S-90275A240 10-24 x 3/8" ASME B18.6.3 Steel Slotted Flat Head Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, extending service life in demanding environments
• Superior load-bearing capacity from 60,000 psi tensile strength, ensuring reliable performance under high-stress conditions
• Consistent installation and removal with Class 2A thread fit, providing precise engagement and reducing cross-threading risks
• Optimized flush mounting thanks to the 82° countersink angle and flat head design, creating smooth surface finishes
• Broad compatibility with UNC coarse threading and right-hand direction, fitting standard industrial components
• Durable mechanical properties from Rockwell B70 hardness, resisting wear and deformation during repeated use
• Full-length threading for maximum grip along the entire 3/8" length, improving holding power in various materials

Professional Applications & Engineering Value

This 10-24 UNC flat head slotted screw delivers exceptional engineering value in industrial assemblies where flush surface mounting is critical. The zinc-plated steel material provides reliable corrosion protection, while the 60,000 psi tensile strength ensures structural integrity in high-vibration environments. The Class 2A thread fit guarantees precise installation in machinery, electronic enclosures, and automotive components, minimizing the risk of thread stripping. The 82° countersink angle allows for seamless integration with standard countersunk holes, creating aerodynamically smooth surfaces in aerospace applications or preventing snagging in conveyor systems. These fully threaded fasteners offer superior pull-out resistance compared to partially threaded alternatives, making them ideal for securing thin materials and critical assemblies where vibration resistance is paramount.

Specification Summary & Compliance

Manufactured to exacting dimensional standards with Class 2A thread fit and UNC coarse threading, this screw maintains precise 10-24 thread size with 0.19" thread diameter. The product fully complies with ASME B18.6.3 specifications for dimensional accuracy and performance requirements. Environmental and safety regulations are met through RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) compliance, ensuring suitability for global industrial markets and restricted substance-free manufacturing.
