“Your Simpson Strong-Tie post bracket failed.”
That message arrived in June 2022, and it made me angry before it made me smart. A corner post on a covered porch had shifted about half an inch at its base during a storm. The beam above moved with it. The homeowner sent a photo of the galvanized post bracket still attached to the concrete pier and assumed the steel had given way.
The steel hadn’t given way. The concrete anchor was still tight. What let go were two stainless screws from my own trailer—leftovers from another job that looked close enough to the specified structural screws. It was my mistake, not the bracket’s. The repair cost $2,850. It also cost three weeks of schedule and a few references that I used to take for granted.
The Surface Problem: We Blame the Visible Steel
When a connection fails, the visible hardware gets photographed, and the bracket is usually in the frame. That makes it the natural suspect.
I documented eleven connection callbacks between 2017 and Q3 2024. In most of those, the steel did not fail. The connection around the steel failed. The fastener schedule was wrong, the anchor was wrong, the model wasn’t actually specified, or the rating had been erased with a grinder.
That was hard to accept because I like neat explanations. The frustrating truth is that a structural connector is not a standalone part. A bracket is only one step in a load path. If the step before it or after it is wrong, the bracket doesn’t save you.
What Actually Causes Post-Bracket Problems
1. Ordering a Shape, Not a Specification
The phrase “Simpson Strong-Tie post brackets” is not a specification. It is a category. A post bracket can be a post base, a post cap, or a connector for a specific load direction. Those models are not interchangeable, even when they look similar.
The same is true for the “Simpson Strong-Tie angle bracket.” A structural angle bracket is only defined by its model number and load table. Gauge, coating, hole pattern, and allowable load all change with the model. If the order says “angle bracket” but no model number appears, you have ordered a piece of bent metal, not an engineered connector.
2. Substituting Fasteners Because They Look Right
On the porch job, I didn’t choose a cheaper fastener. I chose one I already had in the trailer because the head size looked the same. A published connector load is tied to the connector and its listed fasteners. Change the screw, and the tested value no longer applies.
Here’s the thing I tell new crew members: the words “structural screw” matter. The required screw type isn’t just a suggestion; it’s part of the code-approved assembly. If the specified screw is not in the box, you don’t have the rated connection.
3. Using the Same Words but Meaning Different Things
On another job, I called a supplier and read my material list. For one item, I said “post brackets.” They heard “the usual post brackets for a deck.” I meant “the galvanized connectors marked on the approved structural drawings.”
We were using the same words and meaning different things. We caught the mismatch only when I compared the delivered model numbers to the drawing schedule. That conversation added a two-week delay and a restocking fee. It was not a metal failure. It was a language failure.
4. Cutting a Connector to Make It Fit
A few years ago, a crew lead held up a galvanized connector and asked, “Does an angle grinder cut metal? Because I can trim this corner so it fits flat.” Yes, an angle grinder will cut metal. That’s exactly why it does not belong on a structural connector.
Cutting, grinding, notching, or bending rated hardware changes the shape the load value is based on. The catalog rating disappears. If a Simpson Strong-Tie angle bracket doesn’t fit, fix the layout or choose a connector that fits the layout. Don’t modify the connector to make it “work.”
The Real Cost Is Not the Price of the Bracket
The bracket that triggered my June 2022 failure was not expensive. The rework, the engineer’s letter, the replacement material, and the lost schedule were expensive. That is why I now compare total connection costs, not bracket prices.
When I ask for a quote, I also ask what’s not included. A supplier who lists the anchor, the fasteners, and the installation notes upfront is not trying to make the quote look worse. They’re trying to make the job safer. A quote that only says “post brackets — $X” is not transparent. It’s an invitation to a callback.
What I Check Now Before I Order and Before Concrete Is Poured
As of January 2025, I no longer approve a connector order without opening the current load table. For Simpson Strong-Tie products, I use the current Wood Construction Connectors catalog or the product portal at strongtie.com. If the connector goes into concrete, I check the applicable ICC-ES report at icc-es.org for the anchor size, embedment, edge distance, and hole diameter.
On the jobsite, I do a ten-minute review before concrete is poured. The question isn’t “Is the bracket tight?” It’s “What is the load path from this beam down to the foundation, and which published rating covers it?” If we can’t answer that, the connector is decorative until an engineer or the manufacturer says otherwise.
A sharp drill bit helps, too. I keep a CMAM3211 titanium drill bit set in the trailer for clean pilot holes in metal. But a clean hole only matters if it is the size and depth the anchor installation instructions require. The bit model is not the specification. The anchor’s report is.
The bracket in the photo wasn’t the problem. The process was. I fixed the process, and I stopped blaming steel.
