Set Screws / Grub Screws Manufacturer, Wholesaler, Supplier & Exporter to Colombo
Set screws (grub screws) thread fully into a component and bear directly on a shaft or mating part to prevent rotation or slippage, commonly in pulleys, collars, and gears. We manufacture and export these to DIN 913–916 in alloy and stainless steel. The Port of Colombo is one of South Asia's busiest transshipment hubs, serving both direct Sri Lankan buyers and onward regional distribution.

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.
Set screws (grub screws) do their job entirely below the surface of the component they're threaded into, which means the point geometry — not the thread — is what actually determines how well they hold a shaft in place. Buyers who order 'set screws' without specifying point type are leaving the single most important performance decision to whoever fills the order.
Colombo Shipping Notes
- • Colombo is one of the largest transshipment ports in South Asia.
Minimum Order — Container Quantity (Approx.)
A standard 20ft container (~20 tons) typically holds 3-5 million pieces of set screws in common sizes (M6-M8). Exact quantity depends on size and point type 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 Colombo Buyers Use Set Screws / Grub Screws
Shaft collars and pulley hubs
Cup-point set screws providing repeatable, removable shaft locking.
Permanent gear and coupling assembly
Cone-point set screws for higher-holding-power, less frequently disassembled joints.
Fine positioning in jigs and fixtures
Flat-point set screws bearing against a finished or hardened shaft surface without marking it.
Common Mistakes Buyers Make
Not specifying point type
Point geometry, not thread size, is the main performance variable — cup, cone, and flat points behave very differently under the same torque.
Using cone point on a shaft that needs to be reused
Cone points mark the shaft permanently and deeply — cup point is the better choice where the shaft may later be relocated.
Under-torquing a set screw on a vibrating shaft
Set screws rely entirely on point-to-shaft friction and indentation — insufficient torque is the most common cause of slippage in service.
Key Terms
- Cup point
- A set screw tip with a small circular ridge that indents the shaft for repeatable, removable holding power.
- Cone point
- A pointed set screw tip that digs deeply into the shaft for maximum, largely permanent holding power.
- Flat point
- A set screw tip that bears flat against the shaft without marking it, suited to finished or hardened surfaces.
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.
