National Marker N221572 Stainless Steel Eye Bolt 1/4x2

Product Description

The NATIONAL MARKER N221572 is a stainless steel eye bolt with a machine screw thread profile and an assembled hex nut, designed for secure fastening and lifting or rigging anchor applications. Measuring 1/4 inch in diameter by 2 inches in length, this eye bolt is manufactured from stainless steel for corrosion resistance in demanding environments. It is part of the 2161BC catalog series and is sold individually. Licensed trades including riggers, millwrights, and general contractors commonly specify stainless eye bolts where exposure to moisture, chemicals, or outdoor conditions would compromise a standard zinc or steel fastener.

This eye bolt is suited for residential and commercial installations where a corrosion-resistant threaded anchor point is required. Typical applications include cable management, equipment tie-down, overhead anchor points, marine environments, and outdoor structural work. The hex nut comes pre-assembled, reducing hardware prep time on the job. At 1/4 inch thread diameter and 2 inches of shank length, this fastener fits a wide range of standard panel thicknesses and framing members commonly encountered in trade work.

Key Features

• Stainless steel construction resists corrosion in wet, outdoor, and chemically exposed environments

Compatibility

Designed as an OEM-style replacement or direct-install stainless steel eye bolt for standard 1/4 inch threaded applications in trade and industrial fastening systems.

Installation Notes

Installation is performed by the appropriate licensed trade or qualified installer based on the application and load requirements. Always ensure the mounting substrate can support the intended load before installing any eye bolt used as a lifting or anchor point. Torque the hex nut to the substrate using standard hand tools; consult applicable load ratings and local codes before use in overhead or safety-critical rigging. Never exceed the rated working load limit of the fastener or the substrate material.
