⚠️ The Real Cost of Cheap or Unreliable Socket Head Screws
Every year, engineering and procurement teams lose thousands of dollars and critical lead time due to three core failures:
Inflated Pricing
Legacy suppliers charge 2–3× market price for PEEK socket head cap screws. A typical M6×20 PEEK cap screw can cost $4.50–$7.00 from traditional distributors — we deliver the same at $1.85–$2.95.
Inconsistent Quality
Molded threads, burrs, and incorrect hardness values cause assembly failures and field returns. In 2025, a major automotive tier-1 reported 12% rejection on imported PEEK fasteners — we maintain <0.2%.
Shipping & Lead Time Chaos
Supply chain disruptions cause 8–14 week delays from European suppliers. Our 15-day express from China to USA/Europe via DDP keeps your production line running.
📉 Result: 20–35% higher total cost of ownership than necessary.

❓ Frequently Asked Questions — PEEK Socket Head Cap Screws & Sealing Socket Head Screws
🔹 What is the difference between a standard PEEK socket head cap screw and a sealing socket head screw?
A sealing socket head screw incorporates a pre-applied O-ring or undercut seal (PTFE, Viton, or NBR) to prevent fluid or gas leakage. Standard PEEK cap screws provide excellent chemical resistance but no sealing function. Use sealing screws for hydraulic, pneumatic, and fluid containment applications.
🔹 Do you offer custom thread lengths or drive types (Torx, Hex, etc.)?
Yes, 100% OEM/ODM capability. We can customize thread length, head style, drive type, and sealing compound. Minimum order for custom PEEK socket head cap screws is 500 pcs per size. Send your drawing to shuan@fastenboen.com.
🔹 What are your payment terms?
We accept T/T (30% deposit, 70% before shipment), L/C, and PayPal for sample orders. For established customers, we offer net 30 after credit evaluation. All prices are FOB Shanghai / CIF / DDP.
🔹 How do you ensure the quality of PEEK socket head cap screws?
We follow ISO 9001:2015 with in-house testing: tensile, hardness, dimensional, and salt spray. Material certificates from Victrex or Solvay are provided. Third-party testing (SGS, TÜV) is available at cost.
🔹 What is the typical lead time and shipping cost to the USA?
Stock items: 2–3 days after order. Custom PEEK screws: 15–20 days air express (DDP), 25–30 days sea freight. Shipping cost for a sample order (1 kg) to USA via DHL/FedEx is approximately $35–$55.
🔹 Can I get free samples for testing?
Yes, we offer free samples for standard sizes (up to 5 pcs) with free shipping for qualified buyers. Just pay the courier fee or use your account. Contact grace@fastenboen.com to arrange.
