S-93245A633 M2.5 x 5 mm DIN 913, ISO 4026 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with alloy steel construction and Rockwell C45 hardness for reliable, long-term fastening in demanding applications
• Precise and secure installation enabled by the 1.3 mm hex drive, providing superior torque transfer and reducing the risk of tool slippage
• Optimized for quick assembly with a coarse thread pitch (0.45 mm), allowing for faster installation and reduced assembly time
• Consistent and reliable fit ensured by the Class 5g6g thread tolerance, providing predictable performance and interchangeability
• Secure flat tip design creates positive contact points on shafts and components, minimizing movement and slippage
• Full regulatory compliance with RoHS 3 and REACH, making it suitable for use in regulated industries and global markets
• Compact headless profile allows for flush mounting in tight spaces where protruding fastener heads are not feasible

Professional Applications & Engineering Value

This M2.5 set screw is engineered to solve critical challenges in precision assembly and machinery. The alloy steel material, hardened to Rockwell C45, provides the necessary strength to resist vibrational loosening and maintain clamp load in dynamic environments. The hex drive and headless design are ideal for applications where space is constrained and a clean, flush finish is required, such as in securing collars, gears, and pulleys onto shafts. The coarse pitch metric thread ensures rapid installation and robust holding in softer materials or when frequent adjustments are needed. Manufactured to DIN 913/ISO 4026 standards, it guarantees dimensional consistency and reliability for OEMs and MRO professionals in automotive, electronics, and industrial equipment sectors.

Specification Summary & Compliance

This set screw features a M2.5 x 0.45 mm coarse pitch thread with a Class 5g6g tolerance for precise fit. The 5 mm length and flat tip are specified per the DIN 913 / ISO 4026 standard. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free from hazardous substances and suitable for use in environmentally conscious manufacturing processes.
