Product Description

Product Introduction:

Screws, unlike bolts, may not need a nut. They screw into pre-drilled holes or form threads in softer materials, ideal for fastening, connecting, or positioning.

Product Features:

Screw Core Classifications:

Machine Screws: Standard mechanical threads for threaded holes. Fully or partially threaded, perfect for precision assembly.

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

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

Self-Drilling Self-Tapping Screws: Drill tip penetrates steel, eliminating pre-drilling, boosting efficiency.

Wood Screws: Deep threads, large pitch, sharp teeth for wood, offering strong locking force.

Set Screws: Fix positions, prevent slippage. End shapes include:

Tapered End: High locking force, for hard surfaces.

Flat End: Large contact, non-damaging.

Concave/Cylindrical End: Positioning or pressing into shaft holes.

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

Key Characteristics:

Distinct from bolts:

Primarily "tapping" or "screwing": Threaded fit with material, avoiding nuts.

Frequent Disassembly: Secure covers, panels, enabling 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.

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

Typical Application Areas:

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

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

Machinery & Automation: Mount panels, covers, sensors, guide rails, clamps with hex 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: Wood screws connect wood and boards like particleboard.

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

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