S-90380A264 Length 3/16" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic with tri-lobe shank design that displaces material to create permanent, vibration-resistant threads
• Corrosion-resistant zinc plating provides durable surface protection for extended service life in various industrial environments
• Efficient thread forming action eliminates chip accumulation and prevents material stress cracking in plastic components
• Reliable Phillips No. 1 drive ensures secure tool engagement and consistent installation torque across production runs
• Full threading along the 3/16" length delivers maximum grip strength and uniform stress distribution
• Precision-matched drill bit sizing (No. 43/0.089") enables perfect pilot hole preparation for optimal thread formation
• Comprehensive regulatory compliance meets RoHS 3 and REACH standards for global manufacturing requirements

Professional Applications & Engineering Value

These zinc-plated steel TRS tapping screws are specifically engineered for plastic assembly applications where traditional fasteners fail. The tri-lobe shank cross-section and thread forming design solve critical industrial challenges by eliminating loose fittings and material damage common in plastic components. As the screw advances, the TRS (Thread Rolling Screw) profile cold-forms precise mating threads without creating chips or stress points that compromise structural integrity. This makes them ideal for electronics enclosures, automotive trim, and consumer products where vibration resistance and clean installation are paramount. The combination of 0.099" thread diameter and 24 TPI pitch provides optimal balance between holding strength and material displacement in various plastic densities.

Specification Summary & Compliance

Manufactured to precise inch system specifications with Class 2A thread tolerances and fully threaded configuration. Features standard pan head profile with Phillips drive compatibility. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial applications. Designed for use with No. 43 drill bit (0.089" diameter) for proper pilot hole preparation in plastic materials.
