Product Description

Product Introduction:

Screws are fasteners like bolts but for different uses. They typically do not need a nut and directly screw into pre-threaded holes or create threads in softer materials, achieving fastening, connecting, or positioning.

Product Features:

Screw Core Classifications:

Machine Screws: With standard threads (e.g., metric, imperial) for pre-threaded holes. Shanks can be fully or partially threaded for precision assembly.

Self-Tapping Screws: Drill, tap, and push without pre-threading. Subcategories:

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

Self-Drilling Self-Tapping Screws: Drill tips to penetrate steel, no pre-drilling needed, boosting efficiency.

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

Set Screws: Fix positions, prevent slippage with varied end shapes:

Tapered End: High locking force, ideal for hard surfaces.

Flat End: Large contact, surface-safe.

Concave/Cylindrical End: For shaft hole positioning or pressing.

Structural Screws: High-strength self-tapping screws, heat-treated, replace bolts in steel structures for faster installation.

Key Characteristics:

Screws vs. Bolts:

"Tapping" or "Screwing": Direct threaded fit with connected material, no nut needed.

Frequent Disassembly: Used for covers, panels, requiring frequent assembly/disassembly.

Wide Size Range: From tiny precision screws in eyeglasses to large self-tapping screws in buildings.

Functional Integration: Combine functions like drilling, tapping, locking, sealing (e.g., screws with washers).

Substrate Requirements: Load capacity depends on substrate strength (e.g., plastics, wood, metal).

Typical Application Areas:

Screws are everywhere, spanning industrial and daily use:

Electronics and Appliances: Miniature machine and self-tapping screws secure housings, boards, components. Materials: stainless steel or treated carbon steel.

Machinery & Automation: Ideal for mounting panels, covers, sensors, guide rails, clamps using primarily hexagonal or pan head screws.

Construction & Decoration:

Drywall Screws: Perfect for connecting drywall to joists.

Structural Screws: Connects light steel and wood structures effectively.

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

Automotive Industry: Widely uses self-tapping screws and special screws in car interiors, wiring, electronics, and decor.

Furniture & Wood Products: Wood screws are essential for connecting wood and particleboard.

Precision Instruments & Watches: Uses precise miniature screws, demanding high material and tolerance standards.

Aerospace: Utilizes high-strength, lightweight, corrosion-resistant titanium alloy or non-alloy special screws.
