Bonost 2300 Pieces Hardware Assortment Kit - Metric & SAE Machine Screw Assortment Kit with Assorted Nuts, Bolts, and Washers

Why I wanted a big, organized hardware kit

I keep a small shop’s worth of projects going—furniture fixes, shop jigs, appliance odds and ends—and I got tired of buying a full box of one fastener just to use four of them. I brought in the Bonost hardware kit to see if one stack of bins could cover the daily grind of household and hobby repairs without a dozen trips to the hardware store. After several weeks of use, it’s become the set I reach for first.

What you actually get

The kit spans both SAE and metric machine sizes, plus sheet metal screws, wood screws, and matching anchors. In practice, that means I’ve had the right option on hand for most day-to-day tasks:

• SAE machine screws, hex nuts, and flat washers in common diameters and lengths for light fixtures, cabinet hardware, small engine covers, and brackets.
• Metric machine hardware (M3–M8) for 3D printer assemblies, electronics enclosures, bike accessories, and European cabinetry.
• Sheet metal screws for thin-gauge steel and aluminum parts.
• Torx-drive wood screws in useful lengths that bite cleanly and minimize cam-out.
• Plastic anchors that pair with the included wood screws for basic drywall mounting.

The fasteners are zinc-plated carbon steel, so they resist rust better than raw steel and look tidy in finished installs. They’re not stainless and they’re not high-strength structural bolts—more on where that matters below—but for general repairs, the selection feels thoughtfully curated.

Build and organization

The assortment lives in three stackable cases with a printed fastener guide under the lids. Each style gets its own labeled compartment, and the bins are laid out sensibly: machine hardware grouped, wood/sheet-metal hardware grouped, and anchors separated so you’re not fishing through mixed parts. The stackable concept is genuinely handy on a shelf or rolling cart because it keeps the footprint small.

A couple of notes from setup and use:

• The labels are accurate and legible. I confirmed sizes with calipers and thread gauges; no oddball surprises.
• The internal dividers do their job, but very small parts can migrate if the case is jostled hard. I haven’t had a full-on mix-up, but I did find a couple of tiny washers in neighboring bins after a car ride. If you plan to travel with the set, a strip of painter’s tape over the lids eliminates the issue.
• The side-to-side stacking locks are convenient, but I don’t carry the entire set by the top case latch. I treat them as modular trays and lift one at a time. That’s the safer move with any multi-case organizer, and it’s kept mine intact.

Fastener quality and consistency

The most important part of a kit like this is the hardware itself. Here’s what stood out:

• Threads are clean and consistent. I ran a handful of sizes into new and existing threads without galling or burrs.
• Head geometry is reliable. Phillips heads are centered and deep enough to avoid cam-out with a decent bit; the Torx wood screws engage crisply.
• Washers are flat and uniformly punched. No rough edges or out-of-round pieces in the sets I used.
• The zinc finish is even. I didn’t see blotchy plating or flaking, and none of the pieces showed corrosion after a few shop weeks, including some time in a humid garage.

Again, these are general-purpose fasteners—not Grade 8 bolts or stainless marine hardware—but they’re solidly made for the wide range of tasks this kit targets.

In the shop and around the house

A few real jobs where the kit paid off:

• Rehanging a cabinet door: swapped a stripped hinge screw for a slightly longer sheet metal screw; threads bit and held without splitting.
• Rebuilding a push-mower handle: replaced a missing metric bolt and nut from the M6 assortment; fit perfectly and stayed tight with a drop of threadlocker.
• Mounting a garage power strip: used the included anchors and wood screws on drywall. The anchors set cleanly and held as expected for a light-duty load.
• Printer enclosure: tapped aluminum corner brackets and used M4 machine screws with washers; threads and head dimensions were consistent enough to make a neat, square assembly.
• Quick fixes: securing a loose electrical box cover, replacing the tiny screws in a tool handle, and spacing out a hinge with washers—all one-stop grabs.

Those are the moments this kit excels at: when you want to solve a small problem immediately without inventory stress.

Where it falls short

No kit is perfect, and a few caveats are worth noting:

• Case durability is “shop-grade,” not contractor-tough. The cases are fine on a shelf or cart and for normal carry, but I wouldn’t toss the stacked set loose into a truck bed. If you’re rough on gear or constantly mobile, you’ll want a more rugged organizer or to transfer the contents into one.
• Plastic anchors are basic duty. They’re appropriate for lightweight fixtures in drywall. For masonry, tile, or heavy shelving, use task-specific anchors or toggles.
• Not for high-stress applications. There are no hardened or stainless options here. If you’re working on automotive suspension, outdoor marine installs, or structural connections, choose the correct graded fastener.

Who this kit is for

• New homeowners who want a reliable “fix it now” drawer in one purchase.
• Makers, hobbyists, and tinkerers who bounce between metric and SAE projects.
• Light-duty shop work where having a breadth of sizes saves time.
• Landlords or maintenance techs who need a portable, organized general assortment for common repairs.

Who should look elsewhere: pros who need jobsite-tough cases and specialized fasteners (stainless, graded, self-tapping with specific tip styles) or trades where code-compliance dictates particular anchors and fastener grades.

Practical tips for getting the most out of it

• Inventory quickly on day one. Pop the lids and reseat any small parts that might have shifted. Add a desiccant packet to each case if your shop is humid.
• Mark go-to sizes. A fine-tip paint marker on the inside of the lid helps you find the “house favorites” you use constantly.
• Don’t carry the whole stack by one handle. Lift trays individually or strap the stack if you’re transporting it.
• Pair with a basic thread gauge and a decent bit set. You’ll identify threads faster and avoid chewing up heads. The kit’s screws are standard drives; quality bits make them feel better than they are.

Value and coverage

One reason I keep recommending an assortment like this is how it compresses small expenses and time costs. Instead of driving out for four M5 bolts and a handful of washers, I reach into a labeled bin and get on with it. Over a few weekends of fixes, that convenience is worth more than any one specialty box of screws, and the breadth of sizes means I’m rarely stuck improvising.

The bottom line

The Bonost hardware kit earns a spot in my shop because it does exactly what a general-purpose assortment should: it puts the most-used sizes—metric and SAE—within arm’s reach, organized in a compact footprint, with hardware that installs cleanly and holds up to everyday tasks. The cases are good enough for home and shop use but not bombproof; treat them with a little care, and they reward you with tidy organization and quick access.

Recommendation: I recommend the Bonost hardware kit for homeowners, hobbyists, and light-duty shop users who want a broad, well-labeled selection of fasteners at the ready. The hardware quality is consistent, the selection is comprehensive for everyday repairs, and the organization speeds up work. If you need jobsite-tough cases, stainless or graded fasteners, or heavy-duty anchors, plan on supplementing or transferring the contents—but for general repairs and projects, this kit is a smart, time-saving buy.
