Key Features & Benefits at a Glance
- Vibration-resistant locking with nylon patch thread locker that maintains secure fastening in temperatures from -50° to 250°F
- Superior corrosion protection through black-oxide coating on alloy steel, extending service life in demanding environments
- High-strength performance with Rockwell C45 hardness for reliable load-bearing capacity and durability
- Precision thread engagement with Class 5g6g thread fit ensuring consistent mating and reduced assembly issues
- Space-saving headless design allowing flush mounting where clearance is limited
- Easy installation and removal using standard 2 mm hex drive tools for efficient maintenance
- Secure cup tip design providing excellent grip and resistance to loosening under dynamic loads
Professional Applications & Engineering Value
This M4 set screw with nylon patch locking addresses critical vibration-induced loosening in industrial machinery, automotive components, and precision equipment. The black-oxide alloy steel construction combined with Rockwell C45 hardness ensures reliable performance under high-stress conditions, while the coarse metric thread (0.7 mm pitch) facilitates quick assembly and disassembly. The headless hex drive design is ideal for confined spaces where protruding fasteners are impractical, making it particularly valuable for industrial set screws applications requiring both security and accessibility. Meeting DIN 916/ISO 4029 standards guarantees dimensional consistency and interchangeability across global manufacturing operations.
Specification Summary & Compliance
This metric set screw features M4 x 0.7 mm coarse threads with Class 5g6g thread fit tolerance for precise engagement. Manufactured to DIN 916/ISO 4029 specifications, it ensures dimensional accuracy and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, supporting sustainable procurement practices in industrial supply chains.
