- High tensile strength of 60,000 psi provides reliable load-bearing capacity and prevents premature failure in critical assemblies
- Rockwell B70 hardness maintains structural integrity under repeated stress and vibration
- Class 2A thread fit ensures smooth, precise installation and compatibility with standard UNC nuts and components
- Fully threaded design maximizes grip length and distributes clamping force evenly across the entire fastener
- Phillips No. 4 drive enables efficient installation with common tools, reducing assembly time and labor costs
- Compliance with ASME B18.6.3 guarantees consistent quality and dimensional accuracy for engineering applications
Professional Applications & Engineering Value
These 3/8"-16 UNC coarse thread screws are engineered to solve common industrial fastening challenges, particularly where vibration resistance and corrosion protection are critical. The zinc-plated steel construction provides a durable barrier against moisture and chemicals, extending service life in machinery, electrical enclosures, and structural assemblies. The rounded pan head design offers a low-profile, secure fit that minimizes snagging while the fully threaded body ensures maximum engagement in various material thicknesses. With 60,000 psi tensile strength and Rockwell B70 hardness, these screws maintain clamping force under dynamic loads, preventing loosening in automotive, manufacturing, and construction applications where reliability is paramount.
Specification Summary & Compliance
This rounded head screw features precise Class 2A thread fit with UNC coarse threading (3/8"-16) and complies with ASME B18.6.3 manufacturing standards. The product meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial and commercial applications worldwide. Dimensional accuracy is maintained with 1/2" length, 0.74" head diameter, and Phillips No. 4 drive specifications for consistent performance.
