8-pack fence post anchors for 3.5-inch timber

This set supplies eight steel ground spikes designed to secure 3.5 x 3.5 inch square posts. Each anchor stands 24 inches tall with an 18-inch nail section driven into the ground. The powder-coated finish protects the steel from soil moisture and rain while shielding the timber from rot. Included hardware provides 16 screws and 16 anti-loose nuts for immediate installation.

Suits deck, mailbox and garden railing projects

Builders erecting fences, deck rails or mailbox posts on level ground will find the 3.5-inch inner width a direct fit for standard lumber. The kit includes all fasteners so no extra trips to the hardware store are needed. Installers who require adjustable height, angled mounting or a larger post size should look at alternative anchor styles because these spikes are fixed at 24 inches and accept only 3.5-inch square timber.

Handles eight posts with 18 inches of ground

Eight anchors give enough units for a typical residential fence line or deck perimeter. The 18-inch nail depth resists uplift in firm soil, and the 1.7 mm steel thickness resists bending during driving. In loose sand, heavy clay or rocky terrain the holding power will be lower and supplementary bracing or concrete may be necessary.

Questions about this item

What size square timber do I need to fit the 3.5-inch inner width of these anchors?

The anchors are sized for 3.5 x 3.5 inch square timber, which matches standard nominal 4x4 lumber dimensions.

Can I use these 24-inch spikes with my existing 4x4 posts that are already set in concrete footings?

These ground spikes are designed for direct soil installation with an 18-inch nail length; they are not intended for mounting onto existing concrete footings.

How do I confirm the anchors are properly secured after driving them in and attaching the timber?

Check that the 16 screws and 16 anti-loose nuts are fully tightened through the fixing plates, and verify the post sits flush inside the 3.5-inch inner width without movement.
