| Product Introduction | Screws, akin to bolts, differ in application. They often don't need a nut, instead screwing into pre-drilled threaded holes or forming threads in softer materials via self-tapping, for fastening, connecting, or positioning. |
|---|
| Machine Screws | Standard mechanical threads (metric, imperial) for pre-machined threaded holes. Shank can be fully or partially threaded, ideal for precision assembly. |
|---|
| Self-Tapping Screws | Drill, tap, and push without pre-drilled holes. Subcategories include: |
|---|
| Ordinary Self-Tapping Screws | Used for plastics, wood, thin metal sheets. |
|---|
| Self-Drilling Self-Tapping Screws | Drill tip penetrates steel plates, eliminating pre-drilling, boosting efficiency. |
|---|
| Wood Screws | Deep threads, large pitch, sharp teeth for wood, providing strong locking force. |
|---|
| Set Screws | Fix part positions, preventing slippage or rotation. Various end shapes: |
|---|
| Tapered End | High locking force, suitable for hard surfaces. |
|---|
| Flat End | Large contact area, non-damaging. |
|---|
| Concave/Cylindrical End | For positioning or pressing into shaft holes. |
|---|
| Structural screws | High-strength, heat-treated, replace bolts in steel structures, speeding up installation. |
|---|
| Primarily "tapping" or "screwing" | Form threaded fit with material, avoiding nuts. |
|---|
| Relatively Frequent Disassembly | Secure covers, panels, requiring assembly/disassembly. |
|---|
| Wide Size Range | From precision screws in eyewear to large self-tapping screws in structures. |
|---|
| High Functional Integration | Integrate functions like drilling, tapping, locking, sealing. |
|---|
| Requirements on Substrate | Load-bearing depends on substrate strength (plastics, wood, metal). |
|---|
| Electronics and Appliances | Miniature machine and self-tapping screws secure housings, circuit boards, components. Materials: stainless steel or treated carbon steel. |
|---|
| Machinery & Automation | Mounting panels, covers, sensors, guide rails, clamps with hexagonal or pan head screws. |
|---|
| Drywall Screws | Connect drywall to joists. |
|---|
| Self-Drilling Screws | Secure color steel plates and purlins. |
|---|
| Automotive | Various self-tapping and special screws for interiors, wiring, electronics, and decor. |
|---|
| Furniture & Wood | Wood screws connect wood and boards like particleboard. |
|---|
| Precision Instruments & Watches | Miniature machine screws with high material and tolerance standards. |
|---|
| Aerospace | High-strength, lightweight, corrosion-resistant titanium or non-alloy screws. |
|---|
| Main products | bolts, nuts, screws, washers, threaded rods, and non-standard items. |
