S-92949A253 10-24 x 2" ASME B18.3 Stainless Steel Button Head Hex-Drive Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel and passivated finish for extended service life in harsh environments
• Precise thread engagement with Class 3A fit ensuring reliable, vibration-resistant connections in critical assemblies
• Exceptional mechanical strength delivering 70,000 psi tensile strength and Rockwell B55 hardness for heavy-duty applications
• Efficient installation through 1/8" hex drive design providing secure tool grip and reduced assembly time
• Optimized thread performance with UNC coarse threading and full threading along the 2" length for maximum holding power
• Reduced surface damage risk with rounded button head profile distributing clamping force evenly
• Regulatory compliance assurance meeting ASME B18.3 specifications and environmental standards including RoHS 3 and REACH

Professional Applications & Engineering Value

These 10-24 UNC rounded head screws deliver critical engineering solutions where corrosion resistance and thread precision are paramount. The combination of 18-8 stainless steel material with passivated surface treatment creates a protective barrier against chemical exposure and atmospheric corrosion, making them ideal for industrial equipment, marine components, and food processing machinery. The Class 3A thread fit ensures minimal play and superior vibration resistance in dynamic applications, while the coarse thread spacing provides rapid assembly and enhanced pull-out strength in softer materials. The fully threaded design along the 2" length maximizes engagement depth, distributing stress evenly to prevent joint failure under 70,000 psi tensile loads.

Specification Summary & Compliance

Manufactured to exacting dimensional tolerances with Class 3A thread fit per UNC standards, these screws guarantee precise mating with corresponding nuts and threaded holes. The 10-24 thread size with coarse spacing and right-hand thread direction follows industry-standard specifications. Compliance is verified with ASME B18.3 manufacturing standards, ensuring consistent quality and performance. Environmental responsibility is maintained through full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of restricted substances in the 18-8 stainless steel composition and passivated finish.
