S-93406A307 Length 2 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding industrial environments
• Enhanced load distribution from the wide truss head design, reducing material stress and preventing pull-through in sheet metal applications
• Efficient thread forming capability creates strong, permanent threads without pre-tapping, saving installation time and labor costs
• Secure fastening with Phillips No. 3 drive provides reliable torque transmission and reduces cam-out during installation
• Full threading along the 2-1/2" length ensures maximum grip strength and uniform stress distribution across the entire fastener
• Comprehensive regulatory compliance with RoHS 3 and REACH standards for safe, environmentally responsible manufacturing
• Optimized for 3/16" drill bits with precise thread diameter matching for clean installations in sheet metal up to 0.025" thickness

Professional Applications & Engineering Value

These 18-8 stainless steel truss head tapping screws deliver exceptional value in sheet metal fabrication and industrial assembly applications. The thread forming design eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that won't loosen under stress. The wide truss head profile distributes clamping force over a larger surface area, preventing deformation in thin gauge materials while providing superior pull-out resistance. Manufactured from corrosion-resistant 18-8 stainless steel, these Phillips drive screws maintain integrity in harsh environments, making them ideal for HVAC systems, electrical enclosures, and metal framework assembly where durability and reliability are critical.

Specification Summary & Compliance

These No. 12 x 2-1/2" tapping screws feature precise 0.216" thread diameter with 11 threads per inch and fully threaded right-hand configuration. The A/AB screw type follows industry-standard thread forming specifications for consistent performance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. Designed for use with 3/16" drill bits, these screws provide reliable fastening in materials up to 0.025" maximum drilling thickness.
