Professional Applications & Engineering Value
Engineered for demanding industrial applications, this chrome-plated stainless steel oval head screw combines material excellence with precision UNC threading to solve common fastening challenges. The 18-8 stainless steel base with chrome plating delivers exceptional corrosion resistance, preventing failure in moist or chemical-exposed settings. Its partially threaded 1/4"-20 configuration ensures optimal grip in assemblies where vibration resistance is critical, while the Phillips drive facilitates quick installation without specialized equipment. Ideal for machinery, automotive, and construction uses, it maintains integrity under 80,000 psi tensile loads, reducing maintenance needs and downtime in heavy-duty fastening systems.
Specification Summary & Compliance
This screw adheres to UNC coarse thread standards with Class 2A thread fit for consistent dimensional accuracy. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met. Critical dimensions include a 1/4"-20 thread size, 2 1/2" length, and 0.462" head diameter, with material hardness rated at Rockwell B80 for durable performance.
