S-93245A177 M12 x 30 mm DIN 913, ISO 4026 Set Screws

Key Features & Benefits at a Glance

• Superior holding power with alloy steel construction and Rockwell C45 hardness for exceptional resistance to loosening under vibration and heavy loads
• Precise and reliable fastening ensured by Class 5g6g thread fit, providing consistent clamping force and reducing assembly errors
• Optimized for high-torque applications featuring a 6mm hex drive that allows for secure tool engagement and easy installation in confined spaces
• Enhanced durability in demanding environments due to the coarse 1.75mm pitch thread, which resists clogging and is less prone to cross-threading
• Flush and secure mounting achieved with the headless design and flat tip, ideal for permanent positioning of components on shafts and hubs
• Guaranteed material integrity and performance consistency through compliance with DIN 913 and ISO 4026 manufacturing standards
• Safe for regulated industries with full RoHS 3 and REACH compliance, ensuring no hazardous substances and meeting global environmental directives

Professional Applications & Engineering Value

This M12 metric set screw is engineered to address critical challenges in industrial assembly and machinery maintenance. The alloy steel composition, hardened to Rockwell C45, provides the necessary strength to prevent stripping and deformation under high stress, making it ideal for securing gears, pulleys, and collars on rotating shafts. The hex headless design and flat tip allow for flush installation, eliminating protrusions that could interfere with moving parts. With its coarse thread pitch of 1.75mm, this screw offers faster installation and superior resistance to vibration loosening compared to fine-thread alternatives. It is widely used in automotive, manufacturing, and heavy equipment applications where reliable, permanent fastening is essential. Compliance with DIN 913/ISO 4026 ensures dimensional accuracy and interchangeability, reducing downtime and maintenance costs.
