S-91210A814 M5 x 25 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated alloy steel construction, extending service life in demanding industrial environments.
• Exceptional holding power provided by the 90° cone point design, which bites into surfaces to prevent component slippage and loosening.
• High-strength durability backed by a Rockwell C45 hardness rating, ensuring reliable performance under high stress and vibration.
• Secure and efficient installation with a 2.5 mm hex drive, allowing for high torque application in confined, headless designs.
• Precise and reliable threading with a Class 5g6g thread fit and coarse M5x0.8 mm pitch for quick assembly and consistent engagement.
• Broad compatibility through compliance with DIN 914 and ISO 4027 standards, ensuring interchangeability and quality in global applications.
• Environmentally responsible manufacturing with RoHS 3 and REACH compliance, meeting stringent international regulatory requirements.

Professional Applications & Engineering Value

This M5 set screw is engineered to address critical challenges in precision assembly and machinery. The zinc-plated alloy steel material provides a robust barrier against rust and wear, essential for maintaining integrity in humid or corrosive industrial settings. Its headless design and hex drive enable flush mounting and high-torque fastening in tight spaces, preventing protrusions that could interfere with moving parts. The 90° cone point and coarse thread spacing ensure a firm grip on shafts and collars, resisting rotational forces and vibration-induced loosening in applications like motor mounts, gear assemblies, and precision tooling. By conforming to DIN 914 and ISO 4027 standards, it guarantees dimensional accuracy and reliability, reducing downtime and maintenance costs in industrial set screw applications.
