S-90086A245 10-24 x 3/4" ASME B18.6.3, SAE J933 Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Self-tapping efficiency with Type F thread cutting design eliminates need for pre-tapped holes, reducing installation time and labor costs
• Optimized material compatibility specifically engineered for aluminum, brass, cast iron, and sheet metal applications
• Enhanced driving performance with Phillips No. 2 drive providing secure tool engagement and reduced cam-out risk
• Precision flush mounting with standard flat head profile and 82° countersink angle for clean, professional finishes
• Reliable coarse thread engagement with UNC 10-24 threading ensuring strong holding power in various materials
• Full-length threading maximizes grip strength and distributes load evenly across the entire fastener length

Professional Applications & Engineering Value

These 10-24 UNC zinc-plated steel tapping screws deliver exceptional engineering value by solving critical fastening challenges in metal fabrication and assembly operations. The thread cutting design (Type F) creates precise mating threads in ductile materials without pre-tapping, significantly reducing installation time and eliminating secondary operations. The coarse thread spacing provides superior pull-out resistance in softer metals like aluminum and brass, while the zinc plating offers essential corrosion protection for industrial environments. Engineered with a standard flat head profile and 82° countersink angle, these screws sit flush with surfaces, preventing snagging and ensuring smooth finishes in sheet metal applications, electrical enclosures, and machinery assemblies where protrusions could compromise safety or function.
