S-90930A249 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black protective coating extends service life in demanding environments
• Excellent thread-forming capability creates permanent, vibration-resistant threads in sheet metal without pre-tapping
• Enhanced driving efficiency with No. 2 Phillips drive prevents cam-out and reduces assembly time
• Maximum material engagement through fully threaded design ensures superior holding power
• Flanged pan head design provides wider bearing surface for secure fastening and reduced surface damage
• Precision pointed tip facilitates easy starting and accurate placement in sheet metal applications
• Environmental compliance meets RoHS 3 and REACH standards for sustainable manufacturing practices

Professional Applications & Engineering Value

These black corrosion-resistant-coated steel tapping screws deliver exceptional performance in sheet metal assembly applications where durability and reliability are paramount. The A/AB thread forming technology creates strong, permanent threads by displacing material rather than cutting it, resulting in zero chip production and superior resistance to vibration loosening. The fully threaded design maximizes grip length while the flanged pan head distributes clamping force evenly, preventing material distortion in thin-gauge metals. Engineered for use with No. 21 drill bits in materials up to 0.025" thickness, these Phillips drive screws provide reliable fastening solutions for HVAC systems, electrical enclosures, automotive panels, and industrial equipment where consistent performance under stress is critical.

Specification Summary & Compliance

This No. 10-12 x 1-1/4" tapping screw features precise 0.19" thread diameter with 12 threads per inch in right-hand orientation. The screw meets standard thread forming specifications with Class 2A thread tolerances for consistent performance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications. The combination of thread forming technology and corrosion-resistant steel construction provides reliable fastening performance in sheet metal up to 0.025" thickness when used with recommended No. 21 drill bits.
