S-93406A148 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments
• Enhanced load distribution from the wide truss head design, reducing material stress and preventing pull-through
• Efficient thread forming capability creates strong, permanent threads in sheet metal without pre-tapping
• Optimized driving performance with Phillips No. 2 drive for secure torque transfer and reduced cam-out
• Maximum material engagement through fully threaded design, ensuring superior holding power in thin materials
• Precision installation with No. 32 drill bit compatibility for clean, accurate hole preparation
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These 18-8 stainless steel tapping screws deliver exceptional engineering value in sheet metal applications where corrosion resistance and structural integrity are paramount. The thread forming design eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that withstand industrial stresses. The wide truss head profile provides superior clamping force distribution across a larger surface area, preventing material deformation in thin-gauge metals up to 0.025" thickness. With fully threaded construction and Phillips drive compatibility, these A/AB tapping screws ensure maximum thread engagement and reliable installation in HVAC systems, electronic enclosures, and automotive assemblies where durability and compliance are critical.

Specification Summary & Compliance

This No. 6 x 1/2" tapping screw features precision 0.138" thread diameter with 18 threads per inch in right-hand orientation, manufactured to standard thread forming specifications for consistent performance. The screw maintains dimensional accuracy with 0.321" head diameter and No. 2 Phillips drive size for uniform installation. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial use worldwide.
