Polishing Treatment Oxidation Treatment High-Quality Countersunk Hex Machine Screw - Polishing and Oxidation Treatment

Product Description

Product Introduction:

Screws, akin to bolts, differ in application. Often used without a nut, they screw into pre-drilled threaded holes or form threads in softer materials via self-tapping, serving for fastening, connecting, or positioning.

Product Features:

Screw Core Classifications:

Machine Screws: Standard mechanical threads for pre-machined holes, ideal for precision assembly.

Self-Tapping Screws: Drill, tap, push without pre-drilled holes. Types include:

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

Self-Drilling Self-Tapping Screws: Drill tip penetrates steel, no pre-drilling needed.

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

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

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, speed installation in steel structures.

Key Characteristics:

Distinct characteristics compared to bolts:

Primarily "tapping" or "screwing": Form threaded fit, avoid nuts.

Relatively Frequent Disassembly: Secure covers, panels, needing assembly/disassembly.

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

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

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

Typical Application Areas:

Screws are ubiquitous in almost all industrial and daily sectors:

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

Machinery & Automation: Mount panels, covers, sensors, 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 secure wood and particleboard effectively.

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

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