Population, capital, currency, and languages from Wikidata (checked 2026-09-23); time zones from the IANA tz database. Duty and tax rates change and transit depends on carrier, routing, and port congestion, so figures marked indicative are confirmed against your product and destination port when we quote. Your customs broker should verify final landed cost.
Socket head cap screws earn their place in precision machinery for a specific reason: the cylindrical head lets a designer sink the fastener flush or below the surface without sacrificing the wrench engagement needed for a high-tensile joint. That combination — compact head profile plus class-12.9 strength — is hard to get from any other head style, which is why mold bases, jigs, and fixtures default to socket screws almost everywhere.

Why Socket Head Cap Screws Are in Demand in Karshi
- ▸Oil, gas and petrochemical facilities serving Karshi need socket head cap screws with traceable grades and mill test certificates.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) holds approximately 700,000-900,000 pieces of socket head cap screws in common sizes (M8-M10). Exact quantity depends on size and grade and is confirmed at quote time.
You don't need a full container to order. Hurain Engitech & Trade — the group Global Fasteners Exports operates under — regularly ships smaller, partial-container (LCL) orders of just a few pallets or boxes for buyers who don't yet need FCL volume, consolidated with other cargo to keep freight cost reasonable.
Where Karshi Buyers Use Socket Head Cap Screws
Mold and die assembly
Flush-mounting mold-base plates and inserts where a protruding bolt head would interfere with the tool.
Machine tool fixtures
Jigs and fixtures needing high clamping force in a compact footprint.
Robotics and automation frames
Compact, high-strength fastening in equipment with tight internal clearances.
Common Mistakes Buyers Make
Mixing metric and imperial hex keys
Forcing the wrong standard's key into a socket rounds it off, often destroying the fastener on the very first removal attempt.
Over-torquing class 12.9 screws in soft base materials
The screw may be rated for high torque, but the surrounding aluminum or plastic housing often isn't.
Specifying black oxide for a wet or corrosive environment
Black oxide offers minimal corrosion resistance on its own — stainless or a supplementary coating is needed outdoors or near coolant.
Key Terms
- Socket broach
- The internal hexagonal recess machined into the screw head to accept an Allen key or hex bit.
- Class 12.9
- A high-tensile alloy steel property class common on socket head cap screws, offering roughly 1220 MPa minimum tensile strength.
- Button head vs. socket head
- Button head screws have a lower-profile domed head for appearance or clearance; standard socket heads offer more bearing surface and strength.
How Ordering Works
- 1
Send your requirement
Product, grade/standard, quantity, and your preferred Incoterm (FOB/CIF/CFR).
- 2
Receive a quote
We confirm price, lead time, and MOQ based on ready stock or manufacturing time.
- 3
Sample & confirm (optional)
For new buyers, we can arrange samples before the full order is confirmed.
- 4
Production, QC & shipping
Manufacturing or sourcing, batch inspection, export documentation, and container loading.
HS Code & Customs Classification
Most fasteners fall under HS Chapter 73 (articles of iron or steel) or Chapter 74/76 for brass and aluminum items — the exact 8-10 digit subheading depends on the specific product and material. We include the HS code on the commercial invoice; confirm the applicable import duty with your customs broker, since rates vary by country and trade agreement.
Packaging & Export Labeling
Export packing is chosen to survive ocean freight and container loading without corrosion or damage: corrosion-protected paper or oil coating where needed, then cartons, drums, or bulk bags, palletized or crated for the container. We can match specific labeling, barcoding, or carton-marking requirements for OEM and repeat buyers.
