We'd recommend honestly that if you're expecting to torque down aircraft-grade bolts daily, these probably aren't for you — they're great for general mechancial work but not for every extreme use. Actually, for most professional maintenance and assembly jobs, basically what happens is the chrome vanadium steel holds up well and the chrome plating resists rust better than the cheaper unpainted stuff we tested.
Most procurement folks we deal with go with the 6-32mm set because of that it covers all common sizes without needing a second order, and it fits American, British, German, and European standard on the same wrench. We usually have about 200 sets in stock, but confirm lead time if you need more than 50 units or so — we can ship within 14 to 20 days on larger quantities.
Each wrench's precise machining — and we've measured them — gives a tighter tolerance than many generic sets we've seen, though the 6mm end can feel a bit snug on some older fasteners. The working mode is manual, obviously, and the handle color is just the standard metallic chrome finish, nothing fancy.
Shipping terms our company can do FOB or CIF depending on your preference, payment is typically T/T with 30% deposit and 70% before shipment, but we're flexible for regular orders. The packging info you'll want: each set comes in a canvas hang bag, and if you order 20 sets we'll pack those into one carton (usually 27kg or so per carton). COA and TDS are included with each batch, no extra charge.
One concrete thing that's good to know — the 22mm wrench in the 6-32mm set is slightly thicker at the jaw than some others we've handled, which gives it better grip on rusted nuts. It's not suited for automotive brake line work where clearance is tight; for that you'd want a slimmer profile.
Also, the suface treatment is chrome plated, not painted, so it doesn't chip off under normal use — we've had a buyer complain about that once with another brand we dropped. So that's the spec data you need: sizes 6-17mm, 6-22mm, or 6-32mm sets avaliable form us.
MOQ for the canvas bag option is 1 set, so you can start with just one to test the market. For carton packaging, it's 20 sets minimum.
Yes, we can supply a material test report for the CRV steel and a chrome plating thickness certificate upon request. Just let us know when you place the order.
The 6-32mm set includes every millimeter size from 6mm up to 32mm, so you get 27 wrenches total. The 6-17mm and 6-22mm sets skip some sizes, but the full range covers all.
Standard is chrome plated, but we can do black oxide or phosphate coating for large bulk orders. Minimum for custom treatment is usually 500 sets.
The canvas hang bags are sturdy for retail display, but for bulk export we recommend the carton option with 20 sets per box, which protects better during transit.
