National Mfg N220-640 Hitching Ring Eye Bolt 5/16 X 3-1/4 Zinc

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N220-640 is a zinc-plated hitching ring with attached eye bolt, built for medium-weight animal tie-down and general farm or home fastening applications. The assembly combines a welded wire ring with a lag-thread eye bolt for a secure, ready-to-install connection point. The ring measures 2 inches inside diameter, formed from 0 wire (.300 inch diameter), welded construction. The eye bolt is 5/16 inch - 18 thread by 3-1/4 inches in length with a lag thread end for direct wood mounting. Safe working load is rated at 160 pounds. Sold in a package of 10 units.

This hitching ring is suited for residential, farm, and ranch settings where a reliable animal tie-down point is needed. Common applications include fence posts, barn walls, stall framing, and similar wood structures where a lag-thread fastener is appropriate. The zinc finish provides basic corrosion resistance for outdoor and semi-exposed environments. The included eye bolt eliminates the need to source hardware separately, making this a complete tie-down anchor solution for livestock handlers, property owners, and farm maintenance crews.

Installation Notes

Installation is performed by threading the lag bolt end directly into a structurally sound wood post, beam, or framing member — no nut or through-bolt is required for lag-thread mounting. Pre-drilling a pilot hole appropriate to the lag thread diameter is recommended to prevent wood splitting and ensure full thread engagement. Verify the mounting substrate can sustain the rated working load before use. Inspect the ring and eye bolt connection periodically for wear, deformation, or corrosion.
