Wholesale Double End Stud High Strength ASTM A193 B7 Hot Dip Galvanized For Utility Pole Crossarm Connection Bolting

Product Description

Product Highlights
Chromium molybdenum alloy steel, quenched and tempered to ASTM A193 B7 with a minimum tensile strength of 860 MPa, suits crossarm connection studs that must hold clamp load under conductor tension. Heat number traceable mill certificates document composition and mechanical properties for each heat, meeting utility material verification requirements for structural bolting.
Double end studs manufactured to ASTM A193 dimensional practice with metric or inch threads from M12 to M36, both ends threaded and the center section left plain as drawn. The hot dip galvanized finish provides 500 to 1000 hours of neutral salt spray resistance, protecting the stud where it passes through crossarm steel and pole attachments.
Crossarm connections loosen when threads corrode and when undersized studs yield under unbalanced conductor loads, allowing the arm to drop or twist. A B7 stud with galvanized threads keeps preload stable and resists rust seizure, cutting retightening rounds and preventing crossarm failure from degraded bolting while the line stays energized.
Studs are machined to length, heat treated, roll threaded and hot dip galvanized with thread verification completed after coating. Matched hex nuts, lock washers and flat washers are packed with each stud, and export packing in cartons, pallets or steel crates protects the threads for sea freight to the project site.
ISO 9001 factory supplies MTC, COA and salt spray documentation per order for complete traceability. Custom thread lengths and diameters are accepted for OEM and project work, MOQ is practical for stock sizes, free samples are available, the production lead is 15 to 30 days, and factory direct pricing applies for utility and EPC buyers.

Frequently Asked Questions
1. What types of power line hardware and power fittings do you supply?
We supply a wide range of power line hardware and power fittings for transmission and distribution systems, including suspension clamps, strain clamps, connecting hardware, pole line hardware, U bolts, eye bolts, grounding hardware, guying hardware, anchors, insulator fittings, OPGW/ADSS fittings, and related utility fasteners.
We also support custom products based on drawings, samples, and project specifications.
2. Do you manufacture custom and non-standard power line hardware?
Yes. We manufacture custom and non-standard power line hardware according to customer drawings, samples, technical specifications, and application requirements.
Our engineering team can review dimensions, materials, tolerances, surface treatment, and manufacturing feasibility before production. OEM and ODM services are available for utilities, EPC contractors, equipment manufacturers, wholesalers, and distributors.
3. What power line fasteners can you manufacture?
We manufacture a broad range of power line fasteners and pole line bolts, including U bolts, pole line square head machine bolts, carriage bolts, double arming bolts, eye bolts, spool bolts, threaded rods, nuts, washers, and other galvanized fasteners used in utility structures.
Custom dimensions, threads, lengths, and configurations can also be produced according to drawings or project requirements.
4. Can you supply complete power line hardware according to a BOM or project list?
Yes. We can supply mixed power line hardware based on BOM lists, drawings, or project specifications.
Different products such as clamps, bolts, shackles, link plates, eye fittings, grounding components, pole line hardware, and accessories can be consolidated into one order and shipment.
This helps EPC contractors, utilities, and distributors simplify purchasing and reduce the number of suppliers required for a project.
5. What information do you need to quote power line hardware?
For an accurate quotation, please provide as much of the following information as possible:
• Product name or BOM list
• Drawings in PDF, CAD, DWG, STEP, or similar formats
• Dimensions and thread specifications
• Material requirements
• Surface treatment or galvanizing requirements
• Mechanical or load requirements
• Applicable standard, if required
• Quantity and packaging requirements

If complete specifications are not available, you can also send photos or samples for technical evaluation.
6. How do you ensure the quality of power line hardware?
Quality control is carried out throughout material inspection, manufacturing, dimensional inspection, surface treatment, assembly, and final inspection.
