What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, this Bonost 2,300-piece kit is the most clearly positioned dual-standard assortment in the pool. The amazon.com listing documents zinc-coated machine screws, nuts, bolts, and washers across both metric and SAE sizes in three trays, and verified-purchase volume sits at just over 1,000 ratings averaging 4.6 stars. A garagejournal.com forum thread in the signal set surfaces it in a discussion specifically asking for a combined metric and SAE hex-bolt kit.
What reviewers liked
- Explicit metric and SAE coverage in one kit, confirmed by amazon.com listing
- Surfaced in a garagejournal.com forum thread specifically asking for combined metric+SAE bolt kits
- Zinc coating for corrosion resistance per the manufacturer listing
- Three-tray organization comparable to higher-volume competitors
Where it falls short
- Substantially less community discussion than the top pick — single r/BambuLab thread in the signal set
- Zinc-plated carbon steel, not stainless — wrong choice for wet or outdoor use
- No documented hardness grade in the surfaced signals, unlike the alloy-steel metric kit
- No wood or sheet-metal screws — strictly machine screws, nuts, bolts, washers

The gap between this pick and the Jackson Palmer choice is mostly in community footprint — there's substantially less specialist-subreddit discussion of the Bonost product in the data we have, with only a single r/BambuLab thread referencing the broader category. The product itself looks comparable on paper, and reviewers who want explicit dual-standard coverage in machine-screw form (rather than wood and sheet-metal screws mixed in) may actually prefer it. The honest synthesis is that it's an equally credible pick for buyers who specifically want both standards in one box and don't need the wood-screw coverage.

I'm thinking about ordering a good amount of 608 bearings, magnets, and M3 screws so I don't have to grab them so often. Is there anything else I should buy?
