Professional Applications & Engineering Value

This precision M2.5 set screw delivers exceptional engineering value in applications requiring reliable shaft positioning and component retention. The 303 stainless steel material provides excellent corrosion resistance for harsh environments, while the ultra-fine 0.2 mm pitch thread ensures maximum contact surface area for superior holding power against vibration and rotational forces. The hex headless design with 1.5 mm drive accommodates space-constrained assemblies, particularly in precision instruments, machinery, and electronic enclosures where flush mounting is critical. The alloy steel ball tip creates consistent point contact, reducing surface deformation on shafts and gears while maintaining secure positioning. This combination of metric threading, material durability, and precision manufacturing makes it ideal for high-performance industrial fastening applications demanding repeatable accuracy.

Specification Summary & Compliance

This metric fastener features Class 6g thread tolerance according to ISO standards, ensuring precise dimensional accuracy and interchangeability. The M2.5 x 0.2 mm ultra-fine thread with right-hand direction provides optimal engagement characteristics. Manufacturing compliance includes RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloy and full REACH (EC 1907/2006) compliance, meeting current environmental regulations for industrial components.
