• Headless, slotted drive design allows for a flush finish in confined spaces and simple adjustment using standard slotted screwdrivers.
• Flat tip geometry offers secure contact against mating surfaces, minimizing component damage and ensuring stable positioning.
• Full compliance with DIN 551 and ISO 4766 standards guarantees consistent quality, dimensional accuracy, and interchangeability in metric assemblies.
• RoHS 3 and REACH compliant for safe use in regulated industries, ensuring environmental responsibility and material safety.

Professional Applications & Engineering Value

This M4 set screw is engineered to address critical challenges in industrial machinery, automation systems, and precision equipment where space is limited and reliable fastening is non-negotiable. The alloy steel material, combined with Rockwell B67 hardness, ensures the screw withstands high dynamic loads and repetitive stress without failing. Its headless design and slotted drive make it ideal for applications requiring a flush mounting surface, such as in shaft collars, gears, and pulleys, where protruding fastener heads could interfere with moving parts. The coarse metric thread with Class 6g fit provides excellent resistance to loosening under vibration, a common issue in motor mounts and rotating assemblies. By meeting DIN 551 and ISO 4766 specifications, this set screw delivers consistent performance, reducing the risk of assembly errors and maintenance downtime in industrial set screw applications.

Specification Summary & Compliance

This set screw features an M4 x 0.7mm coarse thread with a Class 6g tolerance for precise fit, a 20mm length, and a flat tip. It is manufactured in accordance with DIN 551 and ISO 4766 standards, ensuring dimensional accuracy and mechanical properties. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for use in environmentally conscious and regulated industries.
