Carbon Steel Lifting Eye Bolts
Product Overview
Carbon steel lifting eye bolts are heavy-duty threaded fasteners with a forged circular head, designed for lifting, hoisting, and rigging applications. Engineered to provide reliable load-bearing capabilities, these bolts are commonly used in machinery anchoring, structural support systems, and industrial lifting operations. With durable carbon steel construction and optional surface coatings such as hot-dip galvanizing or black oxide, they ensure long service life under dynamic and static load conditions.

Material and Manufacturing Process
Carbon steel lifting eye bolts are forged from premium-grade carbon steel, such as C1045 or Q235, offering both tensile strength and ductility. The production process involves:
Raw material testing (chemical and mechanical)
Hot forging of the eye head and shank
Precision thread rolling or cutting
Surface treatment (hot-dip galvanizing, blackening, or plain finish)
Load testing per batch
Final inspection and laser marking (if needed)
The forged structure ensures strength continuity across the bolt head and shank, making it safe for vertical and angled loading.
Typical Applications and Industries
Carbon steel lifting eye bolts are widely used in industries such as:
Heavy machinery and equipment lifting
Shipbuilding and marine rigging
Steel structure construction
Wind turbine maintenance
Transportation and logistics
Mining and oilfield applications
They are particularly effective in scenarios requiring frequent lifting or secure anchoring of heavy parts.
