S-94288A222 5/16"-18 x 2" Extreme-Strength Stainless Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 450 stainless steel construction, ideal for harsh industrial environments
• Superior load-bearing capacity thanks to 170,000 psi tensile strength for heavy-duty applications
• Enhanced durability and wear resistance from Rockwell C38 hardness, reducing replacement frequency
• Secure and reliable fastening with Class 2A thread fit and coarse UNC threading for vibration resistance
• Easy installation and removal using standard external hex drive tools, saving time on assembly lines
• Improved load distribution from the integrated flange, minimizing surface damage and loosening
• Optimized for partial-thread applications allowing precise clamping in machinery and structural assemblies

Professional Applications & Engineering Value

This 5/16"-18 UNC hex head screw in 450 stainless steel is engineered to address common industrial challenges like corrosion, high stress, and vibration-induced failures. The coarse UNC threading and Class 2A thread fit ensure quick assembly and reliable hold in materials prone to expansion or contraction, such as in construction equipment and automotive frames. The flanged design distributes clamping force evenly, preventing damage to soft surfaces and reducing maintenance needs. With partial threading, it provides precise grip control in heavy-duty fastening scenarios, making it a go-to choice for machinery, metal fabrications, and outdoor structures where durability and performance are critical.

Specification Summary & Compliance

This screw adheres to UNC thread standards with a Class 2A thread fit for consistent dimensional accuracy. It meets industry specifications for inch system fasteners, including precise thread size (5/16"-18), length (2"), and flange diameter (5/8"). Manufactured from 450 stainless steel, it complies with material performance benchmarks and is suitable for applications requiring resistance to environmental factors. While specific certifications like RoHS or REACH are not detailed, the product is designed to align with common industrial standards for quality and reliability in mechanical assemblies.
