"Just buy the good stuff."
I'm a procurement manager at a mid-size commercial general contractor — about 85 people. For the past 7 years, I've managed our structural hardware budget (roughly $240,000 annually), negotiated with over 15 vendors, and logged every order in our cost tracking system. And "just buy the good stuff" is fine advice until you're the one making 400 purchasing decisions a year and the difference between "good enough" and "overkill" is your quarterly budget.
Here's what I've learned: there is no single right answer. You came here probably trying to figure out whether a specific project needs engineered Simpson Strong-Tie connectors or whether standard screws will do. That depends entirely on what the connection is actually doing. So let me break this down the way I actually think about it — three scenarios, each with a different TCO calculation, and a test to figure out which one you're in.
The Three Scenarios That Make This Decision Manageable
I'll spoil the ending upfront: almost everything comes down to one question — is this connection load-bearing? If yes, there's no discussion. If no, there's real optimization space.
But the errors I see most often happen in the gray zone. Here's the breakdown I use:
- Scenario A: Structural and/or code-governed connections. The connector carries load, or the code explicitly specifies hardware.
- Scenario B: Non-structural but high-consequence connections. No load path, but failure means rework or callbacks.
- Scenario C: General-purpose, shop, or temporary connections. Failure is annoying at worst, not expensive.
Misplacing yourself between these scenarios is where money gets burned. Let me take them one at a time.
Scenario A: When the Connector Is Carrying Load
No negotiation. No optimization. You install exactly what the spec calls for. If your structural drawings say Simpson Strong-Tie T bracket, and you're thinking about substituting something cheaper because "it looks the same" — stop. That's not a decision your inspection will let you make anyway. The check comes later. The cost comes later too.
Let me give you a real example. We use Simpson Strong-Tie T brackets for beam-to-post connections. Our vendor quoted us around $14-$22 per bracket depending on gauge, versus generic alternatives at roughly $6-$8 for something that looked visually identical. For an 18-bracket job, that's a $280 difference.
Looks like free money. It's not. Simpson's T brackets come with ESR reports (ICC Evaluation Service), meet specific ASTM test protocols, and have engineering load values behind them. When the project gets inspected — and it will — that paperwork is what you need. If you used a non-ESR substitute, you're removing and reinstalling at your own cost. We estimated a single failed structural connection at framing stage costs about $3,000 in labor, removal, reinstatement, and reinspection. That's what you're risking to save $280. Actually, closer to $400 with the volume discount we'd lose.
That's not cost savings. That's gambling.
Same logic applies to structural bolts. When it's load-bearing, Simpson Strong-Tie bolt systems (SDS, Strong-Drive, and their anchor lines) are manufactured and tested to specific load values. A generic bolt of similar diameter might look equivalent, but it doesn't carry the same verification data. In structural applications, you can't legally substitute something without independent validation.
This catches people off guard — especially those coming from other industries. They think "a bolt is a bolt." It isn't. Thread geometry, material grade, heat treatment — all of that drives load capacity. And when your inspector asks for documentation, the generic bolt gives you a label. Simpson gives you a file.
Scenario B: Non-Structural But High-Consequence
This is where the real optimization happens — and where understanding your hardware actually matters.
Let's get one thing straight first, because if we don't align on this, nothing else follows: what is a screw, really? It's a fastener with a helical thread that's driven into a material by rotation. It creates holding power through two mechanisms — mechanical engagement between the thread and the base material, and clamping force from the screw head against the material being fastened. That applies to everything. But the difference in structural contexts is whether the thread cuts, forms, or displaces material — and how that affects load capacity under tension and shear.
Self-drilling screws are the interesting middle ground. They have a drill point at the tip, so they create their own hole while simultaneously tapping threads. For thin-gauge metal, light steel framing, or wood-to-metal connections, these are dramatically more efficient than pre-drilling and driving a separate fastener.
From a cost standpoint: I've calculated that using self-drilling screws on a typical metal framing project saves roughly 30% in labor hours. Not material cost — labor. And labor is where most project budgets actually live.
But here's the nuance most people miss. The drill point and the threads on a self-drilling screw are not the same thing. If you're drilling through thicker material, the point can overheat and dull. I've watched crews try to drive a 16-gauge screw through a thicker steel plate and end up with stripped heads and wasted hardware because the point wasn't rated for it. That's not a screw failure — that's a selection failure. And you won't catch it by looking at the screw. You catch it by reading the load table.
One more thing that seems minor but has cost me real money: if you're working with NPT ports and you need to know what drill bit for 1/8 NPT tap — that's 21/64", or 0.328". If I remember correctly, it's the same for both tapered and straight pipe threads at that size, though I might be misremembering the straight-thread case. Either way, it's a hard spec. Don't guess. I've seen someone snap a tap in a hole because they used a 5/16" bit "close enough." That's a $85 tap-and-extractor kit plus an hour of lost time. The invoice never shows this. The schedule does.
Back to Scenario B. Your decision rule here is: if this connection failing means more than $500 to fix — or causes someone embarrassment — use a brand with documentation and match the fastener to the substrate. Simpson Strong-Tie is genuinely good here because their technical literature tells you exactly which screw for which base material. You don't have to trust my experience. You just have to read the table.
Scenario C: General-Purpose, Shop, and Temporary
Here's the counterintuitive part. And it's the part most procurement managers won't say out loud.
For shop jigs, temporary bracing, construction aids on non-critical projects — you don't need engineered connectors. Standard screws are fine. Paying the premium is a waste of money.
I wrestled with this one. I went back and forth between specifying Simpson hardware for everything and splitting the spec for two weeks on our last big job. On paper, the single-spec approach meant fewer ordering errors and easier inventory. But my gut said we were paying a premium for things that didn't need it. We ended up with a two-tier standard — engineered hardware for structural, standard screws for non-structural — and saved about 22% on fasteners. No failures. No callbacks.
But here's the counterintuitive catch: cheap doesn't mean cheapest. The genuinely bad scenario is when the thread tolerances are off, the head is soft, and the fastener strips under load. That's rare, but when it happens, it costs you every time you touch that joint for the next three years.
So even in Scenario C, there's a quality floor. My rule of thumb: any standard screw from a reputable brand is fine for anything that won't be under sustained load. But if you've had to redrive a certain fastener twice, find a different supplier. Don't keep saving pennies on something that's costing you hours.
How to Figure Out Which Scenario You're In
Answer these three questions in order:
- Is this connection carrying load? If yes, or if you're not sure — you're in Scenario A. There's no cost optimization here. Buy the engineered product with the documentation, and use the exact specified model.
- If no, will failure cost more than $500 to fix? If yes, you're in Scenario B. Use a brand with load tables and match the fastener to your substrate and loading condition. Read the literature.
- If still no, you're in Scenario C. Standard screws are fine. Don't overspec. But don't cut corners on thread quality — if a screw strips out of a jig or temporary brace, you're spending more time fixing it than you saved on the purchase.
One closing thought. If you're wondering whether something will be inspected, you already know the answer. It will be. Plan accordingly.
Last thing, and I want to be honest about this: the pricing I used here reflects early 2025. Steel pricing has been volatile since 2020, and I've seen structural hardware costs swing 15% in six months. Verify current rates with your supplier before you budget against these numbers.
But the framework itself hasn't changed. Match the hardware to the consequence. Calculate TCO, not unit price. Spend where it matters, and don't spend where it doesn't.
