M4 hex bolt class 8.8 yellow zinc pitch 0.70 is a hex head bolt for compact assemblies, covers, guards, panels and machined parts with M4 metric thread. At TECTUL it is quoted per unit and by actual available size, cross-checking diameter, length, pitch, material, finish and standard before confirming price. This reference is differentiated by M4 pitch 0.70 and yellow zinc finish; it is not M5 pitch 0.80 or M4 without a specified finish. The material reported for the lot is yellow zinc plated carbon steel. For class 8.8, 10.9 and SAE grades, selection must respect the requested mechanical property; for DIN 933, DIN 931, DIN 960 or DIN 961, full, partial, standard or fine thread geometry is validated according to the drawing. For ASTM A325, A490 or A394, the project standard defines bolt, nut, washer and assembly. We do not publish single torque or load values because they depend on lubrication, coating, grip length, thread condition and engineering criteria.

The price depends on size, length, quantity, finish, standard and availability. TECTUL quotes per unit with the exact reference requested.
The difference is the yellow zinc finish. If the drawing only calls for M4 class 8.8, this finish should be confirmed when surface protection or visual identification is required.
It is installed by verifying diameter, pitch, usable length, compatible nut and assembly torque according to the equipment or drawing. Do not force a thread that does not start freely.
Send diameter, length, pitch or thread, quantity, material, finish, required standard and a photo or drawing if you are replacing an existing reference.
The sale is handled per bolt unit unless the quotation specifies a set. Indicate whether you need a nut, flat washer, lock washer or structural set.
Yes. TECTUL dispatches to Bogotá, Medellín, Cali, Barranquilla and other cities in Colombia depending on availability and carrier.
