You're looking at shipments measured in dozens or hundreds of units, usually for automotive shops or general maintenance crews, and most buyers go with teh 8-inch and 10-inch sizes as the daily drivers. 6 to 18 inches covers what you'll actually reach for, and the drop forged carbon steel holds up pretty well under repeated clamping force without deforming—better than some budget alloy alternatives we've seen.
Sizes run 6, 8, 10, 12, 15, and 18 inches, weights vary from half a pound to about 2.5 pounds depending on which you pick. The adjustment mechanism uses a standerd coarse thread screw, so it's not fine-pitch but it locks tight quickly and won't slip under load if you set it properly. Surface treatment gets chosen at order: chromed polished, phosphatized black, or Ni-Fe alloy—the chromed version is easier to clean but the black finish hides shop grime better.
TPR double color dipping on the handle isn't just cosmetic; what it does is provide a slip-resistant grip even with oily hands, and the dual-materail construction gives you about 20 days or so before the outer layer starts showing wear in heavy use—still functional after that, though. One thing a buyer might not think to ask: the 15-inch size is actually the sweet spot for general plumbing work, but the 18-inch has better for stuck fasteners on heavy equipement. 47% of our reorders are the 12-inch, incidentally.
Each wrench comes individually wrapped in polybag or you can order bulk tray packs of 50 units or so—MOQ varies by size, usually 100 pieces for the 6- and 8-inch, and 50 for the larger ones. Warranty is 1 year limited, covers manufacturing defects but not user abuse or cracked jaws form prying—because of that it's not suited for that, just turning. We typically ship within 10 working days post-order confirmation, but confirm lead time on the 15-inch and 18-inch if you need more than 200 units.
So the grade 1 standard rating means it's been through hardness and torque testing, and you'll get a COA on request for batch traceability—actually requested more by maintenance contractors than mechanics. (Check the surface finish spec against your local environment; the chromed polished version handles humidity better than phosphatized for coastal shops.)
Anyway, the adjustment worm gear uses a pinned axle, not just pressed, so it won't back out during use like some imports. A three-step drop forge process and quench temper at roughly 48-52 HRC gives it that edge over cheap cast options—bending or galling is just not an issue with proper use.
We have 6, 8, 10, 12, 15, and 18-inch sizes. Yes, you can mix sizes in one order, but the minimum order quantity is 500 pieces total.
Lead time is usually 25-35 days after order confirmation and deposit, depending on the quantity and handle color specs.
Yes, we can provide a certificate of compliance for Grade 1 standards, plus test reports for materials and surface treatment upon request.
You can choose single or double color dipping for the TPR handle. Custom colors are possible with a minimum order of 1000 pieces.
Each wrench comes with a hang tag and is packed in a polybag. For bulk orders, we use export cartons. Custom packaging is available with a small extra cost.
