S-93310A242 10-24 x 1/2" ASME B18.3, ASTM F879, MIL-DTL-18240 Thread-Locking Stainless Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with Nylon Patch thread locker ensures secure fastening in dynamic environments from -70° to 250°F
• Superior corrosion resistance from 18-8 Stainless Steel construction maintains integrity in harsh industrial conditions
• Precise Class 3A thread fit delivers reliable engagement and reduced risk of cross-threading during installation
• High-strength performance with 70,000 psi tensile strength and Rockwell B55 hardness withstands heavy mechanical loads
• Easy installation and removal with hex drive design provides superior torque transmission compared to standard drives
• Optimized head profile with rounded button design offers clean aesthetics while preventing snagging
• Full threading coverage ensures maximum grip length and uniform stress distribution along the entire fastener

Professional Applications & Engineering Value

These 10-24 UNC rounded head screws deliver critical vibration resistance in demanding applications where loosening under dynamic loads poses significant reliability concerns. The Nylon Patch thread locker embedded in the coarse thread spacing creates permanent friction that maintains clamp force without requiring secondary locking components. Manufactured from 18-8 Stainless Steel, these fasteners provide essential corrosion protection for outdoor equipment, marine components, and chemical processing systems where environmental exposure would degrade ordinary fasteners. The hex drive configuration enables higher torque application than Phillips or slotted drives, reducing installation time while preventing driver slippage and component damage. These fully threaded screws are engineered for machinery assembly, electrical enclosures, and structural frameworks where vibration resistance and material compatibility are paramount.

Specification Summary & Compliance

Manufactured to precise Class 3A thread fit tolerances with UNC coarse thread spacing and right-hand thread direction. Compliant with ASME B18.3, ASTM F879, and MIL-DTL-18240 specifications for dimensional accuracy and performance reliability. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance standards for use in regulated industries.
