Product Description

Product Introduction:

Screws, unlike bolts, skip nuts, screwing into pre-threaded holes or self-tapping in softer materials for fastening, connecting, or positioning.

Product Features:

Screw Core Classifications:

Machine Screws: Standard threads for pre-machined holes. Threaded shank for precise assembly.

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

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

Self-Drilling Self-Tapping Screws: Drill tip penetrates steel, cutting pre-drilling time.

Wood Screws: Deep threads, sharp teeth for wood, ensuring strong locking force.

Set Screws: Fix positions, stop slippage/rotation with varied end shapes:

Tapered End: High locking force for hard surfaces.

Flat End: Large contact area without damage.

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

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

Key Characteristics:

Distinct from bolts:

"Tapping"/"screwing": Form fit with material, skipping nuts.

Frequent Disassembly: Secure covers/panels for easy assembly/disassembly.

Wide Size Range: From eyewear precision screws to large self-tappers in structures.

High Functional Integration: Combine drilling, tapping, locking, sealing.

Substrate Needs: Load-bearing relies on substrate strength (plastics, wood, metal).

Typical Application Areas:

Screws are integral, spanning almost all industrial and daily sectors:

Electronics/Appliances: Miniature screws for housings, boards, components. Materials: stainless or carbon steel.

Machinery & Automation: Mount panels, covers, sensors with hex/pan head screws.

Construction & Decoration:

Drywall Screws: Connect drywall to joists.

Structural Screws: Join light steel and wood structures.

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

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

Furniture & Wood: Wood screws join wood and boards like particleboard.

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

Aerospace: High-strength, lightweight, corrosion-resistant titanium screws.
