- High tensile strength of 120,000 psi provides reliable load-bearing capacity for medium-duty applications
- SAE Grade 5 steel construction ensures consistent performance and durability under stress
- Coarse UNC thread design enables faster installation and better resistance to vibration loosening
- Unified Standard Class 2A thread fit guarantees precise, interchangeable assembly with standard nuts
- External square drive head allows for high-torque application with standard wrenches
- Fully threaded 6" length provides maximum grip and adjustment flexibility in heavy assemblies
Professional Applications & Engineering Value
This 3/4"-10 UNC Square Head Screw delivers critical engineering solutions where medium strength and corrosion resistance are paramount. The SAE Grade 5 steel construction, combined with Rockwell C25 hardness, provides optimal balance between strength and machinability for structural connections in machinery, construction, and transportation equipment. The zinc yellow-chromate plating significantly extends service life in moist or chemically aggressive environments, while the coarse thread configuration prevents cross-threading and maintains integrity under dynamic loads. The external square drive design ensures secure tool engagement during high-torque installation, making it ideal for heavy-duty bolting applications where reliability cannot be compromised.
Specification Summary & Compliance
This square head screw features Unified Standard Class 2A thread tolerances with 3/4"-10 UNC coarse thread specifications. Manufactured to meet ASME B18.2.1 dimensional standards and SAE J429 material requirements for Grade 5 fasteners. The product maintains 120,000 psi tensile strength and Rockwell C25 hardness throughout its fully threaded 6" length, ensuring consistent performance across industrial applications.
