S-90251A309 M4 x 10 mm DIN 916, ISO 4029 Set Screws

Key Features & Benefits at a Glance

• Permanent vibration resistance with nylon patch locking that maintains integrity across -50° to 250°F temperature cycles
• Superior corrosion resistance through 18-8 stainless steel construction for extended service life in harsh environments
• Precision thread engagement with Class 6g fit ensuring reliable fastening and consistent clamping force
• Secure installation and removal via 2mm hex socket drive that prevents tool slippage and damage
• Effective material penetration from cup point design that digs into shafts for positive positioning
• Industry-standard compatibility with DIN 916/ISO 4029 specifications for reliable interchangeability
• Enhanced mechanical strength from Rockwell B80 hardness that resists deformation under load

Professional Applications & Engineering Value

This M4 set screw with nylon patch locking technology solves critical vibration-induced loosening in industrial machinery, automotive assemblies, and precision equipment. The 18-8 stainless steel construction provides exceptional corrosion resistance while maintaining Rockwell B80 hardness for durability. The cup point tip creates positive engagement with mating surfaces, preventing component slippage in high-torque applications. With Class 6g thread fit and coarse 0.7mm pitch, these hex socket set screws deliver reliable performance in demanding environments where thermal cycling and chemical exposure would compromise inferior fasteners.
