S-90380A251 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior thread forming in plastics with TRS-type tri-lobe shank design for reliable, vibration-resistant fastening without pre-tapping
• Enhanced corrosion resistance through zinc-plated steel construction, extending service life in various industrial environments
• Optimized drive efficiency with Phillips No. 2 drive that provides secure tool engagement and reduces cam-out during installation
• Maximum material engagement through fully threaded design and 14 threads per inch, ensuring strong holding power in plastic assemblies
• Simplified installation process with compatible No. 15 drill bit (0.18" diameter) requirements, reducing assembly time and errors
• Versatile pan head design with 0.373" diameter provides excellent bearing surface while maintaining low profile for space-constrained applications
• Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing and supply chain requirements

Professional Applications & Engineering Value

These No. 10 zinc-plated steel tapping screws deliver exceptional engineering value in plastic assembly applications where traditional fastening methods often fail. The TRS-type thread forming design with tri-lobe shank cross-section displaces plastic material during installation, creating strong, permanent threads without chips or debris. This thread forming technology eliminates the need for threaded inserts in many applications, reducing component costs and assembly complexity. The zinc-plated steel construction provides necessary corrosion protection while maintaining the strength required for high-stress plastic joints. With fully threaded configuration and 14 threads per inch density, these screws distribute clamping force evenly, preventing stress concentration and material cracking in brittle plastics commonly used in electronics enclosures, automotive components, and industrial equipment.

Specification Summary & Compliance

These tapping screws feature precision No. 10 thread diameter (0.19") with 14 threads per inch and 1" length in fully threaded configuration. The TRS-type thread forming design with tri-lobe shank ensures optimal performance in plastic materials when used with recommended No. 15 drill bits (0.18" diameter). Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications requiring restricted substance compliance.
