ChinaKey features
High strength carbon steel is hot dip galvanized and roll threaded to ISO metric tolerances, with a material test certificate and heat number documenting every production heat
ISO 724 metric thread profile and ISO 898-1 class 8.8 properties cover M12 to M30 square head bolts, with 580 MPa minimum proof load, 800 MPa tensile and 500 to 1000 hours salt spray
Hole misalignment and coating build up on steel pole flanges push crews to hammer bolts and damage threads, while ISO tolerance threads and controlled galvanizing let the machine bolt start by hand
Post galvanizing thread gauging keeps the square head machine bolt easy to run up, so nuts turn smoothly on steel pole crossarm flanges during installation and later pole top maintenance
Bars are forged or cold headed, roll threaded, heat treated to class and hot dip galvanized with batch verified thickness, and OEM orders follow the steel pole drawing for grip length and head marking
Production runs under an ISO 9001 system and every batch is issued with a material test certificate, coating report and dimensional records for steel pole compliance files
Each lot keeps its heat number from rolling to shipment so the MTC and COA match the goods delivered, and proof load and coating thickness are checked before release
Matched square nuts, locknuts and galvanized washers can be supplied with every machine bolt so each steel pole flange connection arrives as one complete fixing package
Factory direct pricing with OEM and ODM service, low MOQ trial orders, free samples for approval and a 15 to 30 day lead time on bulk machine bolt shipments

AI-Powered supplier vetting
SummarySokun is a limited company with 21 employees, related companies, and product coverage including fasteners, machined parts, and stamping parts. It supports customization from samples and designs, offers ODM services, and reports OEM service for well-known brands. Quality processes include quality assurance, documented inspection instructions, and complaint-handling records, although finished-product inspection is random and only one quality inspector is reported. Production-related strengths include in-stock capability, CNC and punching equipment, and one-month stated lead times in both peak and off-season periods. Key limitations are the absence of a valid manufacturing-capacity contract with related subcontractors, no overseas warehouse, branches, agents, or showrooms, and no documented R&D audit materials, new products in the past year, or R&D patents. Financial credibility cannot be determined from the provided information.
After-Sales capabilityThe supplier has a clear customer-complaint procedure with followed records and accepts several quotation and payment terms. However, it has no overseas warehouse, showroom, agent, or branch, and reports zero countries with overseas services, limiting evidence of localized after-sales support.
R&D capabilityThe supplier provides ODM and multiple customization-based design services, but reports no new products during the past year, no available SDK, no R&D audit documentation, and zero R&D patents. These facts indicate design support but limited documented evidence of independent innovation.
Production capacityProduction evidence includes CNC and punching equipment, in-stock capability, one-month lead times in both peak and off-season, and a product scope aligned with machined and stamping parts. Nevertheless, there is no valid manufacturing-capacity contract with related subcontractors, which creates a documented capacity-governance weakness.
Customization capabilityThe supplier explicitly supports customization from samples, designs, full customization, flexible customization, and minor customization, and also offers ODM services. This is direct evidence of broad customization capability.
Product Q&A
Q:1. What types of power line hardware and power fittings do you supply?
A:
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.
Q:2. Do you manufacture custom and non-standard power line hardware?
A:
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.
Q:3. What power line fasteners can you manufacture?
A:
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.
Q:4. Can you supply complete power line hardware according to a BOM or project list?
A:
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.
Q:5. What information do you need to quote power line hardware?
A:
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
