S-94061A225 Length 3" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in demanding industrial environments
• Efficient self-drilling capability with specialized No. 2 drill tip that eliminates pre-drilling requirements in steel and sheet metal up to 0.1" thickness
• Enhanced driving stability through Phillips No. 2 drive system that prevents cam-out and ensures secure installation
• Optimal material displacement with thread forming (BSD) design that creates stronger, vibration-resistant threads without chip generation
• Professional finished appearance with standard oval head profile and 82° countersink angle for flush mounting in various applications
• Full-thread engagement along the entire 3" length provides maximum holding power and load distribution
• Regulatory compliance assurance meeting RoHS 3 and REACH standards for safe use in industrial settings

Professional Applications & Engineering Value

These No. 8 x 3" zinc-plated steel tapping screws deliver exceptional performance in steel and sheet metal fabrication where reliability is critical. The thread forming BSD design eliminates the need for tapped holes while creating permanent, high-strength connections that resist vibration loosening. The integrated drilling tip with 7/32" length penetrates materials up to 0.1" thick without pilot holes, significantly reducing installation time and labor costs. The fully threaded configuration ensures maximum thread engagement across the entire fastener length, providing superior pull-out resistance in thin-section materials. These oval head Phillips screws combine the aesthetic benefits of a finished appearance with the mechanical advantages of a countersunk fastener, making them ideal for HVAC systems, electrical enclosures, and metal building components where both performance and appearance matter.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.164" thread diameter and 18 threads per inch configuration. Features Class 2A thread tolerances for reliable engagement and standard oval head profile with 0.312" diameter. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial safety. The thread forming tapping method follows BSD standards, creating strong, permanent threads in ductile materials without generating chips or debris.
