National Mfg N221-648 Ss Eye Bolt 3/8x4 in 160LB 10pk

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N221-648 is a stainless steel eye bolt with hex nut, sized at 3/8 inch diameter by 4 inches in length and rated to hold up to 160 pounds. Each bolt features a closed-loop eye designed for attaching cables, ropes, hooks, or rigging hardware to a fixed surface. Stainless steel construction provides corrosion resistance in wet, outdoor, or marine-adjacent environments where carbon steel fasteners would degrade. Each unit ships with a matching hex nut for secure through-bolt or anchored installation. This SKU is sold in a box of 10 units.

This eye bolt is suited for light rigging, hanging, tie-down, and anchoring applications in residential and light commercial settings. Typical uses include securing rope lines, hanging equipment, or anchoring load-bearing fixtures to wood framing, structural members, or similar substrates. Installation is performed by general contractors, maintenance technicians, or experienced DIYers. The 160-pound load rating makes this appropriate for moderate static loads rather than dynamic or overhead lifting applications without further engineering review.

Key Features

• 3/8 inch diameter by 4 inch length for deep engagement in structural substrates
• Stainless steel construction resists corrosion in outdoor and high-moisture environments
• 160-pound load capacity for moderate static anchoring and tie-down applications
• Includes matching hex nut for secure, flush installation
• Sold in a pack of 10 units for multi-point installations or stock replenishment

Compatibility

Designed as a standard 3/8 inch eye bolt for use in wood, structural framing, and similar substrates where a threaded fastener with an attachment loop is required.

Installation Notes

Install by drilling a pilot hole appropriate for a 3/8 inch bolt thread before driving into wood or soft substrates to prevent splitting. Secure the hex nut firmly against the mounting surface to prevent loosening under load. Always verify that the substrate and mounting point are rated to support the intended load before use. This fastener is intended for static load applications and should not be used as a certified lifting point without a load engineer review.
