S-93406A044 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Enhanced load distribution from the wide truss head design that reduces material stress and prevents pull-through
• Excellent holding power through thread forming technology that creates strong, permanent threads in sheet metal
• Optimized installation efficiency with No. 0 Phillips drive for secure tool engagement and reduced cam-out
• Maximum thread engagement thanks to fully threaded design and pointed tip for easy starting and consistent fastening
• Precise fit and reduced preparation time with recommended No. 52 drill bit (0.0635") for proper hole sizing
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

This No. 1-48 thread forming screw delivers exceptional engineering value in sheet metal applications where vibration resistance and permanent fastening are critical. The 18-8 stainless steel construction provides excellent corrosion resistance, making it ideal for outdoor equipment, HVAC systems, and electronic enclosures exposed to harsh conditions. The thread forming (Type A/AB) design eliminates the need for tapping operations by displacing material to create strong, zero-clearance threads that won't loosen under vibration. The wide truss head distributes clamping force over a larger area, preventing damage to thin sheet materials while providing a secure, low-profile finish. With 48 threads per inch and fully threaded construction, this Phillips drive tapping screw ensures maximum engagement depth and superior pull-out resistance in materials up to 0.025" thickness.
