S-90417A116 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior plastic retention with tri-lobe shank design that creates secure, vibration-resistant assemblies
• Eliminates the need for pre-tapped holes through thread forming technology, reducing installation time and costs
• Enhanced corrosion resistance with black-oxide steel construction for extended service life in industrial environments
• Optimized drive efficiency with Phillips No. 1 drive that provides reliable torque transfer and reduces cam-out
• Precision thread engagement with 0.112" diameter and 20 threads per inch for consistent performance in plastic materials
• Simplified installation process using standard No. 37 drill bit (0.104" diameter) for perfect hole preparation
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing applications

Professional Applications & Engineering Value

These TRS tapping screws are specifically engineered to address common challenges in plastic fastening applications where traditional fasteners often fail. The thread forming technology creates strong, permanent threads in plastic materials without generating chips or stress cracks that can compromise structural integrity. The tri-lobe shank cross-section provides exceptional resistance to vibration loosening, making these black-oxide steel screws ideal for automotive trim, electronic enclosures, and consumer products where reliability is critical. The combination of Phillips drive and blunt tip design ensures straightforward installation while preventing material damage, delivering consistent performance across high-volume production environments.

Specification Summary & Compliance

These No. 4 x 1/4" screws feature precision thread forming (TRS) technology with fully threaded right-hand orientation and standard inch measurements. The fasteners maintain consistent 0.112" thread diameter with 20 threads per inch and are designed for use with No. 37 drill bits (0.104" diameter). Manufacturing and material compliance includes full adherence to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring suitability for regulated industrial applications worldwide.
