โ ๏ธ The Hidden Costs of Sourcing Small Fasteners Abroad
When you order 2.5 mm socket head cap screw or 2mm socket head cap screws from unreliable suppliers, every weak link in the chain costs you time, money, and reputation. Here are the most common risks our customers faced before partnering with Boen:
๐ด Inconsistent Hardness & Fit
A German automotive Tier-1 supplier reported 12% rejection rate on M2.5 screws due to hex socket wear. That's 12% scrap, rework, and delayed production line.
๐ด Hidden Shipping & Customs Delays
One UK machinery buyer paid 37% more than quoted because of unplanned air freight and customs holds โ no certificate of origin, no CE mark.
๐ด MOQ Mismatch & Inventory Waste
Many suppliers demand 50,000+ pieces per size. For SMEs, that ties up capital in slow-moving inventory. You need flexible MOQ, not a warehouse gamble.
๐ด No Traceability, No Accountability
When a batch fails, who do you call? 60% of importers say they can't get a timely response from their fastener supplier. We provide batch-level mill certs and 24h response.
๐ก Result: Our customers typically reduce total cost of procurement by 18โ28% after switching to Boen's factory-direct model.

โ โ โ โ โโ Frequently Asked Questions โ 2.5 mm & 2 mm Socket Head Cap Screws
The primary difference is thread size: M2.5 has a 2.5 mm thread diameter with a 2.0 mm hex socket, while M2 has a 2.0 mm thread diameter with a 1.5 mm hex socket. The M2.5 offers higher tensile strength (typically 12.9 grade) and is used in applications requiring greater clamp load, such as automotive brackets and machinery. The M2 is ideal for compact electronics and precision instruments where space is limited.
Our standard MOQ is 5,000 pieces per size for stock materials (alloy steel, stainless steel). For custom lengths or special coatings, MOQ is 10,000 pieces. We offer sample orders (100โ200 pcs) for qualification at a small premium. This flexibility helps SMEs avoid overstocking.
Yes. Every shipment includes a Certificate of Conformity (ISO 9001) and a Mill Test Report showing chemical composition and mechanical properties (hardness, tensile strength, yield). We also provide CE, RoHS, and FCC declarations upon request.
Standard lead time is 12โ18 working days after sample approval. For urgent orders, we offer expedited production (7โ10 days) with a 10% surcharge. Shipping to Europe/USA takes 5โ10 days via air freight or 20โ30 days by sea.
Absolutely. We offer OEM/ODM customization including custom head stamps (e.g., your brand or grade), special packaging (bulk bags, retail boxes, blister packs), and barcode labeling. Minimum for custom marking is 20,000 pieces per size.
