Key Features & Benefits at a Glance
- Permanent vibration resistance with nylon patch thread locker that maintains integrity across extreme temperatures from -50° to 250° F
- Superior corrosion protection through black-oxide coating on alloy steel, extending service life in demanding industrial environments
- High-strength performance backed by Rockwell C45 hardness, ensuring reliable clamping force and resistance to wear
- Secure installation and removal with 2 mm hex drive in a headless design, ideal for confined spaces and flush mounting applications
- Precision thread engagement with Class 5g6g metric coarse thread (M4 x 0.7mm), providing consistent fit and reduced cross-threading risk
- Enhanced grip and positioning due to the cup tip design, which minimizes surface damage while improving component alignment
- Global compliance assurance meeting DIN 916/ISO 4029 standards, RoHS 3, and REACH for reliable sourcing and environmental responsibility
Professional Applications & Engineering Value
This M4 set screw delivers critical holding power in precision assemblies where vibration resistance and space constraints are paramount. The black-oxide alloy steel construction offers durability against rust and abrasion, while the nylon patch locking feature eliminates the need for additional fastening components, reducing assembly time and cost. Its headless design and hex drive enable secure installation in tight spaces commonly found in machinery, automotive, and electronics enclosures. The Class 5g6g thread fit and coarse thread pitch ensure quick, reliable engagement, making it an optimal choice for high-volume production lines and maintenance operations requiring repeatable performance.
Specification Summary & Compliance
Manufactured to Class 5g6g thread fit tolerances per metric coarse thread standards (M4 x 0.7mm x 6mm). Complies with DIN 916/ISO 4029 specifications for dimensional accuracy and performance. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental and safety standards are upheld in industrial applications.
