Key Features & Benefits at a Glance
- Superior holding power with hardened alloy steel construction and Rockwell C45 hardness for reliable, long-term fastening in demanding environments.
- Precise installation and high torque application enabled by the 1.3mm internal hex drive, providing a secure grip for assembly tools.
- Excellent resistance to loosening under vibration due to the coarse 0.45mm thread pitch, ensuring a stable and secure connection.
- Consistent and reliable thread engagement guaranteed by the Class 5g6g thread fit, meeting stringent dimensional standards.
- Secure fastening with minimal protrusion thanks to the headless and flat tip design, ideal for compact assemblies and flush mounting.
- Guaranteed material integrity and performance from compliance with DIN 913/ISO 4026 specifications for dimensional accuracy and mechanical properties.
- Safe for use in regulated industries as it is fully compliant with RoHS 3 and REACH environmental regulations.
Professional Applications & Engineering Value
This M2.5 set screw is engineered to address critical challenges in precision assembly and machinery. The alloy steel material, hardened to a Rockwell C45 hardness, provides exceptional shear strength and wear resistance, preventing failure in high-stress applications like motor shafts, gears, and precision instruments. The headless design and flat tip allow for a flush finish, eliminating interference in tight spaces. The coarse metric thread with a 0.45mm pitch ensures quick assembly and superior resistance to vibrational loosening, a common issue in dynamic industrial equipment. Paired with the 1.3mm hex drive for secure tool engagement, this screw delivers reliable, repeatable clamping force for set screw applications demanding exact positioning and security.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards with a Class 5g6g thread fit per ISO metric specifications, ensuring accurate and consistent threading. It is manufactured to meet the mechanical and dimensional requirements of DIN 913 and ISO 4026. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of hazardous substances and safe for industrial use.
