National Marker N221101 Zinc Eye Bolt with Hex Nut

Product Description

The NATIONAL MARKER N221101 is a zinc-plated steel wire eye bolt with an assembled hex nut, built for reliable fastening in both home and industrial settings. Sized at 1/4 inch diameter by 2-1/2 inches in length, it features machine screw threads that mate cleanly with the included hex nut. The zinc finish provides corrosion resistance, making this eye bolt suitable for interior and exterior use. Licensed tradespeople, maintenance crews, and general contractors reach for this hardware when hanging cable runs, securing equipment, or anchoring rope and chain to structural surfaces.

This eye bolt fits into a wide range of light-duty to medium-duty fastening applications. Its compact 1/4 inch by 2-1/2 inch profile works in framing members, wood beams, metal panels, and other substrates where a threaded eye anchor is needed. The assembled hex nut allows for immediate installation without sourcing additional hardware. Suitable for both indoor and outdoor environments, it is a standard choice wherever a secure loop anchor point is required on the job site or in a facility.

Installation Notes

Installation is typically performed by maintenance technicians, electricians, or general tradespeople using standard hand tools. Always pre-drill a pilot hole sized to the bolt diameter when threading into wood or structural members to avoid splitting. Ensure the mounting substrate can bear the intended load before finalizing installation. Tighten the hex nut securely against the surface, but do not over-torque, as steel wire eye bolts can distort the eye loop under excessive force.
