S-91217A011 M2 x 3 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 extended service life
• Exceptional holding power provided by the 90° cone point, which bites into the mating surface for a secure, vibration-resistant lock
• Reliable mechanical strength with a Rockwell B80 hardness rating, ensuring the screw maintains its form under load
• Precise and secure fastening guaranteed by the Class 6g thread fit, offering optimal assembly tolerance
• Streamlined installation in confined spaces due to the headless design and compact 3mm length
• Easy installation and high torque application enabled by the internal hex socket (0.9mm drive)
• Global compliance and safety with adherence to RoHS 3 and REACH regulations, ensuring environmental and health standards are met

Professional Applications & Engineering Value

This M2 hex socket set screw is engineered to solve critical challenges in precision assembly. Manufactured from durable 18-8 stainless steel, it provides excellent resistance to rust and corrosion, making it a reliable choice for machinery, electronics, and automotive components exposed to moisture or chemicals. The headless design and compact 3mm length allow for flush mounting in tight spaces where protrusions are not permissible. The 90° cone point is specifically designed to create a strong, permanent lock by embedding into the shaft, effectively preventing axial movement and loosening from vibrations—a common failure point in dynamic industrial applications. Its compliance with DIN 914 / ISO 4027 standards ensures interchangeability and reliability in global engineering projects.

Specification Summary & Compliance

This metric set screw features an M2 x 0.4mm coarse thread with a Class 6g tolerance for precise fit. It is manufactured to meet the dimensional and mechanical specifications of DIN 914 and ISO 4027. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and safe for use in regulated industries.
