Key Features & Benefits at a Glance
- Superior thread cutting performance ensures reliable, secure fastening in aluminum, brass, cast iron, and sheet metal without pre-tapped holes.
- Enhanced corrosion resistance from the Black-Oxide Steel finish extends service life in demanding industrial environments.
- Coarse UNC threading provides faster installation and reduced risk of cross-threading in softer materials.
- Fully threaded design maximizes grip length and load distribution for stronger, more durable connections.
- Phillips flat head with standard 82° countersink allows for flush mounting and clean aesthetics in assembled products.
- Compliance with ASME B18.6.3 and SAE J933 standards guarantees consistent quality, dimensional accuracy, and interchangeability.
- RoHS 3 compliance ensures environmental safety and meets global regulatory requirements for hazardous substances.
Professional Applications & Engineering Value
This 6-32 UNC thread cutting tapping screw is engineered to solve common fastening challenges in metalworking and assembly. Its thread cutting design eliminates the need for separate tapping operations, reducing labor time and tooling costs when working with aluminum, brass, cast iron, and sheet metal. The Black-Oxide Steel material offers a durable, corrosion-resistant surface that withstands exposure to moisture and industrial atmospheres, prolonging component life. With a Phillips flat head and standard 82° countersink, it ensures a smooth, flush finish that prevents snagging and maintains product integrity. Ideal for HVAC systems, automotive panels, and machinery enclosures, this screw delivers reliable performance where vibration resistance and strong thread engagement are critical.
Specification Summary & Compliance
This screw features a 6-32 UNC coarse thread with a diameter of 0.138" and full threading for consistent engagement. It is designed for use with a No. 31 drill bit (0.12" diameter) and an 82° countersink angle. Manufactured to ASME B18.6.3 and SAE J933 specifications, it ensures precise dimensional tolerances (Class 2A) and reliable performance. The product is fully RoHS 3 (2015/863/EU) compliant, meeting environmental standards for safe use in various industries.
