S-93406A298 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Corrosion-resistant 18-8 stainless steel construction ensures long-term durability in harsh industrial environments
• Wide truss head design provides superior load distribution and prevents pull-through in thin sheet materials
• Thread forming technology creates strong, permanent threads without chips or debris in sheet metal applications
• Fully threaded shank delivers maximum grip length and holding power throughout the entire fastener
• No. 3 Phillips drive offers reliable torque transmission and reduces cam-out during installation
• Precision-engineered A/AB thread type ensures consistent performance and reliable fastening in sheet metal up to 0.025" thickness
• Comprehensive regulatory compliance meets RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These No. 12 x 1-1/4" Phillips truss head tapping screws are specifically engineered for demanding sheet metal applications where reliability and corrosion resistance are critical. The 18-8 stainless steel composition provides excellent resistance to oxidation and chemical exposure, making these thread forming screws ideal for outdoor equipment, HVAC systems, and electronic enclosures. The wide truss head profile distributes clamping force effectively across a larger surface area, preventing deformation of thin materials while the thread forming design creates precise, secure mating threads without generating metal chips that could compromise electrical components or moving parts. This combination of corrosion-resistant material and engineered thread form delivers long-term fastening integrity in challenging industrial environments.

Specification Summary & Compliance

These tapping screws feature precision No. 12 size with 0.216" thread diameter and 11 threads per inch in right-hand direction. The A/AB thread forming type conforms to industry standards for sheet metal fastening applications, requiring a 3/16" drill bit for proper installation. Manufactured to exacting dimensional tolerances with fully threaded design and pointed tip for easy starting. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
