One-Stop Fastener Supply for Construction and Industry
Screws for drywall, timber, steel framing, roofing, panel and masonry work, produced to DIN, ANSI, BS and JIS and exported to North America, South America, Europe, South Africa and the Middle East.
19 Screw Lines Made on Our Own Heading Machines
Production workshop, materials, heat treatment, quality control, packing, warehouse and loading are all stages of our own plant, which is why head geometry and case hardness stay consistent from the first carton to the last.
Container Programmes on FOB CIF or DDP Terms
Minimum order 500 kg per item, mixed containers accepted, loading at Shanghai or Ningbo, with free samples against your final specification.
Six screw families, one supplier, one finishing plant
Every line below is made on our own heading machines and finished in the same plant, so an assembly specified across several families comes back with one consistent coating rather than three different shades of clear zinc.
Drywall Screws
Bugle and hi-lo thread drywall screws in coarse, fine and hi-lo forms, phosphated or zinc plated, for plasterboard onto timber and light-gauge steel.
See the range
Self-Drilling Screws
Drill-point screws in truss, pan framing and hex washer heads, including bonded EPDM washer versions for roofing and wall cladding.
See the range
Self-Tapping Screws
Sharp-point tapping screws in oval, pan framing and modified truss heads for window frames, light steel framing and sheet assemblies.
See the range
Wood Screws
Hexagon head and countersunk wood screws with Torx recess, in carbon and alloy steel, grade classes 4.6 to 10.9.

The process steps that decide whether a screw works
A screw that looks right and fails is almost always a heat treatment problem or a recess depth problem. Both are process controls rather than design choices, which is why we run heading, heat treatment, finishing and inspection in the same two plants instead of buying half-finished parts.
- Case hardness set in heat treatment so a drill point cuts steel without snapping.
- Recess depth gauged through each run, because cam-out is the largest time loss on site.
- Coating thickness measured rather than inferred from bath time.
- Pack counts verified before palletising, so the carton matches the label.

What the screws are actually holding together
The catalogue is built around five buying patterns rather than around what is easiest to produce.
Drywall and Interior Fit-Out
Board contractors buy screws by the tonne and judge them by how many strip, cam out or tear paper in a day's work.
What we supplyTimber Construction and Joinery
Structural timber work needs a drive that survives an impact driver and a coating that survives the weather.
What we supplyRoofing and Cladding
A roof fixing is a seal as much as a fastener, and it has to stay one for the life of the sheet.
What we supplyLight-Gauge Steel Framing
Steel stud framing is assembled faster than timber, and the screw is the only thing holding the tolerance.
What we supplyFurniture and Panel Manufacturing
Particleboard gives you one chance to seat a screw, and the underhead geometry decides whether the panel face survives.
What we supplySpecification notes worth reading before you order
Short engineering references on the decisions that go wrong most often.
Self-Drilling vs Self-Tapping Screws
When a drill point earns its cost and when a sharp point is the faster, cheaper and more reliable choice.
