Galvanized stud bolt is a double-end threaded fastener for PV brackets, cross arms, pole clamps, and steel frames. It is used with two nuts or nut-and-washer sets so the installer can tighten from both sides. The advantage is size control: diameter, length, thread pitch, threaded section, grade, and galvanizing method can be confirmed from the drawing before mass packing.

Product Advantages
1) Galvanized stud bolt keeps both ends ready for nut tightening, which is useful for clamp and bracket assemblies.
2) The grade can be matched with load position: 4.8 for regular fixing, 8.8 for main support joints, and higher grades only when the drawing requires them.
3) Matching galvanized accessories can be packed with the stud to keep the assembly finish consistent.
Main Applications
Used for photovoltaic support joints, pole clamps, cross arm assemblies, cable bracket sets, and general steel structure fastening.
Suitable for outdoor projects where threaded fasteners need zinc coating.
Order Notes
Confirm diameter, total length, thread length on both ends, grade, surface finish, and accessory quantity.
If B7 or another special grade is written on the drawing, the material and marking requirement should be confirmed before production.
