S-93945A053 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ensuring long-term reliability in harsh industrial environments.
• Excellent holding power through thread forming technology, creating strong, vibration-resistant threads in sheet metal without pre-tapping.
• Secure installation and removal with square drive design, providing better torque transmission and reduced cam-out compared to Phillips drives.
• Flush surface finish with standard flat head profile and 82° countersink angle, ideal for applications requiring smooth, unobtrusive fastening.
• Full-length threading maximizes grip length and pull-out resistance across the entire 1-1/4" screw length.
• Optimized for sheet metal applications with pointed tip and specific thread design, ensuring easy penetration and reliable performance in metal up to 0.025" thickness.
• Environmental compliance assurance with RoHS 3 and REACH compliance, meeting international regulatory standards for industrial use.

Professional Applications & Engineering Value

These No. 12 tapping screws deliver exceptional engineering value in sheet metal fabrication and assembly operations. The 18-8 stainless steel composition provides outstanding corrosion resistance, making them ideal for outdoor equipment, electrical enclosures, and HVAC systems where moisture exposure is common. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating stronger, more reliable threads than cutting alternatives. The flat head with square drive combination ensures secure, flush mounting that won't protrude, while the fully threaded A/AB tapping screw configuration maintains consistent holding power throughout the fastened material. These features collectively address critical industrial pain points including vibration loosening, corrosion failure, and installation efficiency in metalworking applications.

Specification Summary & Compliance

These tapping screws feature precision 0.216" thread diameter with 11 threads per inch and Class 2A thread fit for reliable engagement. The flat head design incorporates an 82° countersink angle matching standard sheet metal applications. Manufacturing complies with A/AB tapping screw standards for thread forming applications. Environmental compliance is verified with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, ensuring adherence to international hazardous substance restrictions for industrial components.
