S-92905A219 M6 x 18 mm DIN 915, ISO 4028 Set Screws

Key Features & Benefits at a Glance

• Exceptional holding power with Rockwell C45 hardness alloy steel construction, resisting deformation under high torque and vibration.
• Secure and flush installation thanks to the headless and hex drive design, ideal for applications where protruding components are not permitted.
• Reliable and fast assembly with a Class 6g thread fit and coarse M6x1 mm thread, ensuring consistent engagement and reducing cross-threading risks.
• Enhanced grip and positioning from the extended 3.25 mm tip, providing superior bite into the mating material for a more permanent fixture.
• Broad industrial compatibility by conforming to DIN 915 and ISO 4028 standards, guaranteeing dimensional precision and interchangeability.
• Long-term operational safety with compliance to RoHS 3 and REACH regulations, ensuring the fastener is free from hazardous substances.
• Optimized for high-stress applications where a robust, headless set screw is required to secure collars, gears, and pulleys on shafts.

Professional Applications & Engineering Value

This M6 set screw is engineered to solve critical fastening challenges in demanding industrial applications. The use of alloy steel and a Rockwell C45 hardness rating provides the necessary high-strength to prevent loosening under persistent vibration and dynamic loads, a common failure point in machinery. The headless design with a hex drive allows for a completely flush mount, which is essential in compact assemblies and rotating components where clearance is limited. The extended tip with precise tolerances bites decisively into shafts, creating a secure point that resists slippage, making it an ideal metric fastener for permanently locating components on right-hand thread systems. Its compliance with major international standards ensures reliability and ease of sourcing for global engineering projects.

Specification Summary & Compliance

This set screw features an M6 x 1 mm coarse thread with a Class 6g tolerance for a secure fit. The extended tip has a diameter of 4 mm (-0.3mm to 0) and a length of 3.25 mm (-0.25mm to 0). Manufacturing and quality are governed by the DIN 915 and ISO 4028 specifications. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations.
