Key Features & Benefits at a Glance
- Superior holding power with Rockwell C45 hardness alloy steel for reliable, long-term fastening in demanding applications.
- Precise Class 5g6g thread fit ensures smooth installation and a secure, vibration-resistant connection.
- Compact, headless design allows for flush mounting in tight spaces where protrusion is not permissible.
- Hex drive style provides high torque transmission and reduces the risk of tool slippage during installation.
- Cup tip design bites into the contact surface for enhanced anti-loosening and rotational security.
- Coarse 0.5 mm pitch thread enables quicker assembly and is less prone to clogging with debris.
- Compliance with DIN 916/ISO 4029 standards guarantees dimensional accuracy and interchangeability.
Professional Applications & Engineering Value
This M3 set screw is engineered to solve critical challenges in precision machinery and equipment assembly. Its alloy steel construction and Rockwell C45 hardness provide exceptional resistance to wear and deformation under load, making it ideal for securing gears, pulleys, and collars on shafts. The headless and hex drive design allows for a completely flush finish, essential in rotating components to prevent interference. The cup tip creates a small indentation in the shaft, offering superior resistance to loosening from vibrations—a common failure point in dynamic industrial environments. Fully compliant with DIN 916 and ISO 4029 standards, this metric set screw ensures reliable performance and easy sourcing for maintenance and production lines.
Specification Summary & Compliance
This set screw adheres to precise dimensional standards, including a Class 5g6g thread fit per ISO metric specifications, ensuring excellent interchangeability. The manufacturing and material specifications fully conform to DIN 916 ISO 4029. Furthermore, this product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting the latest environmental and safety regulations for industrial use.
