Fasteners and Hardware โ FAQ
What size anchor do I need for my garage?
For securing sheds or lightweight structures, 18-inch anchors suffice. Heavy equipment and carports require 24-30 inch models for adequate hold. Always check local building codes for specific requirements.
How deep should I install garage anchors?
Install anchors until the spiral is fully buried and the eyelet sits flush with ground level. In frost-prone areas, extend 6 inches below the frost line to prevent heaving. Most applications require 18-24 inches of penetration.
Can I install screw anchors in concrete?
No, screw anchors require soil to function. For concrete garage floors, use wedge anchors or epoxy-mounted systems instead. Some anchors work in asphalt with pre-drilled pilot holes.
How many anchors do I need to secure a shed?
A standard 8x10 foot shed requires one anchor per corner (four total). Larger structures need anchors every 6-8 feet along the perimeter. High-wind zones may require additional anchoring points.
What's the typical weight capacity of garage anchors?
Quality 18-inch anchors hold 500-800 pounds in firm soil. 24-30 inch models exceed 1,200 pounds. Actual capacity depends on soil composition, moisture content, and installation depth. Always use a safety factor of 2:1.
How do I remove screw-in anchors?
Reverse installation using a pipe wrench or socket on the anchor head. For stubborn anchors, apply penetrating oil and use a cheater bar for leverage. Severely rusted anchors may require excavation and cutting.
