S-95901A225 Length 3/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 410 Stainless Steel construction, ideal for harsh industrial environments
• Efficient thread forming with Type B design creates strong, permanent threads in sheet metal without pre-tapping
• Reliable driving performance thanks to Phillips No. 2 drive that reduces cam-out and improves torque transfer
• Optimized sheet metal engagement with 18 threads per inch providing maximum holding power in thin materials
• Secure pan head design offers excellent bearing surface and prevents over-tightening in sheet metal applications
• Full threading ensures consistent fastening strength along the entire 3/8" length
• Environmental compliance meets RoHS 3 and REACH standards for sustainable manufacturing practices

Professional Applications & Engineering Value

These No. 8 x 3/8" tapping screws are specifically engineered for sheet metal applications where reliable fastening is critical. The 410 Stainless Steel construction provides exceptional corrosion resistance, making them suitable for outdoor equipment, HVAC systems, and industrial machinery exposed to moisture and chemicals. The thread forming Type B design eliminates the need for pre-tapped holes, reducing installation time and labor costs while creating strong, permanent threads that resist vibration loosening. The Phillips pan head with No. 2 drive ensures secure installation without damaging the fastener or workpiece, while the fully threaded right-hand thread configuration delivers uniform clamping force across the entire engagement length. These screws are precision-matched with No. 29 drill bits (0.136" diameter) for optimal hole preparation and thread formation in various sheet metal thicknesses.

Specification Summary & Compliance

This thread forming Type B tapping screw features a No. 8 size with 3/8" length and 18 threads per inch configuration. The fastener maintains standard inch system tolerances with a 0.164" thread diameter and blunt tip design for controlled thread formation. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring restricted substance compliance for industrial applications worldwide. The pan head profile provides a standard bearing surface with 0.322" diameter and 0.115" height dimensions optimized for sheet metal fastening requirements.
