, M5, M6, M14, and M16; these specifications are most widely used. The national standard GB/T 94.1‑87 specifies standard spring washers in sizes ranging from 2 to 48 mm, in accordance with GB/T 94.4‑85, “Technical Requirements for Elastic Washers and Spring Washers.”

What are the installation precautions for U-bolts?
U-bolts, also known as riding bolts, are non-standard fasteners so named for their U-shaped design. Both ends are threaded and can be paired with nuts. They are primarily used to secure tubular or sheet-like components, such as water pipes. Because their method of fastening resembles a rider mounted on a horse, they are commonly referred to as “riding bolts.” U-bolts have a wide range of applications, including construction and installation, mechanical assembly, and the automotive, marine, bridge, tunnel, and railway industries.

Specifications and Types of Hot-Dip Galvanized Bolts
Hot-dip galvanized bolts, also known as hot‑dip zinc‑coated bolts, are produced by first degreasing and derusting the bolt to obtain a clean, well‑wetted surface, then immediately immersing it in a bath of molten zinc that has been preheated. This process forms a zinc coating on the bolt’s surface. The coating is relatively thick—typically 30 to 60 micrometers—and exhibits excellent corrosion resistance. It is ideally suited for long‑term rust protection of steel components exposed to outdoor conditions, such as highway guardrails, power transmission towers, and large‑size fasteners—items that tend to be relatively “rough” in texture. Owing to their high strength and superior corrosion resistance, hot‑dip galvanized bolts have increasingly become the material of choice for power transmission towers, communication towers, and highway infrastructure.

Factors Affecting the Price of Hot-Dip Galvanized Bolts
Hot-dip galvanized bolts, also known as hot‑dip zinc‑coated bolts, are bolts that have undergone a hot‑dip galvanizing process, giving them excellent corrosion resistance. The zinc coating on these bolts is relatively thick—typically 30 to 60 micrometers—providing superior protection against rust. They are well suited for outdoor steel components, such as highway guardrails, power transmission towers, and large‑size fasteners, offering long‑term corrosion protection for more “rough” or heavily exposed parts. Thanks to their high strength and outstanding corrosion resistance, hot‑dip galvanized bolts are increasingly used in power transmission towers, communication towers, and highway guardrail systems.
