Unexpected Downtime

A single ball stud bolt failure in a tractor linkage can cause $15,000/hour in lost revenue during harvest season.

Hidden Sourcing Costs

“Low-cost” imports often lack heat treatment consistency. 32% of rejected batches fail due to improper hardness (HRC) per our industry analysis.

Compliance Risks

Non-compliant angle bolts can void machinery warranties and lead to safety violations. ISO 9001 & CE marking are non-negotiable for serious buyers.

Powerful Factory Direct

Est. 2010, our 15,000 sqm facility houses 120+ high-speed cold heading machines and fully automated heat treatment lines. This vertical integration allows us to control every step of production, ensuring consistent quality for your angle bolt and ball stud bolt orders.

OEM/ODM Design Flexibility

Need a custom bend angle, thread length, or unique ball stud radius? Our in-house R&D team, led by senior engineers with 20+ years of experience, uses SolidWorks and FEA analysis to design fasteners that exactly match your assembly requirements.

Uncompromising Quality Assurance

Every batch undergoes tensile testing (UTM), hardness testing (Rockwell), and salt spray testing. We provide a full Material Test Certificate (MTC) with traceability from raw material to finished product.

"We switched to Boen for our ball stud bolts and saw an 18% reduction in steering linkage warranty claims. The consistency of the heat treatment is far superior to our previous supplier."

"Perfect angle bolt dimensions, every single batch. The DDP shipping solution they provided simplified our logistics tremendously. A true 5-star partner for European distribution."

"We needed a custom high-tensile angle bolt for a critical structural fix. Boen delivered prototypes in 10 days and the full order in 3 weeks. The FEA analysis report gave our engineering team complete confidence."

A: An angle bolt (square head or hex head) features a specific fixed bend angle (typically 30°, 45°, 60°, or 90°) used for securing wooden or steel members to a structure. A ball stud bolt features a spherical end, acting as a pivot or linkage point in mechanical assemblies, commonly found in steering and hydraulic systems. Selecting the correct one depends entirely on whether you need a rigid structural joint or a dynamic pivoting connection.

A: Absolutely. We offer full OEM/ODM customization. You can specify the exact thread length, shank diameter, and bend angle. Our minimum order quantity (MOQ) for custom angle bolts is typically 2,000 pieces, depending on the complexity.

A: Our QC process is comprehensive. For ball studs, we perform 100% dimensional inspection, hardness testing (HRC), tensile testing, and magnetic particle inspection (MPI) for surface defects. We also offer third-party inspection services (SGS, BV) upon request.

A: We ship globally via FOB, CIF, or DDP. Standard lead time for stock items is 2-3 weeks. For custom orders, typical lead time is 4-6 weeks, including tooling and sample approval. We have a dedicated logistics team to track your shipment until delivery.

A: Yes, we provide free samples for qualified OEMs and distributors. You only need to cover the shipping cost. We are confident in the quality of our angle bolts and ball stud bolts and encourage you to test them against your current specifications.

A: Every order comes with a 12-month warranty against manufacturing defects. We assign a dedicated account manager to handle any issues immediately. Our goal is to be a long-term strategic partner, not just a supplier.
