Professional Applications & Engineering Value
These Bumax 88 stainless steel hex head screws deliver exceptional performance in demanding industrial environments where corrosion resistance and mechanical strength are critical. The 5/16"-18 UNC coarse thread configuration provides superior vibration resistance and rapid installation in heavy machinery, structural assemblies, and processing equipment. The external hex drive design ensures positive tool engagement, reducing slippage during high-torque applications. With 110,000 psi tensile strength and partial threading, these fasteners maintain structural integrity while providing optimal clamping force distribution. Ideal for chemical processing, marine applications, and food processing equipment where RoHS 3 and REACH compliance meets stringent environmental and safety standards.
Specification Summary & Compliance
Manufactured to ASME B18.2.1 specifications with Class 2A thread fit tolerance for consistent dimensional accuracy. Features 5/16"-18 UNC coarse threads with partial threading extending 7/8" minimum. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The inch system measurement ensures compatibility with North American industrial standards and replacement part requirements.
