• Precise thread engagement with Class 5g6g fine pitch metric threads ensuring secure, vibration-resistant fastening in critical applications
• Space-saving headless design with 8mm hex drive for installations where clearance is limited and flush mounting is required
• Reliable performance standardization through DIN 916/ISO 4029 compliance, guaranteeing consistent quality and interchangeability
• Environmental responsibility with full RoHS 3 and REACH compliance, meeting strict international regulatory standards
• Optimized for fine adjustments with 1.5mm fine pitch threads providing greater control in precision assembly applications

Professional Applications & Engineering Value

This M16 set screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and precise component positioning are critical. The alloy steel construction with Rockwell C45 hardness provides the necessary strength to withstand cyclic loading without compromising thread integrity. The fine pitch metric thread (1.5mm) combined with Class 5g6g thread fit ensures minimal backlash and superior clamping force distribution, making it ideal for precision machinery, automotive assemblies, and industrial equipment where micrometer-level adjustments matter. The headless hex design with 8mm drive accommodates space-constrained applications while the cup tip creates permanent seating marks that resist loosening under extreme operational conditions.

Specification Summary & Compliance

This metric set screw features precise Class 5g6g thread fit tolerance according to ISO standards, ensuring consistent performance across applications. Manufacturing strictly adheres to DIN 916 and ISO 4029 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances. The right-hand fine pitch thread (M16 x 1.5mm) and 16mm length provide standardized mounting solutions for industrial equipment requiring reliable, high-strength fastening components.
