Professional Applications & Engineering Value
These zinc-plated steel screws with integrated split lock washers deliver critical vibration resistance in industrial environments where machinery and equipment experience constant movement. The UNC coarse threading combined with Class 2A thread fit ensures rapid installation while maintaining precise tolerance control. The Phillips pan head design provides a low-profile fastening solution that distributes clamping force effectively across joined surfaces. Engineered for industrial assembly applications, these fully threaded screws maintain their 60,000 psi tensile strength even under repetitive stress cycles, making them ideal for automotive components, electrical enclosures, and machinery where locking washer fasteners are essential for long-term reliability.
Specification Summary & Compliance
Manufactured to exacting ASME B18.13 standards with Class 2A thread fit precision and UNC coarse threading (6-32 size). Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The zinc-plated steel construction meets specified dimensions including 0.27" head diameter, 1/2" length, and integrated split lock washer with 0.261" OD. Thread specifications include right-hand direction and coarse spacing suitable for industrial fastening applications requiring reliable performance and regulatory compliance.
