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.

Procurement Director, UK Hydraulics Ltd

“We switched to Boen’s sealing socket head screws for our pump assemblies. Leakage rate dropped from 4.2% to 0.3%. The cost saving is phenomenal.”

Elena Vogt

R&D Manager, German MedTech

“PEEK socket head cap screws from Boen meet our ISO 13485 requirements perfectly. Delivery 18 days faster than our previous supplier.”

Carlos Rivera

“Zero defects in 50,000 PEEK cap screws. Boen’s quality system is as good as any top-tier Japanese supplier — at half the price.”

🔹 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.

🔹 What certifications do your sealing socket head screws have?

Our sealing screws are ISO 9001 and REACH compliant. For food contact, we offer FDA-grade materials. We also provide CE and RoHS declarations.

Anders Lindqvist

Supply Chain Manager, Swedish Automation

“We tested PEEK cap screws from three suppliers. Boen’s thread accuracy and surface finish were superior. Lead time 12 days to Stockholm. Highly recommended.”

Megan Foster

Senior Buyer, US Oil & Gas Equipment

“Sealing socket head screws with Viton O-rings — zero leaks in 6 months of field use. Pricing is 35% below our previous vendor. We’ve placed 3 repeat orders.”

Dr. Li Wei

R&D Director, Singapore MedTech

“Boen’s PEEK socket head cap screws passed our biocompatibility and sterilization tests with flying colors. Excellent technical support from the engineering team.”
