ASME/ANSI B18.15:1985 Type 1 Eye Screw is designed for lifting, pulling, and securing applications under the ASME/ANSI standard system. It provides a convenient attachment point for equipment maintenance, component handling, and fixture positioning. The eye head connects to rigging hardware, while the threaded end engages with a prepared tapped hole.
Type A/B options support selection for different application conditions and are useful for projects requiring inch-standard procurement, assembly, or spare-part replacement. Actual use should be verified against lifting angle, load direction, and base material strength.
Carbon steel, stainless steel, or coated versions can be supplied to meet durability requirements in general industrial, outdoor handling, or maintenance environments.
