S-93245A643 M5 x 30 mm DIN 913, ISO 4026 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with Rockwell C45 hardness alloy steel construction, resisting deformation under high stress
• Secure, flush installation thanks to the headless and flat tip design, ideal for confined spaces and smooth surfaces
• Reliable, coarse threading (0.8mm pitch) for faster installation and superior resistance to vibration loosening
• Precise Class 5g6g thread fit ensures consistent engagement and optimal clamping force in demanding applications
• Robust 2.5mm hex drive provides high torque transmission and reduces the risk of tool slippage and damage
• Full compliance with DIN 913 and ISO 4026 standards, guaranteeing dimensional accuracy and interchangeability
• Environmentally responsible manufacturing, meeting RoHS 3 and REACH regulations for safe use in regulated industries

Professional Applications & Engineering Value

This M5x0.8x30mm alloy steel set screw is engineered to solve critical challenges in industrial assembly and precision machinery. The headless design and flat tip allow for a completely flush finish, preventing interference in moving parts and enabling use in recessed or tight-clearance applications. Manufactured from high-strength alloy steel and heat-treated to a Rockwell C45 hardness, it provides exceptional resistance to wear and shear forces, ensuring that components like gears, pulleys, and collars remain securely locked onto shafts. The right-hand coarse thread (Metric) and hex drive facilitate quick and secure installation with standard tools, making it a reliable fastener for maintenance and production lines where vibration resistance and long-term reliability are paramount.

Specification Summary & Compliance

This metric set screw features an M5 thread size with a 0.8mm coarse pitch and a precise Class 5g6g thread fit per ISO standards, ensuring excellent dimensional accuracy. It is manufactured to conform to DIN 913 and ISO 4026 specifications, guaranteeing consistent performance and interchangeability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, affirming its suitability for use in environmentally conscious and regulated industrial applications.
