Product Overview

Self-Tapping Screw Types

Ordinary self-tapping screws: Feature 'wide thread' design with mostly plated surfaces
Self-cutting tapping screws: Include various head types (pan head, countersunk head, raised countersunk head, hexagonal head)
Self-extruding tapping screws: Typically use machine thread with triangular cross-section design
Self-drilling tapping screws: Designed for direct drilling into materials without pre-drilling
Wallboard tapping screws: Feature trumpet head design with phosphated surface treatment
Combination self-tapping screws: Integrated with washers for enhanced fastening performance

Key Features

Manufactured from carburized steel for superior strength
Heat-treated for optimal mechanical properties (carburizing for carbon steel, solution hardening for stainless steel)
High surface hardness with tough core ("soft outside steel" characteristic)
Surface protection through plating or phosphating treatments
Produced using high-speed cold heading process for consistent quality

Grade 8.8 Bolt Characteristics

Class 8.8 bolts offer superior strength compared to class 4.8 bolts, with greater tensile strength and torque tolerance. These high-reliability fasteners are ideal for heavy-load applications including bridge construction and large machinery assembly.

Blackening Treatment Benefits

Enhanced rust prevention: Iron tetraoxide film inhibits red rust formation
Durable surface: Chemical conversion process creates long-lasting protection
Improved lubrication: Porous surface retains anti-rust oils for better sliding properties
Non-flaking: Unlike plating, the treatment won't peel off over time
