S-91210A836 M8 x 20 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with a 90° cone point that bites into materials for secure, permanent fastening in high-vibration environments
• Exceptional durability and corrosion resistance provided by the zinc-plated alloy steel construction and Rockwell C45 hardness rating
• Easy and secure installation with a 4mm hex drive that allows for high torque application without cam-out, ensuring a tight fit
• Reliable and consistent thread engagement due to the coarse thread spacing and Class 5g6g thread fit, which accommodates minor variations
• Space-saving headless design ideal for applications where a protruding fastener head is not permissible
• Guaranteed mechanical performance as it is manufactured to meet the stringent dimensional and quality requirements of DIN 914 and ISO 4027 standards
• Safe for use in regulated industries with full compliance to RoHS 3 and REACH environmental directives

Professional Applications & Engineering Value

This M8 set screw is engineered to solve critical challenges in industrial assembly and machinery. The zinc-plated alloy steel material provides a robust combination of strength and corrosion resistance, essential for components exposed to harsh operating conditions. Its headless design and 90° cone point are specifically valuable for securing collars, gears, and pulleys onto shafts, preventing axial movement without requiring additional space. The coarse metric thread and Class 5g6g thread fit ensure quick assembly and a reliable grip, even in materials where fine threads might strip. This makes it an indispensable industrial set screw for applications in automotive, manufacturing, and heavy equipment where vibration resistance and long-term reliability are non-negotiable.

Specification Summary & Compliance

This set screw features an M8 x 1.25mm coarse thread with a Class 5g6g thread fit as per ISO metric standards, ensuring precise dimensional accuracy. The manufacturing and quality are strictly controlled to conform to DIN 914 / ISO 4027 specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances and safe for industrial use.
