Good Value Bulk Pack

Most sizes were useful for my workshop. The M6 and M8 bolts are very sturdy. Only giving 4 stars because the M3 count was lower than expected, but overall good value.

Missing Some Sizes

Quality is good but the assortment ratio was off. I needed more M5 bolts for my project and ran out quickly. Check the breakdown before purchasing if you need specific quantities.

Perfect Fit

Threads were clean and matched standard metric nuts perfectly. Great for repairing loose chairs and tables. The chamfered edge helps start the thread easily.

Excellent for DIY Projects

Used these for a custom desk build. The hex socket heads are deep enough to prevent stripping, and the steel quality feels premium. Highly recommend for anyone doing furniture assembly.

Strong and Durable

304 steel holds up well against rust. I used these in a humid basement for shelving units and there is no corrosion after six months. Threads are clean and easy to tighten.

5 FAQ

Q: Are these suitable for outdoor furniture?

A: 304 stainless steel offers high corrosion resistance and is suitable for covered outdoor areas. For direct exposure to saltwater or harsh chemicals, 316 grade is recommended.

Q: Do you sell M10 sizes in this series?

A: This specific kit includes sizes up to M8. We do carry M10 connectors in a separate heavy-duty furniture fastener listing.

Q: Is the thread left or right handed?

A: These fasteners feature a standard right-hand thread, which tightens clockwise and loosens counter-clockwise.

Q: What tool is needed for installation?

A: You will need a hex key or Allen wrench set that matches the specific bolt head sizes included in the kit (typically 2mm to 6mm).

Q: Can I return unused bolts if I ordered the wrong size?

A: Yes, unused items in original packaging can be returned within 30 days. Please refer to our return policy page for detailed instructions.
