S-91217A055 M3 x 4 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and reducing maintenance costs.
• Exceptional holding power from the 90° cone point design, which bites into materials to prevent component slippage and loosening.
• High-strength durability with a Rockwell B80 hardness rating, ensuring the screw withstands high torque and repeated adjustments without stripping.
• Precise and reliable fit due to the Class 6g thread tolerance, providing consistent performance and ease of assembly in metric applications.
• Secure, flush installation with a headless and hex drive design, allowing for a clean finish and access in confined spaces with a standard 1.5mm hex key.
• Broad industrial compliance meeting DIN 914/ISO 4027 standards, along with RoHS 3 and REACH regulations, ensuring safety and environmental responsibility.
• Optimized for coarse threading (M3 x 0.5mm), enabling quicker installation and robust performance in a wide range of materials.

Professional Applications & Engineering Value

This M3 set screw is engineered to address critical challenges in precision assembly, where vibration resistance and secure positioning are paramount. The 18-8 stainless steel material offers excellent corrosion resistance, making it suitable for applications in electronics, automotive, and machinery exposed to moisture or chemicals. The hex headless and cone point design ensures a flush mount while the pointed tip provides superior grip on shafts, gears, and collars, preventing axial movement under dynamic loads. With a Class 6g thread fit and coarse metric thread, it delivers reliable engagement and ease of use in high-volume production environments, reducing installation time and improving overall assembly integrity.

Specification Summary & Compliance

This set screw features a Class 6g thread fit for precise metric tolerances, conforming to DIN 914 and ISO 4027 manufacturing standards. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and safe for industrial use.
