S-93406A204 Length 1 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh environments
• Enhanced load distribution from the wide truss head design, reducing material stress and preventing pull-through
• Strong, reliable fastening through thread forming technology, creating secure threads without pre-tapping in sheet metal
• Full-thread engagement along the 1-3/4" length for maximum holding power and vibration resistance
• Easy installation with Phillips No. 2 drive and compatibility with standard No. 29 drill bits
• Optimized for thin materials, effectively fastening sheet metal up to 0.025" thickness
• Regulatory compliance with RoHS 3 and REACH standards for safe industrial use

Professional Applications & Engineering Value

These No. 8 Phillips truss head tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and material integrity are critical. The 18-8 stainless steel composition provides excellent corrosion resistance, making these thread forming screws ideal for outdoor equipment, HVAC systems, and electronic enclosures exposed to moisture. The wide truss head design significantly increases bearing surface area, distributing clamp load over a broader area to prevent distortion in thin-gauge materials. With their A/AB thread forming technology, these screws create precise mating threads in pre-drilled holes without generating chips, eliminating contamination concerns in sensitive assemblies. The combination of fully threaded shank and 15 threads per inch pitch ensures maximum thread engagement for superior pull-out strength in demanding industrial environments.

Specification Summary & Compliance

This No. 8 x 1-3/4" tapping screw features a 0.164" thread diameter with 15 threads per inch right-hand threading and complies with standard A/AB thread forming specifications. The screw is designed for use with No. 29 drill bits (0.136" diameter) and accommodates sheet metal thicknesses up to 0.025". Manufacturing and material compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and industrial standards adherence.
