Professional Applications & Engineering Value

Engineered for demanding industrial environments, these 450 Stainless Steel hex head screws deliver critical corrosion resistance where moisture, chemicals, or outdoor exposure threaten fastener integrity. The UNC coarse thread configuration ensures rapid installation and reliable performance in materials where fine threads might strip or clog. With partial threading and integrated flange, these screws provide distributed bearing pressure and vibration resistance ideal for machinery assemblies, structural frames, and equipment mounting. The external hex drive accommodates high-torque applications while the Class 2A thread fit maintains consistent engagement across production runs, reducing assembly variables in manufacturing and maintenance operations.

Specification Summary & Compliance

These screws feature precision UNC coarse threading with Class 2A fit per ASME B1.1 standards, ensuring consistent dimensional accuracy across production batches. The 1/4"-20 thread size with 2" length and 5/16" head width maintains inch system compatibility for North American industrial applications. Manufacturing complies with industry standards for 450 Stainless Steel composition, delivering optimal mechanical properties with 170,000 psi tensile strength and Rockwell C38 hardness. The flanged design and partial threading provide engineered solutions for specific clamping requirements while maintaining compliance with industrial fastener specifications.
