• Enhanced torque transmission via the 41mm external hex head, allowing for high tightening forces without stripping
• Controlled thread distribution with partial threading over 39mm of the 200mm length, ideal for applications requiring specific grip lengths
• Consistent performance assurance through compliance with DIN 6914/ISO 7412 standards, guaranteeing dimensional accuracy and interchangeability
• Safe and sustainable usage with RoHS 3 and REACH compliance, meeting stringent environmental and health regulations

Professional Applications & Engineering Value

Engineered for heavy-duty construction and industrial machinery, this M24 hex head screw addresses critical challenges in structural applications. The hot-dipped galvanized steel material provides a robust barrier against moisture and chemicals, significantly reducing maintenance costs and downtime in corrosive settings. Its Class 10.9 strength grade and Rockwell C32 hardness ensure it withstands high vibrational loads and tensile stresses, making it a reliable choice for bolting connections in steel frameworks, conveyor systems, and equipment bases. The partially threaded design with a 161mm grip length allows precise clamping force distribution, minimizing the risk of joint loosening. By adhering to DIN 6914/ISO 7412 specifications and featuring a coarse thread pitch, it simplifies installation and enhances compatibility with standard metric components, delivering consistent performance in demanding B2B environments.

Specification Summary & Compliance

This fastener maintains precise dimensional tolerances, including a Class 6g thread fit per metric standards and a 200mm overall length with 39mm threaded portion.
