Bosch Clear Storage Box for Custom Case System

Why I added this clear storage box to my kit

Small parts organizers either earn their keep or they get banished to a drawer. After a few weeks with this clear storage box clipped into my Custom Case System, it’s in the “keeper” column. It’s a simple accessory—just a compact, clear plastic box with snap-in clips and a latch—but it solves a few everyday headaches around visibility, security, and modularity better than a lot of throwaway containers.

Design and build

The box is compact at roughly 3 x 3.2 x 1.03 inches and weighs next to nothing (about a tenth of a pound). The footprint is intentional: it fits the grid inside the Custom Case System while still being hand-friendly as a standalone. The clear shell makes it easy to see what’s inside without opening the lid, which, for me, is half the reason to use it. On a bench or in a dim van, being able to glance and grab the right bits or fasteners keeps the day moving.

The plastic feels sturdier than it looks. It’s not the thick, overbuilt kind you’d find on full-size organizers, but the sidewalls don’t flex under a squeeze and the lid doesn’t oilcan. The latch is a positive point: it clicks shut with enough resistance that I trust it in a tool bag. I can open it with one thumb, even with light gloves, and it snaps closed without fiddling.

Inside, snap-in/snap-out clips let you configure the interior to suit what you’re storing. This is a big upgrade over fixed compartments at this size. I set mine up with a narrow lane for 1-inch insert bits and a larger pocket for short screws and wall anchors. If I’m taking just a driver and a small kit into a site, this layout covers most of what I need.

Setup inside the Custom Case System

Clipping the box into the case is as straightforward as it should be. The side tabs engage with the Custom Case System rails with a solid click, and once it’s seated, it doesn’t slide around or rattle. The tolerances feel right—tight enough to be secure, not so tight that you’re fighting it during reconfigurations.

The real advantage is modularity. I routinely rearrange my case for the day’s tasks: a few of these boxes for fasteners, a couple of bit rails, and the larger components for hole saws or countersinks. Swapping layouts takes minutes and the box plays nicely with the rest of the system. If you’re already invested in the Custom Case System, this box is a natural add-on.

Capacity and what actually fits

Given the dimensions, this is a small-parts specialist. In practical terms:
- 1-inch (25 mm) insert bits fit perfectly and can be kept upright if you snap in the clips as a comb.
- 2-inch (50 mm) power bits will fit diagonally or laid flat, though you’ll carry fewer at a time.
- Short screws (up to about 1 inch), anchors, small washers, and wire ferrules are a comfortable fit.
- Anything long—3-inch bits, spade bits, nutsetters—belongs elsewhere.

The clips hold position well once snapped in. If you’re storing very small hardware (M2 screws, tiny washers), make sure the clips are seated fully; there’s not much of a gap, but a half-seated clip can allow slivers to migrate between sections.

In use on site

I carried one box in a jacket pocket for a week to see if the latch would pop open or the lid would fog. No issues: the latch stayed shut, and the plastic resisted scratches better than expected for this weight class. In the Custom Case System, I did a simple shake test—closed case, hard shake. The bits stayed put within the box, and the box stayed locked into the case. That’s the baseline I want.

The clear lid is legitimately helpful in low light or when you’re rushed. I can’t count how many times I’ve opened opaque organizers just to confirm what’s inside. Here, I can spot the 2 mm hex insert at a glance. Under harsh light the clear plastic can glare a bit, but tilting it a touch solves the problem.

Durability and maintenance

We’re still talking about plastic, so expectations should be reasonable. After a toss off a bench (roughly 3 feet) onto a rubber floor, the box came away without cracks and the latch stayed closed. The hinge is a molded plastic style; after repeated openings there’s no whitening or stress marks. I wouldn’t expect this to survive years of being stepped on, but for its use case—bits and small hardware—it’s durable enough.

Cleaning is easy. Mild soap and water restores clarity. I’d avoid aggressive solvents; clear plastics tend to haze under harsh cleaners. Labeling with a paint pen or label tape works well, and alcohol wipes remove paint pen markings without clouding the plastic.

Standalone vs. in-system

As a standalone, the box is handy for grab-and-go tasks. It slides into a tool pouch or a cargo pocket without bulk, and the secure latch means it won’t pepper your pocket with screws. The flat lid and base let you stack a few in a drawer, though there’s no interlocking feature, so they can shift if the drawer slams. A drawer liner solves that.

Inside the Custom Case System is where it shines. The clear lid, non-rattle fit, and clip-in convenience add up to less time spent hunting and reorganizing. The weight is negligible, so loading several doesn’t make the case feel heavy.

Limitations and nitpicks

• Capacity is naturally modest. If you need bulk fastener storage, this isn’t the tool; it’s for small assortment management.
• The interior clips are the hero and the bottleneck. Snap them in fully or very tiny hardware can sneak under a mis-seated edge.
• No integrated labeling panel. Stickers and paint pens work fine, but a recessed label spot would make rapid IDs cleaner.
• As a standalone, the boxes don’t interlock for transport. Not a deal-breaker, but worth noting if you plan to stack a lot in a bag.

Tips for better use

• Pre-sort by task: keep one box for common cabinet screws and anchors, another for 1-inch insert bits, and a third for specialty bits (tamper-proof, hex, square).
• Add a small rare-earth magnet dot under the bit lane if you want extra retention for insert bits; it keeps them from dumping when you open the lid sideways.
• Pop in a tiny desiccant packet if you’re storing carbon-steel bits in humid environments to reduce surface rust.
• Color-code labels by material (wood, metal, electrical) to speed up the grab.

Who will appreciate this

• Users already invested in the Custom Case System who want more fine-grained organization without jumping to a larger organizer.
• Techs and installers who carry a compact kit and need quick visual confirmation of bits and fasteners.
• DIYers who want to stop mixing screws and bits in one catch-all box and prefer a modular approach they can reconfigure.

Value

There are cheaper generic boxes, and there are pricier heavy-duty organizers. This one lands in the sensible middle: lightweight, purpose-built for the Custom Case System, and good enough to use on its own. The clear body, adjustable interior, and secure latch justify choosing it over repurposed containers or opaque minis.

Final recommendation

I recommend this clear storage box, especially if you’re using the Custom Case System. It slots in securely, keeps small bits and fasteners visible and contained, and the configurable clips make it more adaptable than fixed-compartment minis. As a standalone, it’s a reliable pocket-size organizer with a latch you can trust. Its limitations are tied to its size—this is not a bulk storage solution—but within its footprint, it’s a well-executed piece that reduces rummaging and speeds up small tasks. If you want to make a compact bit and fastener kit that you can rearrange at a moment’s notice, this box earns its spot.
