Hardware tool accessories Hot-Bent Eye Bolt - Video

"Hot-bent eye bolts" typically refer to standard eye bolts (also known as eye screws or lifting eye screws). The term "hot bending" denotes a key manufacturing process used in their production. Eye bolts are common hardware components, primarily consisting of a threaded shank and a circular (or "sheep's eye")-shaped head.

**Alternative Names:** Depending on their specific shape or intended application, they are also referred to as eyelets, eye rings, eye pins, eye screws, fish-eye bolts, lifting eye screws, etc.

**Structure:** They consist of a threaded shank and a circular hook designed for suspension; the ring typically features an open gap.

**Materials:** The most common materials are carbon steel (e.g., Q235, 45# steel) and stainless steel (e.g., 304, 316); specialized materials, such as alloy steel, are also available.

**Surface Treatment:** Depending on requirements for corrosion resistance and the intended operating environment, various surface treatments—such as electro-galvanizing, hot-dip galvanizing, polishing, or electrostatic powder coating—may be applied. During the manufacturing process, specific sections of the metal stock (typically round steel bars or wire rods) are heated to high temperatures—ranging from 900°C to 1050°C—using methods such as induction heating. Once the metal has softened, it is formed into the desired shape in a single operation using a die within a large hydraulic press; the bending action is completed before the material cools to relieve internal metal stresses.
