Grade 5 UNC hot-dip galvanized hex bolt 3/8 is a hex head bolt for supports, light structures, enclosures and outdoor assemblies with coarse inch 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 Grade 5 UNC with hot-dip galvanizing; it is not A325 or galvanized Grade 1. The material reported for the lot is hot-dip galvanized 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 We do not publish single torque or load values because they depend on lubrication, coating, grip length, thread condition and engineering criteria.
