Professional Applications & Engineering Value

This M3 ultra fine pitch set screw delivers exceptional engineering value in precision assembly applications where vibration resistance and space constraints are critical concerns. The 303 stainless steel construction provides excellent corrosion resistance for demanding environments, while the Class 6g thread fit ensures precise engagement and reliable performance in automated assembly systems. The alloy steel ball tip creates concentrated contact pressure that prevents component slippage in shaft collars, gears, and pulleys. The headless design with 1.5mm hex drive allows for flush mounting in compact assemblies while providing positive torque control. These metric set screws are particularly valuable in precision instruments, optical equipment, and electronic enclosures where ultra fine thread spacing prevents loosening under cyclic loading conditions.

Specification Summary & Compliance

This precision metric set screw features M3x0.25mm ultra fine threads with Class 6g thread fit per ISO metric standards, ensuring dimensional accuracy and proper engagement. The 15mm length provides optimal fastening depth for various applications. Manufacturing complies with RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and REACH (EC 1907/2006) compliance as of 06/14/2023. The right-hand thread direction and ball tip configuration meet industry standards for set screw applications requiring maximum holding power and reliability.
