Professional Applications & Engineering Value
This M8 thumb screw with knurled round head addresses critical assembly challenges where frequent adjustments or tool-free operation are required. The 18-8 stainless steel construction provides excellent corrosion resistance for industrial environments, while the coarse thread (1.25mm pitch) ensures rapid installation in machinery, electronic enclosures, and equipment panels. The fully threaded design maintains consistent clamping force across the entire 20mm length, making it ideal for applications requiring precise positioning or regular maintenance access. With 80,000 psi tensile strength, these metric thumb screws deliver reliable performance in vibration-prone applications without compromising on durability or ease of use.
Specification Summary & Compliance
Manufactured to DIN 464 specifications with Class 6g thread fit ensuring precise metric threading compatibility. The M8 x 1.25 mm coarse thread with right-hand direction provides standard engagement across industrial components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe use in regulated industries. The 30mm head diameter with 6mm height and 16mm collar diameter maintains dimensional consistency for replacement and OEM applications.
