- General repair
- Metric hardware
- Workshop stock
Hillman's 161-piece metric kit supplies matched M5, M6 and M8 hex bolts, nuts and flat washers in a divided reusable case, so you can complete a joint rather than fill a drawer, handy shelf stock for repairs. But it's metric-only (useless for SAE hardware), the zinc plating rusts outdoors, and bolts top out around 25-40mm for thin stack-ups.
Pros
- Real matched sets — bolts, nuts and washers in the same M5/M6/M8 sizes so you can actually complete a joint, not just fill drawers
- Reusable divided case keeps sizes sorted and is easy to grab off a shelf
- Cheap enough (~$10) to keep on hand for appliance, furniture and equipment repairs
Cons
- Metric only — useless for the SAE/inch hardware still common on US tools and machinery
- Zinc plating is indoor/light-duty corrosion protection; it will rust outdoors or in damp areas
- Bolts top out around 25–40mm long, so nothing here works for thick stack-ups

Frequently Asked Questions
- What makes this assortment more useful than a bolt-only box?
- It is matched sets — bolts, nuts and washers in the same M5, M6 and M8 sizes — so you can actually finish a joint instead of discovering the matching nut is missing.
- Does this kit cover US inch hardware?
- No, it is metric only, which makes it useless for the SAE/inch fasteners still common on US tools and machinery. Check which standard your repair uses before buying.
- How long are the bolts?
- Roughly 25-40mm at the top end, so nothing in the kit handles thick stack-ups. It is a repair-drawer assortment for appliances, furniture and equipment, and the zinc plating is indoor/light-duty only.
