S-90627A116 Length 3/8" ASME B18.6.3 Tapping Screws

Key Features & Benefits at a Glance

• Superior vibration resistance through DST thread forming technology that creates permanent, secure threads in plastic materials
• Enhanced corrosion protection with black zinc-plated steel construction for extended service life in demanding environments
• Maximum holding power achieved through fully threaded design that distributes load evenly across the entire fastener length
• Reliable installation performance with Phillips No. 2 drive that prevents cam-out and ensures consistent torque application
• Optimized for plastic applications featuring blunt tip design that prevents material splitting while maintaining precise thread engagement
• Industry-standard compliance meeting ASME B18.6.3 specifications for consistent quality and dimensional accuracy
• Perfect thread match with 19 TPI configuration specifically engineered for secure fastening in plastic substrates

Professional Applications & Engineering Value

These DST thread forming screws are specifically engineered to address common challenges in plastic fastening applications, where traditional threaded fasteners often fail. The thread forming technology displaces material rather than removing it, creating stronger, more vibration-resistant connections that won't loosen under stress. The black zinc-plated steel construction provides essential corrosion resistance for industrial environments, while the fully threaded design ensures maximum pull-out strength across the entire engagement length. The Phillips drive system offers reliable installation with standard tools, making these tapping screws ideal for assembly lines in automotive trim, electronic enclosures, and consumer products where plastic components require durable, long-lasting fastening solutions.

Specification Summary & Compliance

Manufactured to exact ASME B18.6.3 standards, these screws maintain precise dimensional tolerances with 0.138" thread diameter and 19 TPI configuration. The 3/8" length and No. 6 screw size provide consistent performance when used with recommended No. 35 drill bit (0.11" diameter). The right-hand thread direction and standard pan head design ensure compatibility with industry-standard installation practices. All components comply with relevant industrial specifications for thread forming screws in plastic applications.
