S-90358A121 M3.5 x 6 mm Alloy Steel Ultra-Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional strength-to-size ratio with 140,000 psi tensile strength, ideal for high-stress applications
• Corrosion-resistant black-oxide finish on alloy steel for enhanced durability in demanding environments
• Ultra-low profile head design (1mm height) saves space in compact assemblies
• Precision Class 5g6g thread fit ensures reliable engagement and vibration resistance
• 2mm hex drive compatibility provides secure tool engagement with standard industrial drivers
• Rockwell C32 hardness maintains thread integrity through repeated installation cycles
• Full threading (M3.5 x 0.6mm) offers maximum grip length for superior holding power

Professional Applications & Engineering Value

These black-oxide alloy steel socket head cap screws solve critical space and performance challenges in precision engineering. The ultra-low profile design with 6mm head diameter enables flush mounting in confined spaces where standard fasteners won't fit. The M3.5 metric coarse thread (0.6mm pitch) with Class 5g6g precision ensures rapid assembly while maintaining vibration resistance in machinery, automotive components, and electronic enclosures. The combination of 140,000 psi tensile strength and Rockwell C32 hardness provides reliable performance in high-vibration industrial applications where fastener failure is not an option. The fully threaded right-hand design offers maximum clamping force distribution across the entire 6mm length.
