S-91287A055 M4 x 45 mm ISO 4017, DIN 933 18-8 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and outdoor applications
• High tensile strength of 100,000 psi ensures reliable performance under heavy loads and vibration, reducing failure risks
• Coarse thread design with 0.7mm pitch provides faster installation and superior grip in soft materials or where frequent disassembly isn't required
• Fully threaded shank offers consistent clamping force along the entire 45mm length for uniform stress distribution
• External hex drive with 7mm head width enables easy installation with standard tools, reducing assembly time and labor costs
• Precision Class 6g thread fit guarantees consistent engagement and compatibility with standard metric nuts and tapped holes
• Compliance with ISO 4017/DIN 933 standards ensures interchangeability and reliability in global engineering applications

Professional Applications & Engineering Value

These M4 hex head screws deliver critical engineering value through their 18-8 stainless steel composition and fully threaded coarse thread design. The combination addresses common industrial challenges including corrosion-induced fastener degradation in chemical processing, marine, and food equipment applications. The external hex drive provides superior torque transmission compared to internal drive types, preventing tool slippage during high-torque assembly in automotive frame construction or machinery manufacturing. With 100,000 psi tensile strength, these metric screws maintain joint integrity in vibrating environments where inferior fasteners might loosen over time. The 45mm length and Class 6g thread fit ensure precise engagement in structural assemblies while the coarse thread pitch resists cross-threading during rapid production line installation.

Specification Summary & Compliance

This M4 x 0.7mm x 45mm hex head screw features precision Class 6g thread tolerance per metric standards with fully threaded right-hand threading. Manufacturing complies with ISO 4017/DIN 933 specifications for dimensional accuracy and mechanical properties. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives, ensuring suitability for regulated industries and international supply chains.
