S-94629A250 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 stainless steel construction for long-lasting performance in demanding environments
• Efficient thread cutting action creates precise mating threads in plastic materials without pre-tapping
• Optimized 18 TPI thread pitch provides maximum holding power and vibration resistance in plastic assemblies
• Phillips No. 2 drive design ensures secure tool engagement and reduces cam-out during installation
• Pan head profile with 0.322" diameter offers excellent bearing surface for reliable clamping force distribution
• Full threading along 1-1/4" length allows for adjustable engagement depth and consistent fastening strength
• Environmental compliance assurance with RoHS 3 and REACH regulations for global manufacturing applications

Professional Applications & Engineering Value

These 410 stainless steel tapping screws are specifically engineered for plastic assembly applications where traditional fastening methods fail. The thread cutting design with 18 TPI threading eliminates the need for separate tapping operations, significantly reducing installation time and labor costs in high-volume production. The Phillips drive system provides reliable torque transmission while the pan head configuration ensures uniform pressure distribution across plastic surfaces, preventing material deformation or cracking. Manufactured from corrosion-resistant 410 stainless steel, these screws maintain structural integrity in humid or chemically challenging environments, making them ideal for industrial plastic components, electronic enclosures, and outdoor equipment assemblies where durability and reliability are critical.

Specification Summary & Compliance

This No. 8 x 1-1/4" tapping screw features standard inch measurements with fully threaded right-hand configuration and blunt tip design optimized for plastic materials. The screw complies with Type 25/BT thread cutting standards and is designed for use with No. 26 drill bit (0.147" diameter) for proper hole preparation. Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and unrestricted use in global industrial markets.
