Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, ensuring long-term reliability in demanding industrial environments.
- Effortless self-tapping installation with Type F thread cutting design, eliminating the need for pre-tapped holes in materials like aluminum and brass.
- High-torque driving capability provided by the Phillips No. 3 drive, reducing cam-out and improving assembly efficiency.
- Optimal flush mounting with a standard 82° flat head profile, creating a smooth surface finish in sheet metal and cast iron applications.
- Maximum thread engagement and holding power through fully threaded coarse UNC design, preventing loosening under vibration.
- Wide material compatibility for use in aluminum, brass, cast iron, and sheet metal, offering versatile fastening solutions.
- Regulatory compliance assurance meeting ASME B18.6.3 and RoHS 3 standards, guaranteeing quality and environmental safety.
Professional Applications & Engineering Value
These 12-24 UNC tapping screws are precision-engineered to solve common industrial fastening challenges in aluminum, brass, cast iron, and sheet metal assemblies. The zinc-plated steel material provides essential corrosion protection, while the thread cutting (Type F) design enables direct installation without pre-tapping—significantly reducing labor time and tooling costs. The coarse UNC threads and full threading ensure superior pull-out resistance and vibration resistance in soft metals and thin materials. With an 82° countersink angle and Phillips drive, these screws deliver reliable, flush-mount performance ideal for HVAC, automotive, and machinery applications where precision and durability are critical.
Specification Summary & Compliance
This product features 12-24 UNC coarse threads with standard thread tolerances, 1" length, and fully threaded shank design. Manufactured in compliance with ASME B18.6.3 specifications (SAE J933) for dimensional accuracy and performance. Meets RoHS 3 (2015/863/EU) environmental standards, ensuring lead-free and hazardous substance compliance for global industrial use.
