- High mechanical strength and load-bearing capability with 70,000 psi tensile strength and Rockwell B84 hardness for reliable performance.
- Quick and easy installation with a coarse M4 x 0.7 mm thread and Class 6g fit, ensuring smooth engagement and secure fastening.
- Space-saving low-profile head design (3.5 mm height) ideal for applications with limited clearance.
- Full threading for maximum holding power along the entire 12 mm length, providing consistent clamping force.
- Compliance with international standards including DIN 653, RoHS 3, and REACH, ensuring safety and regulatory acceptance.
Professional Applications & Engineering Value
This M4 thumb screw is engineered to solve common industrial challenges such as tool-free assembly, frequent maintenance access, and corrosion in harsh conditions. The black-oxide steel material offers excellent resistance to oxidation, while the low-profile knurled head ensures a secure grip even with oily hands or gloves. Its metric coarse thread (0.7 mm pitch) and Class 6g thread fit provide reliable engagement in metals and plastics, reducing cross-threading risks. Ideal for electronics enclosures, machinery panels, and automotive components, this fully threaded thumb screw delivers consistent performance where quick disassembly and high tensile strength (70,000 psi) are critical.
Specification Summary & Compliance
The screw features a Class 6g thread fit per ISO metric standards, ensuring precise dimensional accuracy. It is manufactured to meet DIN 653 specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free from hazardous substances and safe for industrial use.
