Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ideal for harsh industrial environments
- Exceptional tensile strength of 70,000 psi ensures reliable performance under heavy loads and vibration
- Precise Class 3A thread fit provides secure, vibration-resistant fastening in demanding applications
- Hex drive design (7/32") allows for high-torque installation and easy removal with standard tools
- 82° countersink angle and flat head profile creates a flush, professional finish while distributing stress effectively
- Fully threaded length maximizes grip and holding power across the entire 3" engagement area
- Rockwell B55 hardness maintains thread integrity and prevents stripping during repeated use
Professional Applications & Engineering Value
This 3/8"-16 UNC flat head screw delivers critical engineering advantages where corrosion resistance and structural integrity are paramount. The combination of 18-8 stainless steel material and passivated finish creates a protective barrier against chemical exposure and atmospheric corrosion, making it ideal for marine equipment, food processing machinery, and outdoor structural applications. The coarse UNC threading with Class 3A fit ensures rapid installation and superior vibration resistance in heavy machinery, while the hex drive design accommodates high torque requirements without cam-out. The 82° countersink angle allows for seamless flush mounting in precision assemblies, reducing aerodynamic drag and preventing snagging in moving components.
Specification Summary & Compliance
This flat head screw features 3/8"-16 UNC coarse threads with precision Class 3A thread fit for consistent engagement. Manufacturing complies with ASME B18.3 specifications ensuring dimensional accuracy and performance reliability. The product is fully RoHS 3 (2015/863/EU) compliant and REACH (EC 1907/2006) compliant, meeting international environmental and safety standards for industrial use.
