Gunnebo Swivel Hook vs. Durasteel Screw Hook: How to Choose the Right Lifting Hardware

There's No Universal Hook. Only the Right Hook for Your Application

There's no universal answer to 'which lifting hook should I use?' That sounds evasive, but it's the truth after you've spent years watching components come back from the field. I'm a quality and brand compliance manager for a rigging supplier. I review lifting hardware before it ships—roughly 200 unique items per year, give or take, depending on the quarter. The list includes hooks, shackles, swivels, screws, and replacement latch kits. In that time, I've developed one firm opinion: prevention beats repair. It's cheaper to get the spec right before the order than to explain a failure after the fact.

Asking which hook is best is a little like asking what are the best garden tool storage solutions? In one shed, a wall-mounted rail makes sense. In another, a lockable deck box is the only way to keep tools dry. Both are valid. The deciding factors are space, access, and what you're storing. Lifting hardware is no different. The deciding factors are load path, environment, and how often the hook is connected.

First, Define Your Scenario

In our Q1 2025 quality audit, we reviewed 470 returned components. One pattern stood out: most problems weren't manufacturing defects. They were selection errors. Hooks bent because someone sized by hook opening instead of Working Load Limit. Latches failed because they were used as load-bearing parts. Swivels bound up because the application had constant twisting and the swivel was never rated for it.

So this article won't give you one 'best' hook. Instead, I'll walk through three common scenarios and the choices that make sense in each. Then I'll tell you how to figure out which one mirrors your job.

Scenario 1: Frequent Connection and Changing Load Angle → Gunnebo Swivel Hook

If your crew connects and releases a hook multiple times per shift, and the load angle changes between picks, a fixed hook can force you to reposition the entire chain or sling. That's time lost, and it's also an invitation to misuse—people start attaching slings to the point where the hook opening is widest, which is not where you want contact.

A Gunnebo swivel hook solves that by letting the load find its own angle. The hook body rotates relative to the shank or eye. That means less twisting in the chain, less wear on the sling, and fewer awkward reconnects. What I mean is: the swivel is doing the alignment work instead of the operator.

But here's the nuance. A swivel hook is a mechanical assembly. It has more moving parts, which means more inspection points. If you don't keep the swivel clean and lubricated, it can become notchy, and a notchy swivel is worse than no swivel because it gives you a false sense of alignment. Put another way: choose a swivel for a high-cycle pick where repositioning is a real cost, not because it looks more advanced.

When I compared two identical picks side by side—one with a fixed hook, one with a Gunnebo swivel hook—the time difference was small on the first lift. By the tenth lift, the fixed hook required a sling reposition every time; the swivel hook did not. Seeing that pattern over a full shift made me realize why experienced riggers insist on swivels for repetitive work.

Scenario 2: Fixed Geometry and Simple Strength → Durasteel Screw Hook

Now the opposite situation. Your suspension point doesn't move. The load comes in the same orientation every time. The hook stays in place for weeks. Do you need a swivel? Not necessarily. A Durasteel screw hook—a forged hook with a threaded shank designed to screw into a load block, chain, or fixture—might be the cleaner choice.

A frequent assumption is that a swivel is always an upgrade. That's one I'd push back on. In a permanent installation, the extra bearing in a swivel is an extra wear point. It can trap grit, dry out, and eventually develop free play. A fixed screw hook has no bearing to fail. Its strength is in the simplicity of the load path. That's not a lower-end product; it's the right product for a defined geometry.

I once approved a Durasteel screw hook for a customer whose previous hook had a bent shank. They had been using a swivel hook in an application with zero rotation for two years. The swivel wasn't rotating anyway—it was just another component in the load path that could fail. When we swapped it for a fixed screw hook, the WLL was actually higher for the same thread size. That was the reverse validation I needed: I only fully understood the tradeoff after seeing a swivel that was never used as a swivel.

If you've ever worked through a ball valve catalog, you know the drill: you don't choose a valve by its handle length. You choose it by pressure, material, and end connection. Rigging is the same. A screw hook is selected by thread size, WLL, and orientation, not by how sturdy it looks.

In one project, the upside of choosing a lower-cost hook was $1,800 in savings. The risk was that the manufacturer couldn't provide a certified chemical composition for the forging. We asked for the cert. The order went to a supplier who could. The client still got the budget price, and we got the paperwork. Not ideal, but workable.

Scenario 3: Worn or Missing Latch → Gunnebo Hook Latch Kit

What if your existing hook is fine structurally, but the spring latch is broken? A full replacement isn't always necessary. A Gunnebo hook latch kit is designed to restore the hook's retention function using the same latch geometry as the original. That's a legitimate repair, provided the latch and the hook are compatible. Check the hook type, brand, and opening size before ordering—latches are not one-size-fits-all.

A customer once decided that a $35 latch kit wasn't necessary because the hook opening was barely larger than the sling. The wire they used to keep the sling in place looked fine on the ground. It failed on a lift, and the resulting rework cost more than the hook itself. The latch is not a load-bearing part. It's part of the safety system. The moment a latch is cracked, missing a spring, or doesn't snap back, the correct move is to stop using that hook until you replace the latch.

The upside of saving $35 was negligible. The risk was a dropped load. I kept asking myself: is that a trade anyone should approve? No.

Now, About That Garden Tool Question

What are the best garden tool storage solutions? It seems out of place in a lifting hardware article, but the thinking is identical. The best storage solution depends on whether the tools are used weekly or monthly, stored inside or outside, and whether they need to be secured. A Gunnebo swivel hook is the wall-mounted rack of rigging: great when you need frequent access. A Durasteel screw hook is the lockable cabinet: great when you need security in a permanent spot. And a Gunnebo hook latch kit is the replacement hinge that keeps the whole system working. Match the tool to the task.

How to Tell Which Scenario You're In

You don't need a flowchart to make this decision. You need three questions:

• Does the hook need to rotate under load? If yes, a Gunnebo swivel hook makes sense. If no, consider a fixed screw hook.
• How often will the hook be connected and disconnected? Daily use means a spring latch and easy access matter. Permanent installation means simplicity and fewer moving parts.
• What does the inspection environment look like? A swivel in a dirty, outdoor application needs regular lubrication. If that maintenance won't happen, a fixed hook may be safer.

Standards don't pick the product for you. ASME B30.26, the U.S. rigging hardware standard, defines acceptance criteria and inspection requirements for hooks. EN 1677-1 does the same for forged steel hooks in Europe. What those standards do is tell you what a compliant component looks like—and what records you need. They don't tell you whether a swivel or a screw hook is the right first choice. That's still on you, your engineering team, and your risk tolerance.

Five minutes of verification beats five days of correction.

The Bottom Line

Choose the Gunnebo swivel hook for high-cycle, multi-angle lifts. Choose the Durasteel screw hook for fixed, repeatable geometry. Choose the Gunnebo hook latch kit when a spring latch needs to be replaced. And when in doubt, go back to the standard. Check the WLL, check the connection, check the latch.

There's something satisfying about a hook that comes back for recertification after two years and still looks like a component you'd put on a new order. That's the payoff for getting the spec right at the start. Prevention is almost always cheaper than the correction.
