Are there any alternatives to auxiliary fastening parts?

Hey everyone, and welcome back to the shop—whether you’re a regular builder, a DIY junkie, or someone who’s deep in the weeds of sourcing parts for industrial projects, I know you’ve probably stared at a pile of auxiliary fastening parts (AF parts, let’s be real, no need to say the whole thing every time) and thought, “Is this the only way?” As a supplier of these little workhorses, I’ll be the first to admit we’ve all gotten stuck on relying on washers, brackets, clips, and the like to hold stuff together. But lately, I’ve been getting so many messages from clients asking if there are actual alternatives—stuff that doesn’t mean reaching for another tiny part that might get lost or add extra cost. Today, I want to break down some real, actionable alternatives, plus why we still stand by AF parts when they make sense, and how you can figure out what’s right for your project. Auxiliary Fastening Parts

First, let’s make sure we’re on the same page about what auxiliary fastening parts even are, because I’ve seen way too many people mix them up with actual fasteners (bolts, screws, nails—those are the ones that do the holding). AF parts are the extras: the flat washers that spread load under a bolt head, the U-clips that secure wires to a panel, the mounting brackets that hold a HVAC unit to a wall, the threaded inserts that make plastic parts tight enough to not strip. They’re like the sidekicks, not the heroes. And for a long time, they’ve been the default “just add it in” step for every build. But lately, material science and design innovation have been churning out alternatives that aren’t just gimmicks—they actually work for a lot of use cases.

Let’s start with the most obvious one: integrating fastening right into the base material. Wait, what? Yeah, I know it sounds out there, but it’s way more common than you think. Take injection-molded plastic parts, for example. Years ago, every plastic enclosure would need a metal insert to bolt a lid down, but now manufacturers can mold threaded bosses directly into the plastic. I worked with a client last month who makes medical device housings—they used to order 10,000 of those plastic inserts a week, plus the auxiliary washers to keep the bolt from digging in, and they switched to molded bosses. They cut their part count by two, no more stocking those tiny inserts, and the testing? They torque them to spec, and they don’t strip any more than the old system. For metal parts, you can do the same thing: tap threads right into a steel or aluminum component instead of using a nut as an auxiliary part. That cuts down on the number of parts to order, store, and install—no more dropping a tiny nut under a workbench mid-install, which we’ve all definitely done.

Another big alternative: adhesive bonding, especially structural adhesives. I know what you’re thinking—“Adhesive? It’ll fall off!” But modern structural adhesives are wild. They don’t just stick; they distribute load across the entire joint, not just at a single point like a bolt or clip. I’ve seen them used on everything from aircraft panels to wooden furniture. A cabinet maker I supply to was using metal mounting brackets (AF parts) for their floating shelves, which would sometimes tear out of drywall if someone loaded them with a ton of books. They switched to a structural epoxy adhesive rated for drywall, and now those shelves hold twice the weight without any brackets. The key here is picking the right adhesive for the material: epoxies for metal, urethanes for plastic, acrylics for mixed materials. The downside? They’re not as fast as bolting, and you need to make sure the surface is totally clean (no grease, no dust—we all hate that extra prep step). But if you’re doing a project where speed isn’t the top priority and weight matters? This is a game-changer.

Then there’s mechanical interlocking—like using the shape of the parts themselves to hold them together, no extra parts needed. Think of things like snap fits, which are super common in consumer electronics, but they’re popping up everywhere else too. A friend who works in automotive manufacturing told me their team recently redesigned a car door panel to use snap fits instead of the 12 plastic clips (our AF parts) they used to install. The snap fits are molded into the panel and the frame, and they lock together with just a press—no tools needed, no extra parts. There’s also crimping, though that’s been around forever, but modern crimping tools make it way more reliable for everything from electrical wires to metal tubing. I’ve used crimped connections for outdoor lighting projects, and they hold up way better than wire nuts (which are kind of like AF parts for electrical work) in rain and snow. The only catch with mechanical interlocking is that the parts have to be designed specifically for it—you can’t just retro-fit a snap fit onto a part that was made for bolts, usually. But if you’re starting from scratch, it’s a no-brainer for cutting part counts.

Wait, but hold on—before you go tossing all your AF parts in the trash, let’s talk about when alternatives don’t work. Because here’s the thing: auxiliary fastening parts aren’t around just to give suppliers like me a job (though I won’t lie, that’s a bonus). Sometimes, they’re the best option. Let’s say you’re building a deck: structural adhesives for the joists? No way, you need bolts or screws, and washers to keep the wood from splitting. That’s where AF parts come in. Or if you’re working on a project that needs to be taken apart later—like furniture you need to disassemble to move, or equipment that needs maintenance. Structural adhesives aren’t meant to be taken apart without damaging the parts, and snap fits can get worn out if you’re opening and closing them every day. That’s when those U-clips, mounting brackets, and washers save your life. They’re reusable, easy to replace if they get damaged, and you don’t have to redesign an entire part to use them.

I also want to talk about cost, because that’s the biggest thing for most people. Let’s do a quick breakdown: if you integrate fastening into the base material, you pay a little more in the initial design and molding setup, but over time, you save on inventory, installation labor, and shipping. For small projects, though, that setup cost might not make sense—buying a bag of washers for $5 is way cheaper than tooling up for molded bosses. Structural adhesives? A tube might cost $20, but if you only need one joint, that’s way more expensive than a $0.10 washer. It’s all about scale and your specific project needs.

Another thing I’ve noticed lately is that a lot of people are turning to recycled or alternative materials for fastening, even if they’re still using the basic AF parts. I started offering our washers in recycled stainless steel and even recycled plastic a couple years ago, and the demand has exploded. It’s not a total replacement, but it’s a way to make the existing parts work better for sustainability goals without having to overhaul your entire design. And honestly, that’s a middle ground a lot of us are missing—you don’t have to choose between sticking with what works and being eco-friendly.

Wait, let’s get real for a second—most of the time, I see people reaching for AF parts out of habit, not because it’s the best choice. I’ve been on job sites where a builder would grab four extra clips “just in case” when they only needed two, and end up wasting half the box. Or using a washer where a snap fit would have worked and saved them time. The biggest takeaway here is to stop asking “do I need an AF part?” and start asking “is this part actually necessary for this joint?” And if the answer is yes, great—we’ve got you. If not, there’s probably a simpler way.

I think part of the reason we’re seeing more alternatives now is that we’re all tired of overcomplicating things. The world of manufacturing and DIY has moved past the “add a part to fix it” mindset. We want things that are lighter, cheaper, easier to assemble, and more reliable long-term. That doesn’t mean auxiliary fastening parts are obsolete—far from it. They’re still the go-to for so many applications. But it’s good to know that there are other options out there, and that you don’t have to stick with the same old stuff just because it’s what you’ve always used.
