Hex Bolt Metric Class 8.8 UNC 8.8 Pitch 0.80

Hex bolt M5 class 8.8 pitch 0.80is a hex head bolt for small equipment assembliess, panels, housings, machined parts and supports where a hex head is required cabeza hex. 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 M5 pitch 0.80, different from M4 pitch 0.70 and M6 pitch 1.00; 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. 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 We do not publish single load or torque values because they depend on lubrication, nut, washer, thread condition, grip length and engineering criteria.

Installation recommendations

• Confirm that the nut has the same diameter, pitch and compatible class before tightening.
• Clean threads, holes and bearing surfaces before assembly to avoid false tightening.
• Do not mix metric thread with UNC or UNF; if in doubt, compare against a sample or drawing.
• Apply the torque or tightening method defined by engineering, considering lubrication and coating condition.
• Check grip length and remaining thread so the joint clamps on the parts, not on the thread end.
