National Marker N220863 Steel Screw Hook 0.25x4.25 in

Product Description

The NATIONAL MARKER N220863 is a steel screw hook designed for medium-weight to heavy-weight hanging applications. Featuring lag screw threads, it drives securely into wood framing, joists, or structural lumber without a pilot anchor. The hook profile is suited for suspending planters, signage, clotheslines, and similar loads. At 0.25 inches in diameter and 4.25 inches in length, this hook provides a sturdy engagement depth appropriate for solid wood substrates. Installers in light commercial and residential settings rely on this style of fastener where a threaded, removable hang point is preferred over a fixed bracket or anchor.

This screw hook is appropriate for both indoor and outdoor hanging tasks where a threaded steel fastener is specified. Common applications include retail signage mounting, facility maintenance hang points, and general-purpose overhead suspension in warehouses, workshops, or residential spaces. The lag screw thread pattern allows direct installation into wood without requiring a nut or additional hardware. Each hook is sold individually.

Key Features

• Lag screw thread pattern for direct wood installation with no additional hardware
• 0.25-inch diameter shank provides solid purchase in wood framing and lumber
• 4.25-inch overall length delivers sufficient thread engagement depth
• Steel construction for durability under medium to heavy hanging loads
• Suitable for planters, signs, clotheslines, and general suspension tasks

Compatibility

Designed as a general-purpose lag-thread screw hook for direct installation into solid wood substrates in residential and light commercial applications.

Installation Notes

Installation is performed by maintenance technicians or general tradespeople using standard hand tools. Pre-drilling a pilot hole slightly smaller than the shank diameter is recommended to prevent wood splitting, particularly in hardwood or engineered lumber. Verify the substrate material and load rating are appropriate before hanging. Do not overtighten, as excessive torque can strip the thread engagement in the wood.
