Black flat washer per kilo is a TECTUL reference for supplying carbon steel flat washers for workshop, maintenance or production when a black finish is sufficient. Its function should be read from the washer type: flat washers distribute load and protect the surface, split lock washers help retain tightening, toothed washers bite into the bearing face, and sealing washers work by deformation or compression. In this product the main material is black carbon steel and the technical family is flat washer for inch threads. It differs because it is sold by kilo and not per unit, with actual counts per size reported in the lot. To quote without errors, report size, quantity, bolt or nut type, working environment, required finish and whether the purchase will be by unit or by kilo. We do not recommend substituting with a similar part if the drawing requires ASTM F436/F436M, 316 stainless steel, a specific gauge, hot-dip galvanized finish or a special reference.

The price depends on size, material, finish, quantity and presentation by unit or kilo. At TECTUL we quote using the actual order size.
The per-kilo presentation is suitable for high consumption; the unit presentation allows exact purchase when few pieces or assorted sizes are required.
Protect the assembly if it will be exposed to humidity or outdoors, because black finish is not equivalent to galvanized coating.
Send size, quantity, material, finish, bolt or nut type, application and delivery city. If you are replacing a special part, a photo helps.
They are not equivalent. The flat washer distributes load; the split lock washer helps retain tightening. In many assemblies they can be used together, but they perform different functions.
Yes. TECTUL dispatches to Bogotá, Medellín, Cali, Barranquilla and other cities in Colombia, depending on availability and carrier.
