Product Description

Product Introduction:

Screws differ from bolts by not needing a nut. They screw into pre-drilled threaded holes or form threads in softer materials like plastic or wood, used for fastening, connecting, or positioning.

Product Features:

Screw Core Classifications:

Machine Screws: Standard threads for pre-machined holes. Shank can be fully or partially threaded, ideal for precision assembly.

Self-Tapping Screws: Drill, tap, and push without pre-drilled holes.

Ordinary Self-Tapping Screws: For plastics, wood, thin metal sheets.

Self-Drilling Screws: Drill tip penetrates steel, eliminates pre-drilling, boosts efficiency.

Wood Screws: Deep threads, large pitch, sharp teeth for wood, ensuring strong lock.

Set Screws: Fix positions, prevent slippage or rotation. Various end shapes:

Tapered End: High locking force for hard surfaces.

Flat End: Large contact area, non-damaging.

Concave/Cylindrical End: For positioning in shaft holes.

Structural screws: High-strength, replace bolts in steel structures, speeding installation.

Key Characteristics:

Distinct characteristics compared to bolts:

Primarily "tapping" or "screwing": Form threaded fit, avoiding nuts.

Frequent Disassembly: Secure covers, panels, requiring assembly/disassembly.

Wide Size Range: From precision eyewear screws to large self-tapping screws.

High Functional Integration: Functions like drilling, tapping, locking, sealing.

Substrate Requirements: Load-bearing depends on substrate strength.

Typical Application Areas:

Screws span almost all industrial and daily life sectors:

Electronics/Appliances: Miniature screws for housings, circuit boards, components.

Machinery & Automation: Mounting panels, covers, sensors with hexagonal or pan head screws.

Construction & Decoration:

Drywall Screws: Connect drywall to joists.

Structural Screws: Connect steel and wood structures.

Self-Drilling Screws: Secure color steel plates to purlins.

Automotive: Self-tapping and special screws for interiors, wiring, electronics, decor.

Furniture & Wood: Wood screws connect wood and particleboard.

Precision Instruments & Watches: Miniature screws with high material standards.

Aerospace: Lightweight, corrosion-resistant titanium or non-alloy high-strength screws.
