Heavy-Duty Post Bases for 4x4 Columns

This pack contains ten post bases designed to fit standard 4x4 wood posts with an actual 3.5x3.5 inch cross-section. Each bracket has an internal dimension of 3.6x3.6 inches and is made from 1.6mm thick carbon steel. The powder-coated finish provides corrosion resistance for outdoor deck, porch and handrail projects.

Powder-Coated Steel Resists Rust

The carbon steel construction uses a spray paint coating process that protects against moisture and oxidation. At 0.06 inches thick, the material resists bending under load. The kit weighs 4.1 kg in total and each piece measures 153x153x62 mm. No moving parts or electronics are present, so thermal output and noise are not applicable.

Pre-Drilled Holes and Fasteners Included

Installation uses the pre-drilled screw holes with the supplied 130 self-tapping screws and 44 yellowfish expansion sleeves. The hardware allows direct mounting to concrete or wood surfaces without separate parts sourcing. The 7.87 inch width specification applies to the overall bracket footprint.

Questions about this item

How do I install the post bases using the 130 self-tapping screws and 44 yellowfish expansion sleeves?

Drill pilot holes in the concrete or wood surface, insert the 44 yellowfish expansion sleeves, then drive the 130 self-tapping screws through the bracket holes into the sleeves; the step often missed is pre-drilling the correct sleeve diameter so the anchors grip fully.

What maintenance or replacement will the carbon steel brackets with 1.6mm thickness and powder-coated finish need over time?

Inspect the powder-coated surface annually for chips or scratches; touch up any exposed carbon steel with rust-inhibiting paint to prevent corrosion, and retighten the self-tapping screws if seasonal wood movement loosens the connection.

At what load or condition does the 3.6in internal dimension and 1.6mm steel thickness show its limit under sustained use?

The 3.6in pocket fits nominal 4x4 posts (actual 3.5in), so prolonged heavy vertical loads or lateral sway can eventually bend the 1.6mm steel or crush the wood fibres at the bracket-to-post interface.
