S-92360A210 10-24 x 1/4" ASME B18.3, ASTM F835, MIL-DTL-18240 Thread-Locking Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Vibration-resistant locking with permanent nylon patch that maintains secure fastening in demanding environments from -70° to 250°F
• Exceptional durability from black-oxide alloy steel construction providing corrosion resistance and extended service life
• Superior strength performance with 120,000 psi tensile strength and Rockwell C39 hardness for heavy-duty applications
• Precise thread engagement with Class 3A fit and UNC coarse threads ensuring reliable installation and vibration resistance
• Easy installation and removal with hex drive design providing positive tool engagement and reduced stripping risk
• Full thread coverage along the entire 1/4" length for maximum grip and load distribution
• Industry compliance assurance meeting multiple military and industrial standards for quality and reliability

Professional Applications & Engineering Value

These 10-24 UNC nylon patch locking screws deliver critical vibration resistance in industrial machinery, automotive assemblies, and electronic enclosures where loosening under dynamic loads poses significant failure risks. The black-oxide alloy steel construction combined with Class 3A thread fit ensures precise mating with components while the coarse threading facilitates quicker assembly in production environments. The permanent nylon patch locking technology activates immediately upon installation, eliminating the need for secondary locking mechanisms and reducing assembly time. Engineered for high-tensile applications requiring 120,000 psi strength, these hex drive rounded head screws provide reliable fastening solutions in vibration-prone equipment, military hardware, and precision industrial systems where maintenance access is limited.

Specification Summary & Compliance

Manufactured to Class 3A thread fit tolerance with UNC coarse threading (10-24 size) and full compliance with ASME B18.3, ASTM F835, and MIL-DTL-18240 specifications. These screws feature complete RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for global environmental regulations. The black-oxide surface treatment on alloy steel provides corrosion protection while maintaining dimensional accuracy per industrial standards.
