Upgrade your outdoor builds with this 8-pack of rugged, black powder-coated steel ground spikes. Engineered for standard 4x4 lumber (fits 3.6x3.6 in. actual), these anchors deliver rock-solid stability without messy concrete or digging. Built from heavy-duty carbon steel with a corrosion-resistant finish, these 22-inch anchors withstand rain, snow, and sun year after year. The extended length ensures deep soil penetration for superior hold. Simply hammer the spike into the earth with a wood block, insert your post, and secure. By elevating wood above damp soil, these anchors help prevent rot, fungal decay, and insect damage. Perfect for fences, mailboxes, deck railings, pergolas, and gazebos. Ideal for DIYers and pros seeking long-lasting durability.
