• Precise and reliable thread engagement with Class 6g thread fit, ensuring consistent performance in metric assemblies.
• Space-saving headless design allows for flush mounting in applications where protrusions are not permissible.
• Easy installation with standard tools using the 1.5 mm hex drive, facilitating quick and efficient assembly processes.
• Compliance with international safety and environmental standards including RoHS 3 and REACH, ensuring safe use in regulated industries.

Professional Applications & Engineering Value

These M3 x 0.5 mm DIN 914 set screws are engineered to address critical challenges in precision assemblies, such as securing gears, pulleys, and collars on shafts without head interference. The 18-8 stainless steel offers excellent resistance to oxidation and chemical exposure, making these headless screws suitable for automotive, aerospace, and machinery applications where reliability is paramount. The 120° cone point and coarse thread pitch provide maximum grip and prevent loosening under dynamic loads, while the hex drive ensures high torque transmission without cam-out. By meeting DIN 914/ISO 4027 standards, these metric set screws deliver consistent dimensional accuracy and performance, reducing assembly errors and maintenance needs in industrial settings.
