S-93882A583 5/16"-18 x 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Enhanced installation efficiency through external hex drive design providing maximum torque transfer and reduced tool slippage
• Eliminates need for separate washers with integrated flange design that distributes clamping force and prevents material pull-through
• Exceptional thread-forming capability creates permanent, vibration-resistant threads in steel, aluminum, brass, cast iron and sheet metal without pre-tapping
• Reliable coarse UNC threading ensures quick installation and superior resistance to loosening under dynamic loads
• Full-length threading provides maximum engagement depth and holding power across the entire fastener length
• Regulatory compliance assurance meets RoHS 3 and REACH standards for global industrial applications

Professional Applications & Engineering Value

These zinc-plated steel flanged hex tapping screws deliver exceptional engineering value in metal fabrication and assembly operations. The thread forming SW type design creates precise, durable threads without generating chips, making them ideal for steel, aluminum, brass, cast iron, and sheet metal applications where debris contamination must be avoided. The external hex drive system combined with the integrated flange provides superior clamping force distribution, preventing material distortion while eliminating the need for additional washers. This 5/16"-18 UNC coarse thread configuration ensures rapid installation and maintains integrity in high-vibration environments, while the zinc plating offers reliable corrosion protection for extended service life in demanding industrial conditions.
