- External hex drive design enables quick installation and removal with standard tools, reducing assembly time
- Full threading along the 1" length maximizes grip strength and distributes load evenly
Professional Applications & Engineering Value
These 18-8 stainless steel hex head screws with integrated silicone O-rings address critical sealing challenges in industrial systems where fluid containment is paramount. The coarse UNC threads and Class 2A fit provide reliable engagement in high-vibration environments, preventing loosening while the silicone sealing element maintains integrity across extreme temperature fluctuations from -80° to 400°F. Engineered for high-pressure applications up to 20,000 PSI, these fasteners are ideal for hydraulic systems, pneumatic equipment, and processing machinery where leak-proof performance is non-negotiable. The combination of corrosion-resistant stainless steel and durable silicone sealing creates a maintenance-free solution that reduces downtime in critical operations.
Specification Summary & Compliance
This 1/4"-20 x 1" hex head screw features UNC coarse threads with Class 2A tolerance for precise fit, manufactured from 18-8 stainless steel with Rockwell B85 hardness and 80,000 PSI tensile strength. The silicone O-ring provides sealing capability for maximum hole diameter of 0.269". Product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
