Key Features & Benefits at a Glance
- Maximum holding power with Class 5g6g thread fit ensuring secure, vibration-resistant fastening in demanding applications
- Superior durability from Rockwell C45 hardness alloy steel construction, resisting wear and deformation under heavy loads
- Space-saving headless design allows flush mounting where protruding fastener heads are impractical
- Quick installation and removal with standardized 2.5mm hex drive compatible with common industrial tools
- Reliable coarse thread engagement with 0.8mm pitch providing faster assembly and reduced cross-threading risk
- Secure point contact through cup tip design that bites into mating surfaces for positive positioning
- Global compliance assurance meeting DIN 916 specifications plus RoHS 3 and REACH environmental standards
Professional Applications & Engineering Value
These M5 set screws deliver critical engineering solutions where space constraints and vibration resistance are paramount. The alloy steel construction with Rockwell C45 hardness maintains clamping force in high-stress applications like machinery collars, gear hubs, and precision tooling. The headless design enables flush mounting in confined spaces while the 2.5mm hex drive provides sufficient torque transmission without stripping. The coarse metric thread with 0.8mm pitch ensures rapid assembly in production environments and reliable performance in vibrating equipment. Cup tip configuration creates positive mechanical locking by embedding into shaft surfaces, preventing component slippage in power transmission systems and rotating assemblies.
Specification Summary & Compliance
Manufactured to DIN 916 standards with Class 5g6g thread fit tolerance ensuring precise dimensional accuracy. The metric coarse thread (M5x0.8mm) provides optimal engagement characteristics while the 18mm length offers versatile application coverage. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe use across global industrial markets.
