National Marker N221630 Stainless Steel Eye Bolt 5/16x5 In.

Product Description

The NATIONAL MARKER N221630 is a stainless steel eye bolt designed for lifting, rigging, and anchoring applications across industrial, commercial, and marine environments. Measuring 5/16 inch in diameter and 5 inches in length, it features machine screw threads and comes assembled with a hex nut for immediate installation. The stainless steel construction provides corrosion resistance, making this fastener suitable for outdoor, wet, or chemically exposed settings. Licensed contractors, riggers, and maintenance professionals reach for this type of hardware when a reliable, corrosion-resistant anchor point is required.

This eye bolt is appropriate for use in construction, facility maintenance, marine rigging, and similar trade applications where a threaded, load-bearing anchor point must resist rust and environmental exposure. The assembled hex nut simplifies installation and helps ensure consistent seating against the mounting surface. It is sold individually (UOM: Each) with a minimum order quantity of 10 units, making it practical for jobsite stocking.

Installation Notes

Installation is typically performed by maintenance technicians, riggers, or general contractors using standard hand tools. Before installing in any load-bearing application, verify that the mounting substrate is rated for the intended load and that the hex nut is fully tightened against the bearing surface. Always follow applicable ASME, OSHA, and local rigging codes when using eye bolts in lifting or overhead anchoring applications. Do not use a damaged or deformed eye bolt in any load-bearing capacity.
