- Versatile right-hand threading suitable for standard assembly applications requiring coarse thread spacing.
Professional Applications & Engineering Value
This 8-32 UNC zinc-plated steel slotted screw is engineered to address common industrial challenges such as vibration loosening and environmental wear. The fillister head with its high, narrow profile provides excellent tool clearance and seating in countersunk or confined spaces, while the coarse UNC thread ensures quick assembly and strong holding power in materials like metal, plastic, or wood. The zinc plating offers a protective barrier against rust and corrosion, making these fully threaded screws ideal for machinery, electrical enclosures, and automotive components where durability and regulatory compliance are critical. With a tensile strength of 60,000 psi, they deliver reliable performance in heavy-duty and precision applications.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit per UNC standards, ensuring dimensional accuracy and interchangeability. It is manufactured in compliance with ASME B18.6.3 specifications and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial and commercial use.
