S-92360A669 6-32 x 3/4" MIL-DTL-18240 Thread-Locking Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior vibration resistance with integrated nylon patch thread locker, preventing loosening in high-stress environments
• Exceptional tensile strength of 120,000 psi ensures reliable performance under heavy loads and mechanical stress
• Enhanced corrosion protection from black-oxide coating on alloy steel, extending service life in harsh conditions
• Precise Class 3A thread fit provides secure engagement and reduces cross-threading risks during installation
• Wide temperature tolerance (-70° to 250°F) maintains locking integrity across extreme thermal cycles
• Optimized hex drive design (5/64") enables efficient torque application and reduces tool slippage
• Full threading coverage maximizes grip length and distributes clamping forces evenly

Professional Applications & Engineering Value

These black-oxide alloy steel rounded head screws address critical vibration-induced failure points in industrial assemblies. The nylon patch thread locker creates permanent friction locks without compromising UNC coarse threads, making them ideal for machinery, automotive subsystems, and electronic enclosures where thermal cycling and constant motion exist. Their Rockwell C37 hardness combined with 120,000 psi tensile strength ensures structural integrity in high-load applications, while the fully threaded design provides consistent clamping force across the entire engagement length. The rounded head profile with hex drive facilitates flush mounting and tool access in confined spaces.

Specification Summary & Compliance

Manufactured to Class 3A thread fit tolerances with UNC 6-32 coarse threading and right-hand orientation. Fully compliant with MIL-DTL-18240 military specifications for material and performance requirements. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in regulated industries.
