The consensus
What reviewers found
Synthesized across the trust-weighted source mix below.
Across the reviewers we read, this Bonost 2,300-piece kit earns its place as the dual-standard option: it pairs metric and SAE machine screws with assorted nuts, bolts, and washers across three trays, and holds a 4.6 average over roughly 1,015 verified-purchase ratings. For buyers who don't know in advance whether a project will call for inch or millimeter hardware, customer feedback frames this breadth as the main draw. As with most combo kits, reviewers note the tradeoff inherent in covering two standards: per-size counts are smaller than a dedicated single-standard set, so heavy users of one specific size may exhaust it.
What reviewers liked
- Covers both metric and SAE in one kit, reducing guesswork
- Strong 4.6 average across ~1,015 verified-purchase ratings
- Three-tray layout aids organization and reuse
Where it falls short
- Covering two standards means fewer pieces per individual size
- No expert or lab testing available to verify material quality
- High total piece count includes sizes many users won't need

As with most combo kits, reviewers note the tradeoff inherent in covering two standards: per-size counts are smaller than a dedicated single-standard set, so heavy users of one specific size may exhaust it. No independent testing was available for this candidate, so claims about material strength rest on customer impressions rather than measured data. On the evidence we have, it is a well-rated, versatile catch-all for mixed workshops.
