• Secure component positioning through flat tip design that distributes clamping force evenly without damaging mating surfaces
• Industry-standard compatibility with coarse 1.25mm pitch threads meeting DIN 913/ISO 4026 specifications for global interchangeability
• Environmental compliance assurance with RoHS 3 and REACH regulations, making them suitable for regulated industrial sectors
• Right-hand thread configuration providing familiar installation for standard assembly procedures and maintenance operations

Professional Applications & Engineering Value

This M8 set screw delivers critical engineering solutions where space constraints and vibration resistance are paramount. The alloy steel composition with Rockwell C45 hardness ensures the fastener maintains its clamping force under continuous stress, preventing loosening in machinery, automotive assemblies, and precision equipment. The headless design with 4mm hex drive enables completely flush installation, ideal for rotating components where protruding fasteners would cause interference. The coarse 1.25mm pitch threads with Class 5g6g precision provide quicker installation and superior resistance to vibrational loosening compared to fine-pitch alternatives. These metric set screws are particularly valuable in manufacturing jigs, gear assemblies, and coupling applications where reliable positioning and repeated adjustability are required without compromising structural integrity.

Specification Summary & Compliance

This M8 x 1.25mm x 55mm set screw maintains Class 5g6g thread tolerance per ISO metric standards, ensuring precise fit and consistent performance. Manufacturing conforms to DIN 913 ISO 4026 specifications for dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for global industrial supply chains with stringent environmental requirements.
