National Marker N221663 Stainless Steel Eye Bolt 3/8x6

Product Description

The NATIONAL MARKER N221663 is a stainless steel eye bolt measuring 3/8 inch diameter by 6 inches in length, supplied with an assembled hex nut. It features machine screw threads for secure fastening and is manufactured from stainless steel for corrosion resistance. This hardware is suited for rigging, lifting, anchoring, and tie-down applications where exposure to moisture or corrosive environments is a concern. Licensed contractors, maintenance technicians, and trade professionals install these fasteners across commercial and industrial job sites.

This eye bolt is well suited for interior and exterior applications requiring a dependable anchor point. Typical uses include securing cable runs, supporting pipe hangers, mounting pulleys, or creating anchor points on structural members. The stainless steel construction makes it appropriate for humid or outdoor environments where standard carbon steel hardware would corrode prematurely. It is sold individually and arrives assembled with the hex nut ready for installation.

Installation Notes

Eye bolts of this type are installed by trade professionals and maintenance technicians using standard hand tools including wrenches sized to the hex nut. Ensure the mating structure or anchor point is rated for the intended load before installation. Always orient the eye in line with the direction of pull to prevent bending or side-loading the shank. Follow applicable local building codes and rigging standards when using eye bolts in lifting or overhead load applications.
