S-91210A834 M8 x 16 mm DIN 914, ISO 4027 Set Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated alloy steel construction for extended service life in harsh industrial environments
• Exceptional holding power provided by the 90° cone point design that creates deep penetration and prevents component slippage
• Optimized thread engagement with Class 5g6g thread fit ensuring precise, secure fastening in coarse thread applications
• High-strength performance backed by Rockwell C45 hardness rating for reliable operation under mechanical stress
• Space-saving installation through headless design with 4mm hex drive for applications with limited clearance
• Global compliance assurance meeting DIN 914/ISO 4027 standards with RoHS 3 and REACH environmental regulations
• Quick installation and removal facilitated by standard right-hand metric threading and hex drive compatibility

Professional Applications & Engineering Value

This M8 set screw delivers critical engineering solutions for industrial applications requiring secure component positioning. The zinc-plated alloy steel construction provides essential corrosion protection while maintaining the Rockwell C45 hardness needed for high-stress environments. The 90° cone point design ensures maximum gripping force by concentrating pressure on a small surface area, preventing rotational movement in pulleys, gears, and collars. As a headless screw with hex drive configuration, it offers flush mounting in confined spaces where protruding fastener heads would interfere with machinery operation. The coarse thread with 1.25mm pitch provides rapid installation and superior resistance to vibration loosening in dynamic industrial equipment.

Specification Summary & Compliance

This metric set screw features M8 x 1.25mm coarse threading with Class 5g6g thread fit tolerance per ISO standards. Manufactured to DIN 914 and ISO 4027 specifications, the fastener ensures dimensional accuracy and interoperability. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, containing no restricted substances above threshold limits. The zinc-plated surface treatment provides additional corrosion protection while the alloy steel material with Rockwell C45 hardness meets mechanical performance requirements for industrial fastening applications.
