S-90198A158 Length 3/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications.
• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing assembly time and labor costs.
• Optimized for sheet metal up to 0.025" thick, providing reliable fastening with maximum material engagement and vibration resistance.
• Standard 82° flat head ensures a flush, clean finish when countersunk, improving safety and aesthetic appeal in assembled products.
• Phillips No. 2 drive offers widespread tool compatibility and controlled torque application, minimizing cam-out and driver slippage.
• Fully threaded shank delivers consistent holding power along the entire 3/4" length, enhancing joint integrity in thin materials.
• Compliant with RoHS 3 and REACH regulations, ensuring environmental safety and meeting global supply chain requirements for industrial components.

Professional Applications & Engineering Value

These 316 stainless steel Phillips flat head tapping screws are precision-engineered for demanding sheet metal assembly applications, from HVAC systems and electrical enclosures to automotive panels and machinery guards. The thread forming design eliminates the need for separate tapping operations, reducing production steps and the risk of cross-threading. The 18 TPI thread pitch and 0.138" thread diameter provide excellent pull-out strength and resistance to loosening under dynamic loads. Combined with the corrosion-resistant properties of 316 stainless steel, these screws ensure long-term reliability in moist, chemical, or saline environments, preventing fastener failure and maintenance downtime.

Specification Summary & Compliance

This No. 6 x 3/4" tapping screw features a standard 82° countersink angle and fully threaded shank with right-hand thread direction. Manufactured to Type A/AB thread forming standards for sheet metal, it requires a No. 32 drill bit (0.116" diameter) for pilot holes. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to strict environmental and safety standards for industrial fasteners.
