S-91210A435 M8 x 22 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with 90° cone point design that bites into mating surfaces for maximum resistance to loosening under vibration and load
• Exceptional durability achieved through Rockwell C45 hardness rating, providing excellent wear resistance and long service life in demanding applications
• Precise thread engagement with Class 5g6g thread fit ensuring consistent performance and reliable fastening in metric assemblies
• Optimized installation efficiency through 4mm hex drive design that allows high torque application in confined spaces where headless configuration is required
• Reliable coarse threading with 1.25mm pitch that resists cross-threading and enables quicker installation compared to fine thread alternatives
• Industry-standard compliance meeting DIN 914 and ISO 4027 specifications, ensuring interchangeability and quality assurance across global applications
• Environmental responsibility with RoHS 3 and REACH compliance, making these set screws suitable for regulated industries and international markets

Professional Applications & Engineering Value

This M8 set screw delivers exceptional engineering value in applications requiring secure positioning of components on shafts, axles, and within assemblies. The alloy steel construction, combined with Rockwell C45 hardness, provides the necessary strength to prevent deformation under high clamping forces. The 90° cone point creates concentrated pressure points that dig into mating surfaces, solving common issues of component slippage in rotating equipment. The headless design with 4mm hex drive allows installation in space-constrained applications where protruding fastener heads would interfere with adjacent components. With coarse 1.25mm thread pitch and Class 5g6g thread fit, these metric set screws offer reliable performance in industrial machinery, automotive systems, and precision equipment where vibration resistance and positional accuracy are critical.

Specification Summary & Compliance

This precision metric set screw features M8 x 1.25mm coarse threading with Class 5g6g thread fit tolerance, ensuring dimensional accuracy per international standards. The 22mm length and cone point configuration comply with DIN 914 and ISO 4027 manufacturing specifications. The product meets critical regulatory requirements including RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) compliance for chemical safety, making it suitable for global industrial applications and environmentally conscious manufacturing operations.
