S-92552A482 M8 x 30 mm DIN 653 Thumb Screws

Key Features & Benefits at a Glance

• Enhanced grip and torque application with a 30mm diameter knurled round head for secure hand-tightening without tools
• Superior corrosion resistance and durability thanks to the black-oxide steel finish, extending service life in various environments
• High mechanical strength and load-bearing capability with a Rockwell B84 hardness and 70,000 psi tensile strength for demanding applications
• Reliable and precise fastening ensured by the M8 coarse thread with Class 6g fit and 1.25mm pitch for quick installation and vibration resistance
• Full-thread engagement for maximum holding power across the entire 30mm length, providing consistent clamping force
• Low-profile design for space-constrained assemblies with a 6mm head height, ideal for compact equipment and panels
• Compliance with international standards including DIN 653, RoHS 3, and REACH for quality assurance and environmental safety

Professional Applications & Engineering Value

This M8 thumb screw is engineered to address common industrial challenges such as frequent adjustments and tool-less access in maintenance-heavy environments. The black-oxide steel construction offers excellent resistance to rust and wear, making it suitable for automotive, electronics, and machinery applications where durability is critical. The knurled thumb screw head provides a non-slip surface, allowing operators to apply sufficient torque by hand, reducing downtime and tool dependency. With a coarse thread and Class 6g thread fit, it ensures quick assembly and reliable performance in high-vibration settings, while the low-profile round head minimizes protrusion in compact designs. Ideal for securing panels, access doors, and fixtures, this screw combines user convenience with robust engineering for efficient B2B operations.

Specification Summary & Compliance
