S-90269A219 M4 Shoulder Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 Stainless Steel construction, ideal for harsh industrial environments and chemical exposure
• Precise component alignment enabled by the 5mm shoulder diameter with tight tolerance control for reduced assembly errors
• High-strength performance delivering 70,000 psi tensile strength and 35,000 psi shear strength for demanding mechanical applications
• Secure, slip-resistant installation with knurled head texture and 2.5mm hex socket drive for reliable torque transmission
• Consistent thread engagement through Class 5g6g metric coarse threads (0.7mm pitch) ensuring vibration-resistant fastening
• Extended service life with Rockwell B79 hardness providing excellent wear resistance and durability
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial supply chain requirements

Professional Applications & Engineering Value

This M4 shoulder screw delivers critical engineering value in precision assemblies where component alignment and corrosion resistance are paramount. The 316 Stainless Steel construction provides exceptional performance in chemical processing, marine, and food-grade applications where moisture and corrosive agents degrade ordinary fasteners. The 9mm shoulder length with controlled tolerances acts as a precise locating dowel, eliminating component misalignment while the Class 5g6g thread fit ensures consistent clamping force in vibrating environments. The combination of hex socket drive and knurled head prevents tool slippage during installation in confined spaces, making these metric shoulder screws ideal for precision machinery, automation equipment, and optical instrument manufacturing where reliability cannot be compromised.

Specification Summary & Compliance

This precision shoulder screw features M4 x 0.7mm coarse metric thread with Class 5g6g tolerance per ISO standards. Shoulder diameter maintains -0.072 to -0.01 mm tolerance with shoulder length tolerance of 0 to 0.25 mm. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for industrial distribution and use.
