This eye bolt is well suited for use in plumbing, HVAC, electrical, and general construction applications where a threaded anchor point is needed. Its corrosion-resistant stainless steel construction makes it appropriate for outdoor installations, marine-adjacent environments, and areas subject to moisture or chemical exposure. The assembled hex nut allows for immediate installation without additional hardware sourcing.
Designed as an OEM-style replacement or standard component for general fastening, rigging, and suspension applications requiring a 0.25 inch machine-threaded eye bolt with hex nut.
Installation is typically performed by general contractors, electricians, plumbers, or HVAC technicians depending on the application. Ensure the mounting substrate is rated for the intended load before installation. Use appropriate hand tools and verify thread engagement is complete before applying load. Follow applicable local building codes and load-rating guidelines for overhead or structural fastening applications.
