Got the H066 hex wrench set here, and we run 40,000 pieces a day through ISO9001 lines, so batch consistency is pretty much a given — every lot gets pulled for torsion and hardness testing before we ship, usually with a COA ready to go if you need it.
Basically, it’s for anyone doing mechancial repair or assembly who needs a mix of metric and SAE sizes from 1.5mm up to 10mm, and teh manual working mode isn’t flashy but it holds up fine on a standard shop floor.

We do a retest policy if the COA doesn’t match what you’re seeing in your own QC, but that’s rare since the electrophoresis coating tends to keep the steel consistent across batches (give or take 2-3 working days for the retest turnaround).

For bulk orders, we quote 7-10 working days lead time, and the MOQ is literally 1 set for a sample order, so you can check the tolerance before committing.

Also, the handle color is customizable if you want it metallic or something else, and packging options are polybag, color box, or hanging case — we’ve seen some buyers prefer the hanging case for retail display, but it’s not necessary for workshop bins.
Not best tool for precision electronics work, though; the 1.5mm size is there, but the coating adds a vague (~0.1mm or so) thickness that might bug you on small screws, so we usually warn folks about that upfront.
You can start with a single set as a sample order—MOQ is just 1 set. For custom handle colors, we'll run that on any order size, but samples are the quickest way to check the color match.
Yes, our factory is ISO9001 certified, and we include a copy of the certificate with every bulk order. Just let us know if you need it in a specific format for your records.
We can produce custom sizes outside the standard 1.5mm-10mm range for bulk orders, but it'll need a quick check on tooling. Let us know the exact sizes and quantities, and we'll confirm feasibility.
We offer polybags, color boxes, and hanging cases. Yes, we can print your logo on the packaging—just send the artwork, and we'll handle the rest. For samples, we usually go with polybags unless you specify otherwise.
Yes, our daily capacity is 40,000 pieces, so a 40,000-set order fits within that range. Lead time is 7-10 working days after order confirmation, but we'll confirm the exact timeline once we know the packaging and custom details.
