National Mfg N221-218 Zinc Eye Bolt 5/16x3-1/4 in 90 Lb

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N221-218 is a zinc-plated eye bolt measuring 5/16 inches in diameter by 3-1/4 inches in length, rated for a 90-pound load capacity. Eye bolts of this type are used to create a fixed anchor point for light-duty rigging, hanging, or cable routing applications. The zinc plating provides basic corrosion resistance for indoor and sheltered outdoor use. This fastener is sold in bulk quantity and is appropriate for contractors, maintenance technicians, and tradespeople who need a reliable, standard-thread anchor point in wood or similar substrates.

This eye bolt is suited for light-duty load applications in residential and light commercial settings. Typical uses include suspending conduit hangers, securing rope or cable runs, anchoring small equipment supports, and similar low-load fastening tasks. It is commonly installed by electricians, HVAC technicians, and general maintenance crews during rough-in or finish work where a threaded eye anchor is required.

Installation Notes

Installation is typically performed by hand with the aid of a screwdriver, rod, or appropriate driver inserted through the eye loop for torque. Always verify that the substrate material can support the stated load before installation. Do not exceed the 90-pound rated load capacity. Power down or de-energize any nearby systems before drilling pilot holes in finished structures.
