Hex bolt grade 5 UNF blackis a hex head bolt for machinery, spare parts and assemblys inch-thread that requieren fine thread UNF and strength grade 5. At TECTUL it is quoted per unit and by actual available size, cross-checking diameter, length, pitch, material and standard before confirming price. This reference is differentiated by UNF black grade 5, not UNC grueso or metric; therefore, it should not be replaced with a similar related item only because it has a hex head. The material reported for the lot is carbon steel black. For class 8.8 and 10.9, selection is based on ISO 898-1 as the reference for mechanical properties; for DIN 933, DIN 960 or DIN 961, full, partial or fine thread geometry is validated against the drawing. For ASTM A325, A490 or A394 bolts, the project standard defines the bolt, nut, washer and assembly. We do not publish single load or torque values because they depend on lubrication, nut, washer, thread condition, grip length and engineering criteria.

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.
