Simpson Strong Tie BC4Z-R 4x4 Post Cap Base Z-max

Product Description

The SIMPSON STRONG TIE BC4Z-R is an 18-gauge galvanized steel post cap and base connector designed to create a secure structural connection between 4x4 posts and beams. Sold in a package of 20 units, it is intended for residential and light commercial framing applications where post-to-beam load transfer is required. The BC4Z-R eliminates end-grain nailing, which significantly reduces the risk of wood splitting at the post top. Installation requires 12 nails total across both bearing surfaces. Licensed contractors, framers, and deck builders install this hardware as part of code-compliant structural assemblies.

The BC4Z-R is suited for deck construction, pergolas, outdoor pavilions, and other wood-framed structures where a post cap or base connection is needed at 4x4 nominal lumber. The Z-Max coating provides enhanced corrosion resistance compared to standard G90 galvanizing, making it appropriate for treated lumber applications and exterior environments subject to moisture exposure. It is packaged in quantities of 20, supporting both single-job and multi-post installations efficiently.
