Professional Applications & Engineering Value
This M4 thumb screw delivers critical engineering advantages through its 18-8 stainless steel composition and fully threaded design. The knurled head with flared collar prevents tool slippage while distributing clamping pressure evenly, solving common issues of damaged components and insufficient torque in maintenance panels, electronic enclosures, and machinery access points. The coarse 0.7 mm pitch and Class 6g thread fit enable rapid installation with reduced cross-threading risks, making it ideal for production lines requiring frequent adjustments. With 80,000 psi tensile strength, this metric thumb screw maintains reliability in vibration-prone applications where plastic fasteners would fail.
Specification Summary & Compliance
Manufactured to precise metric standards with M4 x 0.7 mm coarse threads meeting Class 6g tolerance for consistent fit. The fully threaded 8 mm length provides complete engagement capability. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety in industrial applications. Material certification confirms 18-8 stainless steel composition with Rockwell B85 hardness specifications.
