🔩 Premium Aluminum Socket Head Screws & Assorted Socket Head Cap — Buy Direct for 40% Less

⚙️ Stop overpaying for lightweight, corrosion‑resistant fasteners. We deliver factory‑direct aluminum socket head screws and assorted socket head cap screws that meet ISO, ASTM & RoHS — with lead times as short as 7 days.

❌ 32% higher failure rate

Low‑grade 6061-T6 screws from unknown sources crack under torque. A single failure in an aerospace jig costs $12,000+ in downtime.

📦 Inconsistent dimensions

“Assorted socket head cap screws” that vary ±0.15 mm cause assembly jams. Our clients report 17% scrap reduction after switching to Boen.

🚢 Hidden logistics costs

Split shipments, delayed customs docs, and poor packaging add 18–25% to your landed cost. We ship FOB, CIF, or DDP — no surprises.

📄 No compliance traceability

Without CE, RoHS or ISO 9001, your procurement team risks non‑compliance audits. Every Boen batch comes with full mill certs.

1. What grades of aluminum do you use for socket head screws?

We primarily use 7075-T6, 6061-T6, and 2024-T4. 7075 offers the highest strength for critical applications; 6061 is best for general use and corrosion resistance. All grades are fully traceable to mill certificates.

2. Do you offer assorted socket head cap screws in mixed size kits?

Yes! We provide custom assortments in tray packs, poly bags, or bulk. Popular kits include #4–3/8″ UNRC and M3–M12 metric. Request a quote and we’ll tailor the mix to your BOM.

3. What is the minimum order quantity (MOQ)?

For stock items: MOQ 500 pcs. For custom OEM orders: 2,000 pcs per size. Need a prototype? We offer low-volume samples (50 pcs) for qualification.
