S-95115A115 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in harsh industrial environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without pre-tapping requirements
• Maximum driving torque capability through drilled spanner drive design that prevents tool slippage and head stripping
• Complete material engagement with fully threaded shank for superior holding power across the entire fastener length
• Flush installation profile with standard 82° flat head countersink for smooth, snag-free surfaces in sheet metal applications
• Precision sizing compatibility with No. 32 drill bit (0.116" diameter) for perfect fit in designated sheet metal thicknesses
• Environmental compliance assurance meeting RoHS 3 and REACH standards for safe use in regulated industries

Professional Applications & Engineering Value

These 18-8 stainless steel flat head tapping screws deliver exceptional value in sheet metal fabrication and assembly operations. The thread forming design eliminates the need for separate tapping operations, significantly reducing installation time and labor costs while creating stronger thread engagement than cutting alternatives. The drilled spanner drive provides superior torque transmission compared to standard slotted heads, preventing costly stripping during high-torque applications. With full threading along the entire 1/2" length, these screws maintain consistent clamping force across the entire material thickness, crucial for vibration-resistant assemblies in HVAC, electrical enclosures, and machinery panels. The corrosion-resistant 18-8 stainless steel composition ensures reliable performance in environments exposed to moisture, chemicals, or outdoor conditions.

Specification Summary & Compliance

These No. 6-18 x 1/2" tapping screws feature precision thread forming technology (Type A/AB) with right-hand threading and 18 TPI specification. The flat head design incorporates an 82° countersink angle for standard flush mounting applications. Manufactured to exacting dimensional standards with 0.138" thread diameter and compatible with No. 32 drill bits (0.116" diameter) for optimal performance in sheet metal up to 0.025" thickness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
