S-91217A310 M8 x 12 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 industrial environments
• Maximum holding power provided by the 90° cone point design that bites securely into mating materials
• Reliable installation and removal through the 4mm hex drive, preventing tool slippage and damage
• Precise thread engagement with Class 6g fit and coarse 1.25mm pitch for quick assembly and vibration resistance
• Exceptional mechanical strength from Rockwell B80 hardness, ensuring long-term performance under load
• Space-saving headless design allowing for flush mounting in confined applications
• Full regulatory compliance meeting international DIN 914/ISO 4027 standards and environmental regulations

Professional Applications & Engineering Value

This M8 set screw delivers critical engineering solutions where permanent positioning and alignment are paramount. The 18-8 stainless steel material provides excellent corrosion resistance for machinery exposed to moisture, chemicals, or outdoor elements. The 90° cone point creates concentrated pressure that prevents component slippage in high-vibration applications such as motor mounts, gear assemblies, and precision equipment. With its headless design and hex drive, it offers flush installation where protruding fasteners are unacceptable. The coarse thread with Class 6g fit ensures rapid assembly while maintaining secure engagement in soft metals and plastics, making it versatile across automotive, manufacturing, and electronic enclosure applications.

Specification Summary & Compliance

This metric set screw features M8 x 1.25mm coarse threading with Class 6g tolerance for precise fit. Manufactured to DIN 914/ISO 4027 specifications with 90° cone point geometry and 12mm length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries.
