Hex Bolt Continuous Thread --drum--1/2 x

1/2 continuous thread hex bolt by drum is a hex head bolt for maintenance, light fabrication and general fastening with 1/2 in short or medium lengths. 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 1/2 diameter with continuous thread in short lengths; it is not the long full-thread reference. The material reported for the lot is 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 We do not publish single torque or load values because they depend on lubrication, coating, grip length, thread condition and engineering criteria.

Installation recommendations

• Verify whether the required thread is UNC or UNF; in inch fasteners, diameter alone does not ensure compatibility.
• 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, drawing or thread gauge.
• 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.
