Key Features & Benefits at a Glance
- Exceptional tensile strength of 120,000 PSI ensures reliable performance in high-stress and heavy-duty applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide finish on alloy steel extends service life in harsh or humid industrial environments.
- Precise Class 3A thread fit provides tighter tolerances for secure, vibration-resistant assemblies, minimizing loosening over time.
- Integrated flange design eliminates the need for a separate washer, distributing load evenly and speeding up installation.
- Coarse UNC threading allows for quicker installation and better performance in softer materials or where debris is present.
- Hex drive compatibility with a 7/32" key offers high torque transfer and reduces stripping, ideal for automated or manual assembly.
- Full threading along the 1-1/2" length ensures maximum grip and adjustability, accommodating various material thicknesses.
Professional Applications & Engineering Value
Engineered for demanding environments, this black-oxide alloy steel rounded head screw combines high tensile strength and corrosion resistance to address common industrial challenges like vibration-induced loosening and environmental wear. The flanged design and Class 3A UNC coarse threads provide a secure, flush fit that reduces assembly time and maintenance needs in machinery, structural frames, and automotive components. Its hex drive ensures efficient torque application, making it a reliable choice for heavy-duty fastening where durability and compliance with stringent standards are critical.
