S-93880A240 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding environments
• Efficient thread forming technology creates strong, permanent threads in sheet metal without chips or debris
• Secure installation and removal with external hex/slotted head design providing multiple drive options
• Enhanced load distribution through integrated flange design that eliminates the need for separate washers
• Precision compatibility with No. 21 drill bits (0.159" diameter) for streamlined assembly processes
• Full threading engagement along the entire 3/8" length ensures maximum holding power in thin materials
• Environmental compliance assurance meeting RoHS 3 standards for sustainable manufacturing practices

Professional Applications & Engineering Value

These No. 10 zinc-plated steel tapping screws deliver exceptional performance in sheet metal applications where vibration resistance and permanent fastening are critical. The thread forming Type B design displaces material rather than cutting it, creating stronger threads with superior resistance to loosening under dynamic loads. The combination of external hex/slotted drive provides flexibility for both power and manual tooling, while the flanged construction distributes clamping force evenly, preventing material distortion in thin-gauge metals. With 16 threads per inch and 0.19" thread diameter, these screws achieve optimal engagement in pre-drilled holes, making them ideal for HVAC systems, electronic enclosures, and automotive components requiring reliable, vibration-resistant fastening solutions.

Specification Summary & Compliance

This tapping screw features precise inch system dimensions including 0.313" hex head width, 3/8" length, and 0.414" flange diameter with Class 2A thread tolerances. Manufactured to industry standards for thread forming Type B screws with right-hand threading and blunt tip design. The product is fully RoHS 3 (2015/863/EU) compliant, ensuring environmental responsibility while maintaining the mechanical properties required for industrial sheet metal fastening applications.
