Every year, procurement teams lose $12,000+ per line due to fastener failures, delays, and hidden logistics fees. Here are the 5 biggest pain points we hear from buyers like you:
Distributors add 30–55% margin on countersunk coach screw and countersunk raised head screw lines. You pay for overhead, not quality.
Off-spec countersunk raised head screw dimensions cause poor flush seating, leading to rework costs of up to $2,800 per batch.
"Cheap" suppliers often quote FOB only. You eat the air freight when production lines stall — average $4,700 per emergency shipment.
Missing CE, UKCA, or RoHS declarations delay customs clearance. One European buyer reported a 14-day hold on a 40,000-piece countersunk coach screw order.
Stock suppliers can’t modify head angle, thread pitch, or material grade. You compromise your design — or pay a premium for custom tooling elsewhere.
We don’t just sell screws. We deliver certified, traceable, custom-engineered fastening solutions direct from our 10-year-old factory in Hebei, China — with full export compliance for USA & Europe.
Eliminate 3 layers of middlemen. Our countersunk coach screw and countersunk raised head screw lines are priced at 15–40% below distributor list prices — with full CIF, DDP, or EXW options.
CNC-controlled forming ensures ±0.1 mm tolerance on head diameter and angle. No more proud heads or countersink blowouts — guaranteed flush fit every time.
Stock lines ship within 24 hours. Custom OEM/ODM orders (including special thread pitches, lengths, and coatings) are produced and loaded in 12–18 working days.
Every batch includes ISO 9001, CE, RoHS, and FCC certificates. We also provide mill test reports, material traceability, and customized declarations for your customs broker.
Need a custom countersunk raised head screw with a 90° head angle, zinc-nickel plating, and a dog point? We’ll design, prototype, and validate in 7 days.
We provide digital SKU catalogs, barcode labels, and electronic packing lists compatible with SAP, Oracle, and NetSuite — reducing your receiving overhead by 22%.
All dimensions comply with DIN 7996 / ISO 1479 and ASME B18.2.1 standards. Custom sizes available upon request.

A German tractor OEM replaced their supplier with our countersunk coach screw (M12x80, 8.8 grade, HDG coated) and reduced fastener costs by 32% while improving pull-out strength by 11%.
A UK construction firm uses our countersunk raised head screw (M8x60, stainless steel 304) for decking and cladding — zero head protrusions reported across 12,000+ installations.
A Tier-1 supplier in Michigan specified our countersunk coach screw (M10x45, 10.9 grade, Geomet coating) for chassis brackets — 99.97% on-time delivery over 18 months.


A countersunk coach screw has a flat 90° head designed to sit flush with the surface, typically used in timber-to-metal or timber-to-timber structural applications. A countersunk raised head screw features a slightly domed top with a countersunk underside — it provides a more finished appearance while still sitting mostly flush. Both are available in multiple drive types and coatings.
For standard countersunk coach screw and countersunk raised head screw sizes, our MOQ is 5,000 pieces per SKU. For custom dimensions, materials, or coatings, the MOQ starts at 10,000 pieces. We also offer sample orders (50–200 pieces) for qualification testing — typically shipped within 5–7 working days.
Yes — every shipment includes ISO 9001:2015, CE, RoHS, and FCC certificates. We also provide mill test reports (MTR) for material traceability, and can issue UKCA, GS, or CB declarations upon request. Our compliance documentation is accepted by customs authorities across the EU, USA, and Southeast Asia.
We ship via FOB (Tianjin/Xingang), CIF, DDP, or EXW. Sea freight to major US/European ports takes 25–35 days. Air express (DHL/FedEx/UPS) delivers in 5–8 working days for sample or urgent orders. We also provide real-time tracking and digital packing lists for all shipments.
Absolutely. Our in-house tooling team can produce custom head angles (from 60° to 120°), non-standard thread pitches, and special drive recesses for both countersunk coach screw and countersunk raised head screw designs. Send us your drawing or sample, and we’ll deliver a free engineering review within 48 hours.
We accept T/T (30% deposit + 70% against BL copy), L/C (irrevocable at sight), Western Union, and PayPal for sample orders. For established accounts, we can discuss net 30/60 terms on a case-by-case basis. All payments are processed through our verified corporate bank account.
We follow a 3-stage QC process: (1) Incoming raw material inspection with chemical composition analysis, (2) In-process dimensional checks using CMM (coordinate measuring machine) every 500 pieces, and (3) Final random sampling per ANSI/ASQ Z1.4 (AQL 0.65). We also offer third-party inspection (SGS, TÜV, Bureau Veritas) at your cost.
We offer a 100% replacement or full refund for any product that does not meet agreed specifications. Claims must be submitted within 30 days of receipt with photographic evidence. We also provide free sample replacements for failed test batches. Our goal is zero defects on every shipment.
