Product Description

Product Introduction:

Screws, similar to bolts, have distinct applications. They often don't require a nut, as they screw into pre-threaded holes or form threads in softer materials via self-tapping, for fastening, connecting, or positioning.

Product Features:

Screw Core Classifications:

Machine Screws: Standard threads (metric, imperial) for threaded holes. Shank can be fully or partially threaded, ideal for precision.

Self-Tapping Screws: Drill, tap, 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.

Key Characteristics:

Distinct characteristics compared to bolts:

Primarily "tapping" or "screwing": Form threaded fit, 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: Functions like drilling, tapping, locking, sealing.

Requirements on Substrate: Load-bearing depends on substrate strength (plastics, wood, metal).

Typical Application Areas:

Screws are ubiquitous, spanning almost all industrial and daily life sectors:

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

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

Construction & Decoration:

Drywall Screws: Connect drywall to joists.

Structural Screws: Connect light steel and wood structures.

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

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

Furniture & Wood: Connects wood and particleboard with wood screws.

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

Aerospace: Titanium or non-alloy screws, lightweight and corrosion-resistant.
