Product Description

Product Introduction:

Screws, akin to bolts, differ in application. They often don't need a nut, screwing into pre-drilled threaded holes or forming threads in softer materials via self-tapping for fastening, connecting, or positioning.

Product Features:

Screw Core Classifications:

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

Self-Tapping Screws: Drill, tap, and 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 with material, 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: Integrate 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 machine and self-tapping screws secure housings, circuit boards, components. Materials: stainless steel 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, and decor.

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

Precision Instruments & Watches: Miniature machine screws with top material and tolerance.

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