Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance in demanding applications, reducing the risk of fastener failure
- Precise Class 3A thread fit provides superior engagement and vibration resistance, minimizing loosening in critical assemblies
- Integrated nylon patch thread locker maintains secure fastening across a wide temperature range (-70° to 250°F) without requiring additional adhesives
- Black-oxide finish on alloy steel offers enhanced corrosion resistance and durability in harsh industrial environments
- Hex socket drive design allows for high-torque installation and removal in confined spaces with standard tools
- Full threading along the 3/4" length enables flexible positioning and consistent clamping force throughout the engagement
- Compliance with major industry standards including ASME B18.3 and ASTM A574 guarantees consistent quality and interchangeability
Professional Applications & Engineering Value
These 10-32 UNF socket head cap screws deliver critical engineering solutions where precision and reliability are paramount. The Black-Oxide Alloy Steel construction combined with Class 3A fine threads provides exceptional resistance to vibrational loosening in machinery, automotive, and aerospace applications. The integrated nylon patch thread locker eliminates the need for separate locking compounds while maintaining performance across extreme temperature fluctuations (-70° to 250°F). The hex drive socket head design ensures maximum torque transmission during installation, making these industrial fasteners ideal for high-stress assemblies where space constraints prevent conventional wrench access.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread fit precision and UNF fine thread spacing. These screws meet ASTM A574 material standards and demonstrate full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The fully threaded design maintains consistent engagement while the Rockwell C37 hardness rating ensures durability under repeated loading conditions.
