Professional Applications & Engineering Value
Engineered for industrial applications requiring robust fastening solutions, these 10-24 UNC zinc-plated steel truss head screws address common challenges like vibration loosening and environmental exposure. The wide rounded truss head distributes clamping force over a larger area, minimizing the risk of material damage in soft substrates or painted surfaces. With a coarse thread profile and Class 2A thread fit, they provide rapid assembly and reliable holding power in metal, plastic, and wood components. The zinc plating offers a protective barrier against rust and corrosion, making these fully threaded screws ideal for machinery, electrical enclosures, and automotive assemblies where durability and regulatory compliance are critical.
Specification Summary & Compliance
This product meets ASME B18.6.3 specifications for dimensional accuracy and performance, featuring a Class 2A thread fit for consistent engagement. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring safe use in industrial and consumer applications. The screw maintains precise thread geometry with UNC coarse spacing and is manufactured to deliver reliable tensile strength and hardness as specified.
