N221-309 EYE BOLT W/NUT 1/2X4IN ZINC

Overview

The National Hardware Eye Bolt with Nut (N221-309) is designed for fastening, lifting, and tie-down applications in home, farm, builder, and industrial environments.

Technical Features

• Zinc-plated steel construction — provides corrosion resistance, extending the service life of the fastener in both indoor and outdoor environments.
• 300 lb working load limit — establishes a defined safe-use threshold for lifting, hanging, and tie-down tasks, supporting load planning on the job site.
• 1/2 in. thread size with 4 in. overall length — delivers substantial thread engagement depth for secure anchoring into structural substrates.
• 2.14 in. length under eye — provides adequate shank length for installation through materials of varying thickness.
• 1 in. inside eye diameter — accommodates standard hooks, carabiners, rope, and chain connections without modification.
• Nut included — allows for immediate installation without sourcing a separate matching fastener, reducing setup time.
• Bagged, single-piece packaging — keeps the fastener and nut together for straightforward handling and storage on site.

Applications

• Residential, farm, and light industrial tie-down and anchoring applications
• Attachment point for rope, wire, cable, or chain in overhead or lateral rigging setups
• Outdoor installations where zinc-plated corrosion resistance is required
• Builder and contractor use requiring a rated, threaded anchor point in wood or similar structural materials
