S-99607A314 M8 x 16 mm Thumb Screws

Key Features & Benefits at a Glance

• Effortless hand-tightening and removal with a 16.5 mm diameter knurled round head for superior grip, even with gloves or oily hands.
• Exceptional corrosion resistance provided by 18-8 Stainless Steel, ensuring long-term reliability in harsh or humid environments.
• High mechanical strength and durability with a Rockwell B85 hardness and 80,000 psi tensile strength to withstand significant operational stress.
• Secure and stable seating due to the integrated flared collar design, which helps prevent over-tightening and distributes load effectively.
• Reliable and precise engagement with a coarse M8 x 1.25 mm thread and Class 6g fit, enabling quick assembly and a secure hold.
• Versatile and ready for use as a fully threaded screw, providing consistent clamping force along the entire 16 mm length.
• Safe for regulated industries, being fully compliant with RoHS 3 and REACH environmental regulations.

Professional Applications & Engineering Value

This M8 thumb screw is engineered to solve common industrial fastening challenges where tool-less operation and frequent adjustments are required. The 18-8 stainless steel construction offers excellent resistance to rust and corrosion, making it ideal for use in electrical enclosures, machinery panels, and outdoor equipment. The knurled head and flared collar work in tandem to provide a non-slip grip and prevent the screw from digging into softer materials, protecting surfaces and ensuring repeated use without failure. With its coarse thread and Class 6g fit, it allows for rapid installation and a secure fit in a wide range of pre-tapped holes, reducing assembly time and maintenance costs in production and maintenance settings.

Specification Summary & Compliance
