Thread Size: #4 (2.9mm); Thread Length: 1 inch (25mm) Head Diameter: 0.21 inch (5.3mm); Head Height: 0.09 inch (2.3mm); Torx Drive T10 Material: 304 stainless steel (A2) and no exterior finish, greater strength and corrosion resistance performance than regular stainless steel or zinc plated fasteners; can withstand harsh weather, moisture, and chemicals, ideal for outdoor, marine, or industrial environments Key features: 1) High torque resistance, the torx drive design provide superior torque transfer; 2) Self tapping efficiency; 3)Wide material compatibility, suitable for a variety of materials, like sheet metal, plastic, and composite boards Wide Applications: automotive assembly; electronics enclosures; DIY furniture projects; outdoor equipments; HVAC systems; roofing projects; Their self-tapping tip eliminates pre-drilling, saving time on jobsites or DIY renovations Material Advantage
Engineered from premium 304 stainless steel (A2/18-8 grade), these fasteners feature a chromium-nickel alloy composition that delivers superior corrosion resistance and mechanical strength compared to standard stainless grades or zinc-plated alternatives. The material's inherent 18% chromium and 8% nickel content forms a passive oxide layer, eliminating the need for secondary coatings while providing exceptional protection against salt spray, chemical exposure, and atmospheric corrosion. This marine-grade stainless construction ensures reliable performance in demanding environments, including coastal installations, industrial facilities, and outdoor applications where moisture resistance and structural integrity are critical.
