S-95844A350 Length 25 mm DIN 7982 Type C Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh environments and long-term reliability.
• Efficient thread forming creates strong, permanent threads in sheet metal without pre-drilling, reducing assembly time.
• Flush, secure installation with an 80° countersink angle and flat head design for a smooth finish and maximum holding power.
• Reliable drive engagement using a No. 2 Phillips drive, minimizing cam-out and ensuring consistent torque application.
• Full-length threading (M3.5 x 25mm) provides excellent grip along the entire shank for enhanced load distribution.
• Compliance with DIN 7982 Type C ensures dimensional accuracy and interchangeability for professional applications.
• RoHS 3 compliance guarantees environmentally safe materials, meeting strict international regulations.

Professional Applications & Engineering Value

These M3.5 tapping screws are precision-engineered from 18-8 stainless steel to address common challenges in sheet metal fastening. The thread forming design displaces material to create robust internal threads, eliminating the need for tapped holes and reducing the risk of strip-out in thin-gauge metals. The fully threaded shank and pointed tip facilitate easy starts and uniform stress distribution, while the Phillips flat head with an 80° countersink angle sits flush to prevent snagging and improve aesthetics. Ideal for HVAC, electronics enclosures, and automotive assemblies, these screws deliver corrosion-resistant, vibration-proof connections that withstand demanding industrial conditions.
