Simpson Strong-Tie Fastener Checklist: 8 Steps Before You Install Connectors, Brackets, or Bolts

Who This Checklist Is For

If you're about to order or install Simpson Strong-Tie products for a project that can't afford a do-over, this is for you. It's short and practical, not a full engineering course. I've worked at a building supply company for 13 years, mostly helping contractors find the right Simpson Strong-Tie connector, bolt, screw, and anchor when the job is already moving fast. This is the checklist I run through when someone calls with an urgent framing or fastener problem and doesn't have time to ask the wrong question twice.

One honest limitation before we start: I'm not a structural engineer. This guide helps you avoid the obvious traps and ask better questions, but it's no substitute for stamped drawings or a licensed professional's review. If your project needs an engineered connection, get one.

1. Start With the Connection, Not Just the Product

When someone asks me for a Simpson Strong-Tie bracket, the first thing I ask is what the bracket has to do. A post-to-concrete connection and a beam-to-post connection might look similar in photos, but their load paths are different. Describe the joint in plain language first: post to slab, beam to post, rafter to wall, shelf to stud.

That one sentence saves more time than any product selector. If the crew is waiting, the fastest answer comes from knowing where the load starts and where it needs to end.

2. Separate Structural Connectors From Decorative Hardware

This is the step people skip. Simpson Strong-Tie decorative hardware is a real category, and some of it genuinely looks like structural material. You see clean lines, powder coat, thicker steel, and it's easy to think it must be an upgrade. But a pretty finish does not change load ratings.

Decorative hardware can have weight limits and application notes, but it may not carry the same allowable-load listings as the engineered structural connector line. I've watched someone try to use a decorative shelf bracket for a stair connection because it looked like the correct pattern. It looked impressive. It was still the wrong product for that job.

The fix is to compare part numbers, not appearances. If the job is load-bearing, choose a product with a published load table and an installation sheet you can check.

3. Check Shelf Bracket Weight Capacity Before You Mount Anything

For an actual shelf, the relevant number is not how strong the bracket feels in your hand. It is the published shelf bracket weight capacity for that exact part and fastener schedule.

Simpson Strong-Tie gives load information for the products that are intended to carry load. That rating assumes you follow the spacing and mounting requirements. A bracket rated for 250 pounds into solid framing may not hold anywhere near that amount if you attach it to hollow wall material with short screws. The bracket may be fine while the wall fails.

When I compare two brackets side by side, I start with their rated capacities. One bracket can look thicker and still have a lower rated capacity because of fewer screw holes or a different steel spec. The visuals tell you almost nothing.

4. Use the Specified Simpson Strong-Tie Bolt or Fastener

Many emergency calls happen after a connector is mounted with the wrong fastener. The hanger is correct, the hole pattern is correct, but the fasteners came from a mixed box in the back of a truck. That's where the job gets into trouble.

If a connector requires a specific Simpson Strong-Tie bolt, screw, or anchor, the installation instructions will list it. The drawing may call for a machine bolt with nut and washer, or it may call for a structural screw. If it says a specific diameter and length, don't substitute just because the threads look close. Bolt grade, length, thread engagement, and head style all matter.

I keep saying Simpson Strong-Tie bolt because so many people describe fasteners only by diameter. The real question is whether the fastener matches the exact specification on the connector's label. If it doesn't, the connection is not the connection you think it is.

5. Make Sure the Cordless Drill Is Charged Before It Matters

This sounds too simple to be a checklist item, but it costs real time on real jobs. You can have the right connector and the right fastener, and still lose an hour because the drill battery is dead.

If you're wondering how to charge cordless drill batteries so they last through an install, the practical answer is routine. Use the manufacturer charger. Keep batteries at room temperature when you can. Put them on the charger after a job, not right before the next one starts. A cold battery can read low, and an old battery can lie about its charge level.

Before you walk out to the beam or the shelf bracket, run the driver once with the bit seated. It's a five-second test that prevents a thirty-minute delay.

6. Give the Roof Tools the Same Five-Minute Check

Here's a topic that sounds unrelated but isn't: roofing nail gun parts. If you're working on roof sheathing, shingle work, or any connection that calls for pneumatically driven nails, the nailer becomes part of installation quality. A gun that under-drives nails can compromise a connection even when the connector itself is perfect.

Worn bumpers, cracked driver blades, and tired seals cause fasteners to sit proud or feed poorly. I've seen crews blame a bracket when the real problem was a nail gun that needed a small rebuild kit. Keeping a few spare roofing nail gun parts in the trailer beats paying a crew to stand around while the tool decides to behave.

If the gun won't seat nails flush, stop. Don't adjust the compressor pressure and hope the problem goes away. Replace the worn part first, then test on scrap material.

7. Read the Printed Instructions Even If You Know the Product

There is no reason to install a Simpson Strong-Tie connector from memory. The instructions are printed on the packaging and available online for most products. They show orientation, fastener schedules, and minimum edge distances.

I learned that after ignoring it once. I had installed the same product the month before, so I skipped the sheet and put the connector in backward. It took about ten minutes to realize why the beam wasn't seating right. The instructions were in the box the whole time.

Crews that rarely have callbacks still check the sheet. They don't do it because they're new. They do it because connector orientation changes and tiny details matter.

8. Do a Final Physical Check Before Loading the Connection

After the screws are tight or the bolts are torqued, check the connection with your hand, not just your eyes. Run your fingers over screw heads to feel for proud heads. Look at the washer position on a bolt. Wiggle a shelf bracket before you stack anything on it. That wiggle tells you more than the label does.

If a connector is out of line, loosen the fasteners and adjust it before the load goes on. If a bolt doesn't seem to have enough thread engagement, don't add a washer to fix it. Verify the right bolt was used and change it if necessary.

When the Checklist Says Stop

If something doesn't line up, don't hope it settles. If the product is decorative but the application is structural, get the right connector. If the Simpson Strong-Tie fastener called out in the instructions doesn't match what's in your hand, go back before you make the installation worse.

There's something satisfying about a connection you never have to revisit. Not because you got lucky, but because you checked the capacity, used the specified hardware, and made sure the tools were ready before the work started. That's the point of this checklist.

Product examples in this article refer to Simpson Strong-Tie products as identified in their current catalogs and installation literature. Always verify the specific ratings, fasteners, and orientation requirements for the exact model you plan to use.
