⚠️ The Real Cost of Using the Wrong Brass Fasteners
🔴 Corrosion & Downtime
In marine & chemical environments, subgrade brass screws fail within 6–12 months. One production halt costs $3,500–$8,000/hour in lost output.
🔴 Hidden Supply Chain Costs
Broken lots, inconsistent thread tolerances, and delayed shipments force emergency orders — 18–30% cost premium on expedited logistics.
🔴 TCO Blind Spots
Buying on unit price alone? Field failures, replacement labor, and warranty claims inflate total cost by 40–60% over 3 years.
🔴 Compliance Headaches
CE, RoHS, REACH — one missing certification can block your entire shipment at customs. 2–4 weeks clearance delay is common.
👉 You need a supplier that delivers precision, compliance, and speed — every time.

💬 Real Conversations with Our Customers
❓ Frequently Asked Questions About Brass Socket Head Screws
1. What is the difference between brass socket head cap screws and regular brass screws?
Brass socket head cap screws feature a cylindrical head with a hexagon socket drive, allowing higher torque and a cleaner appearance. Standard brass screws often have slotted or Phillips heads and lower tensile strength. Our cap screws meet DIN 912 / ISO 4762, delivering 20% more clamping force than equivalent pan-head screws.
2. Do you offer custom sizes and OEM/ODM services?
Yes. We specialize in OEM/ODM brass socket head screws with custom thread lengths, head diameters, drive types, and surface finishes. Minimum order quantity for custom is 5,000 pcs. Send your drawing or sample for a free design review.
3. What shipping methods do you use for USA and Europe?
We ship via FOB (Tianjin/Qingdao), CIF, DDP, or EXW. For USA/Europe, standard sea freight takes 25–35 days. Air express (DHL, FedEx, UPS) delivers in 5–8 days. We also offer consolidated shipping to reduce per-unit freight cost by up to 30%.
4. Are free samples available for testing?
Absolutely. We provide free samples (up to 20 pcs) for qualified buyers. You pay only the shipping cost. Samples are produced from the same production line as bulk orders, so you can validate fit, finish, and performance before committing.
5. What is the typical lead time for bulk orders of brass socket head cap screws?
For standard sizes (M4–M12) in stock: 3–5 days. For non-standard or custom sizes: 15–25 days depending on quantity and finishing requirements. We offer split-order options — partial shipment within 10 days to keep your line running.
6. What certifications do your brass fasteners comply with?
Our products are certified ISO 9001:2015, CE, RoHS, and REACH compliant. UL, FCC, and CB certifications are available upon request. We also provide full traceability documentation including mill certificates and inspection reports.
7. How do you ensure consistent quality across large volumes?
We follow AQL 0.65 (normal level II) per ISO 2859. Every batch undergoes dimensional inspection, hardness testing (Rockwell B), and salt spray testing. We also maintain batch traceability by heat number and production date.
8. What payment terms do you accept for international buyers?
We accept T/T bank transfer, L/C, PayPal, and Western Union. For first-time buyers, we typically require 30% deposit with 70% balance before shipment. Long-term partners may qualify for net‑30 terms after 3 successful orders.
