S-90729A267 M4 x 10 mm Stainless Steel Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction with passivated surface treatment
• Enhanced installation efficiency with 2.5mm hex drive that provides secure tool engagement and reduces stripping risk
• Reliable thread engagement through Class 6g tolerance coarse threading that accommodates minor misalignments
• Optimal flush mounting with undercut flat head design that sits perfectly countersunk in 100° angled applications
• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for heavy-duty fastening requirements
• Full-length fastening capability with complete threading that ensures maximum grip along the entire 10mm length
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These M4 metric flat head screws deliver critical performance advantages in demanding applications where corrosion resistance and mechanical reliability are paramount. The 316 stainless steel composition, enhanced by passivated finish, provides exceptional protection against chemical exposure and atmospheric corrosion in marine, chemical processing, and food industry applications. The undercut flat head profile ensures precise flush mounting while the hex drive design prevents cam-out during high-torque installation. With fully threaded coarse pitch configuration and Class 6g thread fit, these screws offer superior vibration resistance and installation consistency in machinery, equipment assembly, and structural frameworks where dimensional precision and long-term fastening integrity are essential.

Specification Summary & Compliance

This metric flat head screw features precise M4 x 0.7mm coarse thread with Class 6g tolerance and right-hand threading direction. The 8mm head diameter maintains tight tolerances (-0.127 to 0.127mm) while the 100° countersink angle ensures proper seating. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, guaranteeing environmental compliance for industrial distribution and use. The combination of 70,000 psi tensile strength and Rockwell B70 hardness validates mechanical performance for critical fastening applications.
