Better Fastener Industry Co., Ltd. manufactures and supplies a complete screw range from our base in Hangzhou, China — slotted, Phillips, hexagon socket, square slot, Torx, set, hand, tapping, rolling, drilling and wood screws in carbon steel, stainless steel and low-alloy steel. Founded in 2001 as a washer factory and expanded into a comprehensive fastener enterprise in 2010, we now run integrated production for screws, bolts, nuts and washers, with more than 20,000 tons of annual output and export to North America, Europe, Australia and other high-end markets.
Our Carbon Steel Screws are self-contained threaded fasteners that drive directly into the workpiece without a separate nut. Cold heading and thread rolling produce sharp points and well-defined thread profiles for clean penetration in wood, sheet metal, plastics and machined components. We build to DIN, ISO, ANSI, ASME, BS, EN, GOST, JIS, AS and KS specifications, and we support both standard and drawing-based custom production.
Our Screw Range and Where Each Type Fits
Every drive format in our catalogue solves a specific assembly problem — tool access, torque control, flush finish or substrate penetration. The table below maps our screw families to their typical installation conditions.
| Screw Family | Drive / Feature | Typical Application Fit |
|---|---|---|
| Slotted Screws | Single straight groove, flat-blade driver | Wooden furniture, door and window hardware, decorative panels, legacy equipment maintenance |
| Phillips Screw | Cross recess, self-centering, cam-out torque limit | Consumer electronics, home appliances, automotive interiors, communication equipment |
| Hexagon Socket Screws | Internal hex recess, high torque, flush counterbore | Machine tools, moulds, automation equipment, hydraulic assemblies, confined spaces |
| Square Slot Screws | Square recess, reduced cam-out | Industrial assembly, electrical fittings, equipment panels |
| Torx Screw | Six-lobe recess, high torque transfer | Automotive, power tools, precision instruments, high-vibration joints |
| Set Screws | Headless, fully threaded, point contact | Shaft locking, collar and pulley retention, position adjustment |
| Hand Screw | Knurled or thumb head, tool-free tightening | Adjustment knobs, access panels, equipment covers, quick-release points |
| Tapping Screws | Self-tapping thread, sharp point | Sheet metal, plastics, light gauge enclosures, HVAC components |
| Rolling Screws | Thread-forming, no chip generation | Die-cast and plastic housings, sealed assemblies where debris is unacceptable |
| Drilling Screws | Drill point, self-drilling through metal | Steel framing, roofing, cladding, ductwork, single-operation metal fixing |
| Wood Screws | Coarse thread, countersunk or pan head | Furniture, joinery, timber structures, decking, packaging |
| Other Screws | Special heads, threads and materials | Drawing-based parts for rail, mining, agricultural and marine equipment |
Drive Selection: Matching the Recess to the Assembly Method
Drive format determines how torque is transferred, how fast the line can run and how much damage a misaligned driver can cause. We help customers match the recess to the tooling and the torque window before production starts.
- Slotted: universal flat-blade access, open groove acts as an informal torque limit on delicate materials.
- Phillips: self-centering cross recess speeds one-handed power-tool engagement; cam-out protects threads in high-volume automated assembly.
- Hexagon socket: internal hex transmits higher torque than surface drives and allows flush counterbored installation.
- Torx and square slot: larger contact area reduces driver slip and head damage in high-torque or high-vibration joints.
Materials, Thread Forms and Surface Finishing
We produce Stainless Steel Screws in carbon steel, stainless steel and low-alloy steel. Thread form is matched to the substrate: machine threads for pre-tapped holes, self-tapping threads for sheet metal and plastics, thread-forming profiles for die-cast housings, and coarse wood threads for timber. Strength grades for socket head products include 8.8, 10.9 and 12.9 where the application demands it.
Post-treatment options include zinc plating, nickel plating, blackening and hot-dip galvanizing. Our process diversity lets us handle complex geometries and mixed material batches without splitting the order across suppliers.
Standards We Manufacture To
Our screw catalogue covers the major international systems, so a single purchase order can carry parts to different regional standards without separate sourcing.
- DIN 84, DIN 85, DIN 963, DIN 964, DIN 427, DIN 965, DIN 966, DIN 967, DIN 7985, DIN 7984, DIN 7991, DIN 912, DIN 9841
- ISO 1207, ISO 7045, ISO 4762, DIN EN ISO 7380-1
- ASME/ANSI B18.6.2, B18.6.3, B18.6.7M, B18.3, ASME B18.10
- JIS B 1111 and equivalent JIS screw specifications
Where a project calls for a standard not listed here, we develop to the drawing or sample you provide.
Quality Control and Acceptance Testing
Total quality management runs through every production stage, with inspection after each process and 100% final inspection of finished goods against customer requirements and international standards. Our in-house laboratory is equipped with a spectrometer, coordinate measuring machine (CMM) and X-ray flaw detector, covering chemical composition, mechanical properties, non-destructive testing and geometric dimensions.
We hold ISO 9001 certification and manufacture to internationally recognised standards. Inspection records and dimensional reports are prepared to the acceptance criteria agreed for each order.
Customization, Packaging and Delivery Scope
Customized production is core to our business. Our engineering team develops screws from customer drawings or physical samples, covering special head forms, non-standard thread pitches, dedicated materials and specific surface finishes. We also supply standard parts from stock for maintenance and general assembly demand.
Packaging is configured for the sales channel: bulk cartons, retail blister packs, custom boxes and export cartons. We support small and bulk orders, with DDP delivery available to simplify inbound logistics. Our location within a two-hour drive of Shanghai and Ningbo ports keeps sea freight efficient, and air freight can be arranged for urgent requirements.
Information We Use to Configure Your Solution
To prepare an accurate screw specification and quotation, we work from the following project inputs. The more precisely these are defined, the faster we can confirm tooling, pricing and lead time.
- Head form and drive recess (slotted, Phillips, hex socket, square slot, Torx, or special)
- Nominal diameter, thread pitch and length, with tolerance class
- Thread type: machine, self-tapping, thread-forming, self-drilling or wood
- Material and strength grade (carbon steel, stainless steel, low-alloy steel; 8.8 / 10.9 / 12.9 where applicable)
- Surface finish and corrosion resistance requirement
- Applicable standard, or a drawing/sample for non-standard parts
- Substrate material and thickness at the joint
- Installation method and torque target
- Annual volume, batch size and delivery schedule
- Packaging format and labelling requirements
- Destination port and preferred trade term
