S-92470A050 Length 1/4" 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
• Excellent thread-forming capability with Type A/AB design creates secure, permanent threads in sheet metal without pre-tapping
• Optimized torque transfer through No. 0 Phillips drive style prevents cam-out and ensures reliable installation
• Maximum material engagement with fully threaded design and pointed tip for quick starting and superior holding power
• Standard pan head profile provides a balanced combination of low profile and adequate bearing surface
• Precision dimensional accuracy with Class 2A thread tolerances ensuring consistent performance and interchangeability
• Environmental compliance with RoHS 3 regulations for use in regulated industries and global markets

Professional Applications & Engineering Value

These Type A thread forming screws are engineered specifically for sheet metal applications where reliable fastening is critical. The 18-8 stainless steel composition provides exceptional corrosion resistance, making these tapping screws ideal for outdoor equipment, HVAC systems, and electronic enclosures exposed to moisture or chemicals. The thread forming design eliminates the need for separate tapping operations, reducing assembly time and costs while creating strong, strip-resistant threads in materials up to 0.025" thickness. The Phillips pan head configuration offers excellent drive stability during installation, while the fully threaded pointed tip ensures quick starting and smooth penetration into pre-drilled holes. These features combine to deliver consistent performance in high-volume manufacturing environments where reliability and efficiency are paramount.

Specification Summary & Compliance

This No. 1-48 x 1/4" tapping screw features inch system measurements with Class 2A thread tolerances and complies with standard Type A thread forming specifications. The screw maintains precise dimensional accuracy with 0.073" thread diameter, 48 threads per inch, and standard pan head profile (0.142" diameter, 0.053" height). Manufactured from 18-8 stainless steel with RoHS 3 (2015/863/EU) compliance, this fastener meets environmental regulations for industrial applications. The combination of right-hand threading, round shank cross-section, and No. 0 Phillips drive ensures compatibility with standard installation tools and procedures.
