S-91390A705 M5 x 14 mm DIN 916 Set Screws

Key Features & Benefits at a Glance

• Maximum holding power with Class 5g6g thread fit ensuring precise engagement and vibration resistance in demanding applications
• Superior durability thanks to alloy steel construction and Rockwell C45 hardness, providing excellent wear resistance and long service life
• Secure installation enabled by the 2.5mm hex drive design that prevents cam-out and allows high torque application
• Enhanced gripping capability through the cup tip design that creates positive seating and prevents component slippage
• Reliable coarse threading (M5x0.8mm) that facilitates quicker installation and better performance in softer materials
• Space-saving headless design that allows flush mounting where clearance is limited
• Global compliance assurance with DIN 916 standards and environmental regulations for worry-free international sourcing

Professional Applications & Engineering Value

This high-strength alloy steel set screw delivers exceptional engineering value in precision assembly applications where reliable component positioning is critical. The headless design with hex drive provides optimal space utilization while maintaining accessibility for installation and removal. Engineered with Class 5g6g thread fit and coarse metric threading (M5x0.8mm), this fastener ensures rapid assembly and superior resistance to vibrational loosening in machinery, automotive components, and industrial equipment. The cup tip configuration creates concentrated contact pressure, preventing shaft movement in pulleys, gears, and collars. With Rockwell C45 hardness, this set screw maintains its mechanical properties under heavy static and dynamic loads, making it ideal for permanent or semi-permanent fastening solutions across manufacturing, automation, and heavy equipment sectors.

Specification Summary & Compliance

This metric set screw features precise M5x0.8mm coarse threading with Class 5g6g tolerance according to DIN 916 specifications, ensuring dimensional accuracy and reliable performance. The 14mm length and 2.5mm hex drive provide consistent installation characteristics. Manufacturing complies with DIN 916 standards for dimensional and mechanical properties. Environmental compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances for global industrial applications.
